The charging plate creates magnetic fluxing. The charging plate and the adjacent coil can induce current without any contact. By the new trends, wireless charging got more social attention to the outside world as an alternative method for primitive wired charging. Even though wireless charging was implemented to various electronics industries, it is still proven that wired charging is faster than the wireless. But can make the gadget hot, which may not be good for the battery efficiency. The wireless charging does not degrade the battery. A vehicle that is powered by an electric motor rather than a typical petrol or diesel engine is referred to as an electric vehicle. The electric motor is powered by rechargeable batteries. In this article, the dynamic wireless charging of electric vehicles introduces a new methodology of charging even when the vehicle is in motion. The dynamic wireless charging is proposed to allow power transfer to the electric vehicles when they are in motion. Multiple inductive pads should be buried under the roadways. The inductive pads should be energized by a power supply. The track which is dedicated for the wireless charging should have enough distance so that the vehicles can charge up to a stable value until they leave the charging track. This proposed methodology reduces unnecessary time wastage for charging of vehicles. Hardware results obtained the primary pads mounted on road and power supply for primary roads. Besides, it will flow the efficient inductive power transfer and time saving opportunity.

The expansion on the use of Electric Vehicles demands new mechanisms to ease the charging process, making it autonomous and with a reduced user intervention. This paper reviews the technologies applied to the wireless charge of Electric Vehicles. In particular, it focuses on the technologies based on the induction principle, the capacitive-based techniques, those that use radiofrequency waves and the laser powering. As described, the convenience of each technique depends on the requirements imposed on the wireless power transfer. Specifically, we can state that the power level, the distance between the power source and the electric vehicle or whether the transfer is executed with the vehicle on the move or not or the cost are critical parameters that need to be taken into account to decide which technology to use. In addition, each technique requires some complementary electronics. This paper reviews the main components that are incorporated into these systems and it provides a review of their most relevant configurations.

<p>In these days, electric vehicles are enthusiastically researched as a countermeasure to air pollution, although these do not have practicality compared to gasoline-powered vehicles. The aim of this study is to transport energy wirelessly and efficiently to an electric vehicle. To accomplish this, we focused on frequency of an alternating current (AC) power supply, and suggested a method which determined the value of it constantly. In particular, a wireless power transfer circuit and a lithium-ion battery in an electric vehicle were expressed with an equivalent circuit, and efficiency of energy transfer was calculated. Furthermore, the optimal frequency which maximizes efficiency was found, and the behavior of voltage was demonstrated on a secondary circuit. Finally, we could obtain the larger electromotive force at the secondary inductor than an input voltage.</p>

Electric vehicles (EVs) are becoming more popular as people become more concerned about global issues, such as fossil fuel depletion and global warming, which cause severe climate change. Wired charging infrastructure is inefficient because it requires the construction of one charging station for each electric vehicle. As a result, wireless power transfer via magnetic coupling, which is small, compact, and may be placed underground, is a promising technology for the future of charging electric vehicles. One of the disadvantages of wireless power transfer is that efficiency drops rapidly as air gaps grow larger, and it is particularly sensitive to other electrical characteristics such receiver unit capacitance. The purpose of this paper is to investigate the coil parameter, more specifically the outer diameter of wireless power transfer coil effects on the wireless power transfer efficiency at various air gaps and receiver capacitance values for EV applications. The simulations show that a larger outer diameter coil has a better power transfer efficiency at larger air gaps and a more stable range.

Electrical vehicles have to be periodically recharged. Currently, they are plugged to power station by cables. Wireless Power Transfer (WPT) Systems could be used instead of traditional cable connection to charge the batteries of electric vehicles. These systems are based on a couple of coils, one on the vehicle bottom and one under the road connected to a power station. Nevertheless, these systems are affected by the magnetic characteristic of the coupling coils, so that these devices should be carefully designed. In this paper, a pair of faced pancake coils equipped with ferrite core is considered. The possible geometries of the coils are designed using genetic optimization algorithms searching for optimal mutual inductance and saving in copper. This paper presents the analysis of the Pareto solutions obtained using automatic design strategy.

This paper focuses on the modeling and implementation of an Electric Vehicle (EV) wireless charging system based on inductively coupled power transfer (ICPT) technique where electrical energy can be wirelessly transferred from source to vehicle battery. In fact, the wireless power transfer (WPT) system can solve the fundamental problems of the electric vehicle, which are the short battery life of the EV due to limited battery storage and the user safety by handling high voltage cables. In addition, this paper gives an equivalent electrical circuit of the DC-DC converter for WPT and comprises some basic components, which include the H-bridge inverter, inductive coupling transformer, filter, and rectifier. The input impedance of ICPT with series-series compensation circuit, their phases, and the power factor are calculated and plotted by using Matlab scripts programming for different air gap values between the transmitter coil and receiver coil. The simulation results indicate that it is important to operate the system in the resonance state to transfer the maximum real power from the source to the load. A mathematical expression of optimal equivalent load resistance, corresponding to a maximal transmission efficiency of a wireless charging system, was demonstrated in detail. Finally, a prototype of a wireless charging system has been constructed for using two rectangular coils. The resonant frequency of the designed system with a 500 × 200 mm transmitter coil and a 200 × 100 mm receiver coil is 10 kHz. By carefully adjusting the circuit parameters, the implementation prototype have been successfully transferred a 100 W load power through 10 cm air gap between the coils.

Recently, the number of electric vehicles (EVs) is increasing due to the decline of oil resources and the rising of greenhouse gas emissions. However, EVs have not received full acceptance by consumers due to the limitations of the stored energy and charging problems. The dynamic or in-motion charging solution has become a suitable choice to solve the battery-related issues. Many researchers and vehicle manufacturers are working to develop an efficient charging system for EVs. In order to improve the efficiency of the dynamic wireless power transfer (DWPT), the electromagnetic coupling coefficient between the two parts of the coupler must be maximized. This paper was dedicated to find the optimal topology of a magnetic coupler with the best coupling factor while taking in consideration the displacement and the misalignment of the EV. The article is introduced by developing a methodology for characterizing the electrical parameters of couplers, followed by a comparative study of different forms of coils suitable for dynamic charging of electric vehicles. The particularity of the proposed study concerned the overall dimensions, or the areas occupied by the windings of the coils remaining the same for all the chosen shapes and corresponding to the surface that is actually available under the EV. Simulation and experimental tests were carried out to validate the proposed study.

Dynamic wireless power transfer (DWPT) of electric vehicles (EVs) is the future of urban mobility. The DWPT is often based on a series of short track pads embedded in road pavement that wirelessly transfers electrical energy to EVs equipped with a pickup coil for battery charging. An open problem with this technology is the variation of the coupling factor as a vehicle switches from one transmitting coil to another during its motion. This can cause a significant change in power with possible power spikes and holes. In order to overcome these issues, a new architecture is here proposed based on two pick-up coils mounted in the vehicle underneath. These identical receiver coils are placed in different positions under the vehicle (one in front and the other in the rear) and are activated one at a time so that inductive coupling is always good enough. This innovative configuration has two main advantages: (i) it maintains a nearly constant coupling factor, as well as efficiency and transferred power, as the vehicle moves along the electrified road; (ii) it significantly reduces the cost of road infrastructure. An application is presented to verify the proposed two-coil architecture in comparison with the traditional one-coil. The results of the investigation show the significant improvement achieved in terms of maximum power variation which is nearly stable with the proposed two-coil architecture (only 2.8% variation) while there are many power holes with the traditional single coil architecture. In addition, the number of the required transmitting coils is significantly reduced due to a larger separation between adjacent coils.

Full textAbstract:
Wireless power transfer is a method of transferring electric power from a transmitter to a receiver without requiring any physical connection between the two. Dynamic Wireless Power Transfer (DWPT) entails having the transmitters buried under the roadway and the receiver unit being installed on the Electric Vehicle (EV). In this method, EVs are charged while driving over the transmitters as they receive bursts of electric energy at the time of significant alignment between transmitters and receivers. Compared to the stationary charging method which involves parking the EV for long hours for a full charge, the dynamic charging method (i.e., DWPT) offers convenience as the vehicle gets charged while driving. It also facilitates extended driving range of EVs. Despite offering these advantages, DWPT causes a few significant issues. DWPT charging results in a transient power profile both at grid side and EV side, which not only hampers grid-side regulation but also affects EV-battery longevity. To address these two issues, both grid-side and EV-side energy management are needed to be employed to protect the grid and the vehicle from sudden exposure to harmful power transients. In this dissertation, the grid-side and EV-side energy management methods have been investigated. Firstly, a detection system to safely detect the vehicle on charging lane is proposed. This detection system is used to facilitate safe and efficient operation of DWPT chargers on EV roadways. Secondly, A novel DWPT system is proposed, which reduces the grid-side power transients with minimal additional hardware requirements. Finally, an EV-side energy management system is proposed which reduces the exposure of EV batteries to pulsating DPWT-power, thereby helping batteries to last longer.

Full textAbstract:
Contactless Electric Vehicle (EV) charging based on magnetic resonant induction is an emerging technology that can revolutionize the future of the EV industry and transportation systems by enabling an automated and convenient charging process. However, in order to make this technology an acceptable alternative for conventional plug-in charging systems it needs to be optimized for different design measures. Specifically, the efficiency of an inductive EV charging system is of a great importance and should be comparable to the efficiency of conventional plug-in EV chargers.
The aim of this study is to develop solutions that contribute to the design enhancement of inductive EV charging systems. Specifically, generalized physics-based design optimization methods that address the trade-off problem between several key objectives including efficiency, power density, misalignment tolerance, and cost efficiency considering critical constraints are developed. Using the developed design methodology, a 3.7kW inductive charging system with square magnetic structures is investigated as a case study and a prototype is built to validate the optimization results. The developed prototype achieves 93.65% efficiency (DC-to-DC) and a power density of 1.65kW/dm3.
Also, self-tuning power transfer control methods with resonance frequency tracking capability and bidirectional power transfer control are presented. The proposed control methods enhance the efficiency of power converters and reduce the Electromagnetic Interference (EMI) by enabling soft-switching operations. Several simplified digital controllers are developed and experimentally implemented. The controllers are implemented without the use of DSP/FPGA solutions. Experimental tests show that of the developed simplified controllers can effectively regulate the power transfer around the desired value. Moreover, the experiments show that compared to conventional converters, the developed converters can achieve 4% higher efficiency at low power levels.
Moreover, enhanced matrix converter topologies that can achieve bidirectional power transfer and high efficiency with a reduced number of switching elements are introduced. The self-tuning controllers are utilized to design and develop control schemes for bidirectional power transfer regulation. The simulation analyses and experimental results show that the developed matrix converters can effectively establish bidirectional power transfer at the desired power levels with soft-switching operations and resonance frequency tracking capability. Specifically, a direct three-phase AC-AC matrix converter with a reduced number of switches (only seven) is developed and built. It is shown that the developed converters can achieve efficiencies as high as 98.54% at high power levels and outperform conventional two-stage converters.

As electric vehicles (EVs) become more popular, the utility companies are forced to increase power generations in the grid. However, these EVs are capable of providing power to the grid to deliver different grid ancillary services in a concept known as vehicle-to-grid (V2G) and grid-to-vehicle (G2V), in which the EV can serve as a load or source at the same time. These services can provide more benefits when they are integrated with Photovoltaic (PV) generation. The proper modeling, design and control for the power conversion systems that provide the optimum integration among the EVs, PV generations and grid are investigated in this thesis.
The coupling between the PV generation and integration bus is accomplished through a unidirectional converter. Precise dynamic and small-signal models for the grid-connected PV power system are developed and utilized to predict the system’s performance during the different operating conditions. An advanced intelligent maximum power point tracker based on fuzzy logic control is developed and designed using a mix between the analytical model and genetic algorithm optimization.
The EV is connected to the integration bus through a bidirectional inductive wireless power transfer system (BIWPTS), which allows the EV to be charged and discharged wirelessly during the long-term parking, transient stops and movement. Accurate analytical and physics-based models for the BIWPTS are developed and utilized to forecast its performance, and novel practical limitations for the active and reactive power-flow during G2V and V2G operations are stated. A comparative and assessment analysis for the different compensation topologies in the symmetrical BIWPTS was performed based on analytical, simulation and experimental data. Also, a magnetic design optimization for the double-D power pad based on finite-element analysis is achieved. The nonlinearities in the BIWPTS due to the magnetic material and the high-frequency components are investigated rely on a physics-based co-simulation platform. Also, a novel two-layer predictive power-flow controller that manages the bidirectional power-flow between the EV and grid is developed, implemented and tested. In addition, the feasibility of deploying the quasi-dynamic wireless power transfer technology on the road to charge the EV during the transient stops at the traffic signals is proven.

Wireless Power Transfer (WPT) systems transfer electric energy from a source to a load without any wired connection. WPTs are attractive for many industrial applications because of their advantages compared to the wired counterpart, such as no exposed wires, ease of charging, and fearless transmission of power in adverse environmental conditions. Adoption of WPTs to charge the on-board batteries of an electric vehicle (EV) has got attention from some companies, and efforts are being made for development and improvement of the various associated topologies. WPT is achieved through the affordable inductive coupling between two coils termed as transmitter and receiver coil. In EV charging applications, transmitter coils are buried in the road and receiver coils are placed in the vehicle. Inductive WPT of resonant type is commonly used for medium-high power transfer applications like EV charging because it exhibits a greater efficiency.
This thesis refers to a WPT system to charge the on-board batteries of an electric city-car considered as a study case. The electric city-car uses four series connected 12V, 100A•h VRLA batteries and two in-wheel motors fitted in the rear wheels, each of them able to develop a peak power of 4 kW to propel the car. The work done has been carried out mainly in three different stages; at first an overview on the wired EV battery chargers and the charging methodologies was carried out. Afterwards, background of different WPT technologies are discussed; a full set of Figures of Merit (FOM) have been defined and are used to characterize the resonant WPTs to the variations in resistive load and coupling coefficient. In the second stage, the WPT system for the study case has been designed. In the third stage, a prototypal of the WPT system has been developed and tested.
Design of the WPT system is started by assessing the parameters of the various sections and by estimating the impact of the parameters of the system on its performance. The design process of the coil-coupling has come after an analysis of different structures for the windings, namely helix and spiral, and different shapes for the magnetic core; further to the preliminary results that have shown the advantages of the spiral structure, a more detailed analysis has then been executed on this structure. The coil design has encompassed the determination of the inductive parameters of the two-coil coupling as a function of the coil distance and axial misalignment. Both the analysis and the design was assisted by a FEM-approach based on the COMSOL code.
Design of the power supply stages of the WPT system has consisted of the assessment of values and ratings of a) the capacitors that make resonant the coil-coupling, b) the power devices of the PFC rectifier and of the high frequency inverter (HF) that feeds the transmitting coil, c) the power devices of the converters supplied by the receiver coil: the rectifier diode and the in-cascade chopper that feeds the battery in a controlled way. For the converters that operate at high frequency (inverter and the rectifier in the receiver section), power electronic devices of the latest generation (the so-called Wide Band Gap (WBG) devices) have been used in order to maximize the efficiency of the WPT system.
A prototypal WPT battery charger was arranged by using available cards with the power and signal circuits. Relevant experimental activities were: a) measurement of the parameters of the coils, b) desk assembling of the prototype, and c) conducting tests to verify proper operation of the prototype.
The thesis work includes also a brief overview of i) emerging topics on WPT systems such as on-line electric vehicle (OLEV), ii) shielding of the magnetic fields produced by a WPT system, and iii) standards on WPT operation. These three issues play a significant role in the advancement of the WPT technology.
The thesis work has been carried out at the Laboratory of “Electric systems for automation and automotive” headed by Prof. Giuseppe Buja. The laboratory belongs to the Department of Industrial Engineering of the University of Padova, Italy.I sistemi per il trasferimento di potenza wireless (WPT) trasferiscono energia elettrica da una sorgente ad un carico senza alcuna connessione via cavo. I sistemi WPT sono attraenti per molte applicazioni industriali grazie ai loro vantaggi rispetto alla controparte cablata, come l’assenza di conduttori esposti, la facilità di ricarica e la trasmissione senza rischi della potenza in condizioni ambientali avverse. L’adozione di sistemi WPT per la carica delle batterie di bordo di un veicolo elettrico (EV) ha ricevuto l'attenzione di alcune aziende, e sforzi sono stati fatti per lo sviluppo e il miglioramento delle varie topologie ad essi associate. Il WPT è ottenuto tramite l'accoppiamento induttivo tra due bobine, definite bobina trasmittente e bobina ricevente. Nelle applicazioni per la carica delle batterie, le bobine trasmittenti sono installate sotto il manto stradale mentre le bobine riceventi sono poste a bordo del veicolo. Il WPT induttivo di tipo risonante è comunemente utilizzato nelle applicazioni per il trasferimento di potenze medio-alte, come la carica degli EV, perché presenta una maggiore efficienza. Questa tesi tratta un sistema WPT per caricare le batterie di bordo di una city-car elettrica considerato come caso di studio. La city-car elettrica utilizza quattro batterie da 12V, 100A•h VRLA collegate in serie e due motori-ruota montati sull’assale posteriore, ognuno in grado di sviluppare una potenza di picco di 4 kW per la propulsione del veicolo. Il lavoro svolto è stato effettuato principalmente in tre fasi diverse; in un primo momento è stata effettuata una panoramica sui caricabatteria cablati per EV e sulle metodologie di ricarica. Successivamente, sono stati discussi i principi base di diverse tecnologie WPT; è stato definito un insieme di figure di merito (FOM) che sono state utilizzate per caratterizzare il comportamento dei WPT risonanti rispetto alle variazioni di carico resistivo e al coefficiente di accoppiamento. Nella seconda fase, è stato progettato il sistema WPT per il caso di studio. Nella terza fase, è stato sviluppato e sperimentato un prototipo del sistema WPT. La progettazione del sistema WPT è stata iniziata con una valutazione dei parametri delle varie sezioni e stimando l'impatto dei parametri del sistema sulle sue prestazioni. La progettazione della bobina di accoppiamento è stata effettuata dopo l'analisi di avvolgimenti con strutture diverse, ovvero elica e spirale, e con forme differenti del nucleo magnetico; a seguito dei risultati preliminari che hanno mostrato i vantaggi della struttura a spirale, è stata poi eseguita un'analisi più dettagliata su questa struttura. Il progetto della bobina ha compreso la determinazione dei parametri induttivi dell’accoppiamento in funzione della distanza e del disallineamento assiale delle bobine. Sia l'analisi che la progettazione sono state assistite da un approccio FEM basato sul codice COMSOL. La progettazione degli stadi di alimentazione del sistema WPT è consistita nella valutazione dei valori e dei dati di targa di a) i condensatori che rendono risonante l’accoppiamento tra le bobine, b) i dispositivi di potenza del raddrizzatore PFC e dell'inverter ad alta frequenza (HF) che alimenta la bobina di trasmissione, c) i dispositivi di potenza dei convertitori alimentati dalla bobina ricevente, segnatamente il raddrizzatore a diodi e il chopper collegato a valle che carica la batteria in modo controllato. Per i convertitori che operano ad alta frequenza (l’invertitore e il raddrizzatore della sezione ricevente), sono stati utilizzati dispositivi elettronici di potenza di ultima generazione (i cosiddetti dispositivi Wide Band Gap (WBG)) al fine di massimizzare l'efficienza del sistema WPT. E’ stato realizzato un caricabatteria WPT prototipale utilizzando schede elettroniche disponibili in Laboratorio con i circuiti di potenza e di segnale. Le relative attività sperimentali sono state: a) misurazione dei parametri delle bobine, b) assemblaggio a banco del prototipo, e c) esecuzione di prove sperimentali per verificare il corretto funzionamento del prototipo. Il lavoro di tesi comprende anche una breve panoramica su temi emergenti in materia di sistemi WPT come i) IL WPT dinamico, chiamato anche “on-line electric vehicle” (OLEV), ii) la schermatura dei campi magnetici prodotti da un sistema WPT, e iii) la normativa sui sistemi WPT. Questi tre temi svolgono un ruolo significativo nello sviluppo della tecnologia WPT. Il lavoro di tesi è stato effettuato presso il Laboratorio di “Sistemi elettrici per l'automazione e la veicolistica” diretto dal Prof. Giuseppe Buja. Il Laboratorio fa parte del Dipartimento di Ingegneria Industriale dell'Università degli Studi di Padova, Italia.

Full textAbstract:
In the years 1884-1889, after Nicola Tesla invented "Tesla Coil", wireless power transfer (WPT) technology is in front of the world. WPT technologies can be categorized into three groups: inductive based WPT, magnetic resonate coupling (MRC) based WPT and electromagnetic radiation based WPT. MRC-WPT is advantageous with respect to its high safety and long transmission distance. Thus it plays an important role in the design of wireless electric vehicle (EV) charging systems. The most significant drawback of all WPT systems is the low efficiency of the energy transferred. Most losses happen during the transfer from coil to coil. This thesis proposes a novel coil design and adaptive hardware to improve power transfer efficiency (PTE) in magnetic resonant coupling WPT and mitigate coil misalignment, a crucial roadblock to the acceptance of WPT for EV. In addition, I do some analysis of multiple segmented transmitters design for dynamic wireless EVs charging and propose an adaptive renewable (wind) energy-powered dynamic wireless charging system for EV.

Full textAbstract:
Wireless charging of electric vehicle (EV) batteries by inductive power transfer (IPT) offers unique advantages compared to conventional conductive chargers. Due to the absence of a galvanic connection, the charging process requires no user interaction and no moving of mechanical components. For public transport systems, e.g., public buses or tramways, this makes possible a fully automated opportunity charging at bus stations, taxicab stands, or traffic lights. The schematic of wireless battery charger (WBC) is made of two stages, one is transmitter stage and another one is receiver stage. Both the stages include coils and capacitors to resonate at the supply frequency along with power conversion circuits. The transmitter coil is buried in the ground while receiving coil is situated in the vehicle.
Based on the connection of resonating capacitors four topologies are possible which can be divided into two arrangements i) transmitter capacitor in series while receiver capacitor is in either series or in parallel, giving rise to SS and SP topologies, ii) transmitting capacitor in parallel while receiving capacitor is in either series or in parallel, giving rise to PS and PP topologies. In the thesis, these topologies have been studied in detail in terms of efficiency, power sizing of supply inverter and resonating coils, behavior under the extreme condition of open and short circuit of the receiver.
Power conversion circuitry of a WBC system includes a diode rectifier to supply the load with a direct voltage and resorts to different solutions for charging the battery. The two most used solutions are either in a straightforward manner through the diode rectifier or through a chopper in cascade to the diode rectifier. These two arrangements have been discussed and compared in terms of efficiency and power sizing of supply inverter and transmitting and receiving coil, including the selection of the optimum chopper input voltage.
Due to aging and thermal effect, the parameters of the reactive components of a WBC system may change and this can deviates the resonance frequency from the supply frequency. In this thesis the impact of such mismatch on efficiency and supply inverter power sizing factor of WBC with SS topology has been studied. Three supply frequency updating techniques to keep in resonance either the transmitter stage or the receiver stage or the impedance seen from power supply have been investigated.
The thesis continues with the study of high power WBC systems which includes power supply architecture, core material and coil geometry. A review of different power supply architectures such as single phase with two stage and parallel topologies including their merits and demerits have been presented. Reviewing some paper on coil geometry, DD coil is found to be suitable for high power application. Using JMAG simulation tool, a transmitter track of three DD coils and a receiver with one DD coil has been analyzed when receiver is moving on the transmitting track.
Due to disfavor of ferrite as a core material for high-power WBC system, a varieties of different powdered magnetic materials have been considered here and compared in terms of saturated value of the magnetic flux density, magnetic properties -like dependency of their permeability on temperature, magnetic field strength and frequency-, power losses and cost. At last, two methods to model the WPT system have been considered. The methods model the system by considering the envelop of the signals.La ricarica wireless delle batterie a bordo dei veicoli elettrici, ottenuta utilizzando il trasferimento di potenza induttivo, offre vantaggi unici rispetto ai caricabatterie tradizionali. A causa dell'assenza di una connessione galvanica, il processo di ricarica non richiede alcuna interazione dell'utente né alcuna movimentazione di un componente meccanico. Per i sistemi di trasporto pubblico, ad esempio autobus o tram, questo rende possibile la cosiddetta carica di opportunità completamente automatizzata presso i depositi degli autobus, le corsie dei taxi, o ai semafori. I caricabatterie wireless sono costituiti da due stadi: uno stadio trasmittente e uno stadio di ricezione. Entrambi gli stadi includono bobine e condensatori, dimensionati per risuonare alla frequenza di alimentazione, e convertitori statici di potenza. La bobina del trasmettitore è interrata nel manto stradale, mentre la bobina ricevente è situata a bordo del veicolo. Sulla base della connessione dei condensatori risonanti sono possibili quattro topologie circuitali diverse che possono essere raggruppate in due principali: i) un condensatore in serie con la bobina di trasmissione con il condensatore lato ricevitore in serie o in parallelo costituisce le topologie SS e SP, rispettivamente, e ii) un condensatore in parallelo alla bobina di trasmissione con il condensatore della sezione ricevente in serie o in parallelo costituisce le topologie PS e PP, rispettivamente. Nella tesi queste topologie sono state studiate dettagliatamente in termini di efficienza, dimensionamento dell'invertitore di alimentazione e progetto delle bobine risonanti, e di comportamento nelle condizioni estreme di circuito aperto e di cortocircuito del ricevitore. Il circuito di conversione di potenza di un sistema per la ricarica wireless induttiva di un veicolo elettrico include un raddrizzatore a diodi nello stadio di ricezione per ottenere un bus di tensione in continua e utilizza differenti modi per caricare la batteria del veicolo. Le due soluzioni più diffuse eseguono la carica o direttamente attraverso il raddrizzatore a diodi oppure attraverso un chopper collegato in cascata ad esso. Queste due modalità sono state discusse e confrontate in termini di efficienza, di dimensionamento sia dell'invertitore di alimentazione, che delle bobine di trasmissione e ricezione, includendo nell’analisi la scelta della tensione ottima in ingresso al chopper. A causa dell'invecchiamento e dell'effetto termico, i parametri dei componenti reattivi di un circuito di ricarica wireless possono variare e questo fa sì che la frequenza di risonanza e la frequenza di alimentazione non siano perfettamente identiche. In questa tesi è stato studiato l'impatto che tale deviazione ha sull'efficienza e sul dimensionamento dell’invertitore in un sistema di ricarica wireless con topologia SS. Sono state studiate tre tecniche di adattamento della frequenza di alimentazione per mantenere in risonanza o lo stadio trasmittente o quello di ricezione oppure l’impedenza vista dall’alimentazione. La tesi prosegue con lo studio dei sistemi di ricarica wireless per elevate potenze che richiedono una specifica architettura di alimentazione, particolari materiali per la costruzione del nucleo magnetico, oltre ad una peculiare geometria delle bobine. E’ stata presentata una panoramica di diverse architetture di alimentazione come, ad esempio, le topologie monofase a due stadi e in parallelo, inclusi i loro pregi e svantaggi. Sulla base di un’accurata revisione della letteratura della geometria delle bobine, la geometria DD si è rivelata essere la più conveniente per le applicazioni di alta potenza. Utilizzando il codice agli elementi finiti JMAG, è stato simulato il comportamento di un sistema di ricarica wireless costituito da tre bobine di trasmissione e una bobina di ricezione, tutte di tipo DD. Poiché, date le sue caratteristiche, le ferriti non si prestano bene per sistemi ad alta potenza, sono state considerate altre tipologie di materiali magnetici. Sono state analizzate e confrontate diverse leghe amorfe in base all’induzione magnetica di saturazione, alle proprietà magnetiche, come la dipendenza della permeabilità dalla temperatura, dal campo magnetico applicato e dalla frequenza, alle perdite di potenza e al costo. Infine, sono stati considerati due metodi per modellizzare il WPT. I metodi modellizzano il sistema considerando l'inviluppo dei segnali.

Full textAbstract:
Wireless battery charging (WBC) is an attracting solution to promote electric vehicles (EVs) in the market, which may provide superior charging infrastructure and unlimited driving range. The most suitable technique to implement WBC is inductive power transfer (IPT) with a coupling established between two distant coils, one buried into the road and another installed in EV, and the power transferred from the buried coil to that onboard EV through a high-frequency oscillating magnetic flux. WBC can be carried out with EV that is either standing (while parked) or moving (on the road); the two WBC modes are termed static wireless charging (SWC) and dynamic wireless charging (DWC), respectively. However, this thesis focusses on the DWC, where an IPT track is buried into the road whilst the coil onboard EV, commonly termed pickup, remains coupled with the track to get power while moving on the road.
The in-moving vehicle charging has been researched and demonstrated by some institutes across the world using two possible track arrangements: stretched and lumped coil track. The former one is composed of a single elongated coil, much longer than the pickup size, and the later one is an arrangement of multiple coils placed one next to the other, the length of them being comparable to the pickup size. A lumped track permits activation/deactivation only of the coil interacting with a pickup. This ability is called segmentation and is very important for DWC to reduce the losses and to avoid exposing the people to electromagnetic radiations; therefore, a lumped track has been dealt with in this thesis.
The contactless power transfer at large airgap is possible with high frequency (in kHz) and high-magnitude current supply of the track coils; as increasing supply frequency improves power transfer efficiency. Apart from the supply characteristics and the coil dimensions, power transfer capabilities of a the system depend upon the coupling properties of the coil pairs, thus a pair polarized coils (also called DD coils) has been found more suitable for DWC due to its coupling merits at misalignment. Considering a lumped track composed of equally distant several DD coils, power and energy transfer to an EV moving on the track have been analyzed. Based on that, lumped track layout and its design procedure have been discussed in detail with an example of an EV.
Segmentation of a DWC track is very important function, as mentioned above, which can be obtained by various methods and one of them is using the impedance reflected into a track coil from the coupled pickup. In this way, four compensation topologies have been discussed to investigate their reflexive properties (resistance and reactance) when they are deployed in a pickup circuit. Summarizing the outcomes and comparing their behavior, two topologies have been found useful for the track segmentation. Considering them, further analysis has been done to obtain and discuss their performance figures.
This thesis also discusses about the power converters in both track side and pickup side circuit. The track side power converters include rectifier, power factor correction circuit and inverter, which extract power from the supply grid and transform into the appropriate form to realize efficient WBC. Converter arrangement in the pickup circuit includes rectifier and chopper to charger a battery using the received power.La ricarica della batteria senza fili (dall’inglese Wireless Battery Charging - WBC) è una soluzione attraente per la possibile diffusione dei Veicoli Elettrici (VE) nel mercato. Essa può fornire infrastrutture di ricarica migliori e un’ autonomia del veicolo praticamente illimitata. La tecnica più adatta per attuare il WBC è il trasferimento di potenza induttivo (Inductive Power Transfer - IPT), il quale sfrutta l’accoppiamento magnetico tra due bobine, una posizionata sotto il manto stradale e l’altra installata a bordo di un veicolo elettrico, e la potenza viene trasferita dalla bobina interrata a quella di bordo attraverso un flusso magnetico oscillante alta frequenza. Il WBC può essere effettuato con un VE fermo (parcheggiato) o in movimento sulla strada; le due modalità di WBC sono chiamate ricarica senza fili statica (Static Wireless Charging - SWC) e ricarica senza fili dinamica (Dynamic Wireless Charging - DWC), rispettivamente. Tuttavia, questa tesi si concentra sulla DWC, dove una bobina trasmittente, chiamata track, è interrata sotto la strada, mentre la bobina a bordo del VE, comunemente chiamata pickup, rimane accoppiata con il track per ricevere la potenza mentre il VE è in movimento. La ricarica di un VE in movimento è stata studiata e dimostrata da alcuni istituti di tutto il mondo i quali hanno adottato due differenti strutture di bobina trasmittente: track allungato e track concentrato. La prima struttura è formata da una singola bobina allungata, molto più lunga del pickup, mentre la seconda struttura è una disposizione di più bobine posizionate una dopo l’altra, la cui lunghezza è paragonabile alle dimensioni pickup. La struttura con track concentrato consente l'attivazione/disattivazione della sola bobina interagente con il pickup. Questa capacità è chiamata segmentazione ed è molto importante per DWC perché consente di ridurre le perdite e di evitare l'esposizione delle persone a radiazioni elettromagnetiche; di conseguenza, in questa tesi è stata trattata la soluzione con track concentrato. Il trasferimento della potenza senza fili con un elevato traferro è possibile solo con un’alta frequenza (dell’ordine dei kHz) ed un’alta intensità della corrente di alimentazione delle bobine del track; poiché l'aumento della frequenza di alimentazione migliora l'efficienza di trasferimento della potenza. Oltre alle caratteristiche di alimentazione e le dimensioni delle bobine, le capacità di trasferimento di potenza di un sistema dipendono dalle proprietà di accoppiamento delle bobine stesse, così una coppia di bobine polarizzate (chiamate anche bobine DD) è stata trovata essere la soluzione più adatta per il DWC grazie al suo elevato valore di accoppiamento quando track e pickup sono disallineati. Considerando un track concentrato composto da diverse bobine DD equamente distribuite, sono state analizzate la potenza e l’energia trasferite al VE in movimento. Sulla base di questo, la struttura del track concentrato e la sua procedura di progettazione sono stati discussi in dettaglio per un particolare caso di studio. Come detto precedentemente, la segmentazione del track è una funzione molto importante. Essa può essere ottenuta con vari metodi e uno di questi utilizza l'impedenza riflessa del pickup in una bobina del track. Così, quattro topologie di compensazione del circuito di pickup sono state investigate per studiarne le differenti impedenze riflesse. Riassumendo i risultati e confrontando il loro comportamento, solo due topologie sono state trovate utili per la segmentazione del track. Considerando quest’ultime, ulteriori analisi sono state fatte per ottenere e discutere le loro prestazioni. Questa tesi tratta anche i convertitori di potenza utilizzati sia nel track che nel pickup. I convertitori di potenza del track includono un raddrizzatore, un circuito di correzione del fattore di potenza (PFC) e un inverter, i quali sfruttano l’energia prodotta dalla rete di alimentazione e la convertono nella forma più appropriata per realizzare efficienti WBC. Nella bobina di pickup il circuito di condizionamento è formato dalla cascata di un raddrizzatore e un chopper che permettono di ricaricare la batteria di bordo utilizzando la potenza ricevuta.

This research investigates how to draw energy from a distant emanating and alternating (i.e., AC) magnetic source and deliver it to a battery (i.e., DC). The objective is to develop, design, simulate, build, test, and evaluate a CMOS charger integrated circuit (IC) that wirelessly charges the battery of a microsystem. A fundamental challenge here is that a tiny receiver coil only produces mV's of AC voltage, which is difficult to convert into DC form. Although LC-boosted diode-bridge rectifiers in the literature today extract energy from similar AC sources, they can do so only when AC voltages are higher than what miniaturized coils can produce, unless tuned off-chip capacitors are available, which counters the aim of integration. Therefore, rather than rectify the AC voltage, this research proposes to rectify the current that the AC voltage induces in the coil. This way, the system can still draw power from voltages that fall below the inherent threshold limit of diode-bridge rectifiers. Still, output power is low because, with these low currents, small coils can only extract a diminutive fraction of the magnetic energy available, which is why investing battery energy is also part of this research. Ultimately, the significance of increasing the power that miniaturized platforms can output is higher integration and functionality of micro-devices, like wireless microsensors and biomedical implants.

Full textAbstract:
This thesis deals with the Wireless Power Transfer (WPT) for the dynamic charging of Electric Vehicles (EVs). Dynamic WPT is an emerging technology that can accelerate the transition from conventional to electrical mobility. Dynamic Wireless Power Transfer Systems (WPTSs) exploit the principle of electromagnetic induction to power EVs during their motion without the need for a galvanic contact between the vehicles and a stationary supplying system. Since a portion of the power required by the EVs for the charging and for the propulsion is provided by an external grid, the size of the on-board batteries can be shrunk with the consequent benefits in terms of cost and weight of the EVs. An infrastructure of widespread public dynamic WPTSs can contribute to maintain the EVs always charged thus providing them with an ideal infinite range.
After a detailed introduction of the fundamental principles that govern the WPT technology and after a thorough description of a general WPTS, the focus of the thesis moves to dynamic WPTSs. The variations of the magnetic parameters caused by the EV movement make the study, the design, and the control of dynamic WPTSs very challenging. In the thesis, various dynamic WPTSs are studied under steady-state condition. This analysis shows that the LC compensation in the track side is particularly suited for such systems since it provides the track with the current source capability. This feature greatly simplifies the control and the power transfer regulation of dynamic WPTSs.
The attention of this thesis is focused mainly on the modeling and on the control of dynamic WPTSs. As regards the modeling, a novel method called Modulated Variable Laplace Transform (MVLT) is proposed. The method is used for the base band modeling of systems, such as dynamic WPTSs, where modulated quantities are involved. The accuracy of the MVLT is verified through the application of the method for the study of the dynamic of various circuits. In particular, MVLT method is adopted to find the dynamic model of an LC-compensated dynamic WPTS. With the aid of the obtained model the regulator that controls the track current of the system is designed. The performance of the regulator is tested by simulations, obtaining results in good agreement with the expected ones.
The thesis investigates also the dc/dc converter installed on-board the EVs responsible for the battery charging control. The operation of this converter is analyzed in conjunction with the type of compensating network used for the pickup. A novel topology for the pickup circuitry is proposed together with a new control strategy for the switch of the dc/dc converter. This topology allows for the pickup size reduction and it shows high performance in terms of efficiency.Questa tesi si occupa della tecnologia del trasferimento wireless di potenza (dall'inglese Wireless Power Transfer - WPT) per la ricarica dinamica dei Veicoli Elettrici (VE). Il trasferimento dinamico di potenza è una tecnologia innovativa che può accelerare la transizione da una mobilità convenzionale, basata su veicoli azionati da motore a combustione interna, verso una mobilità elettrica incentrata sui VE. I sistemi per il trasferimento wireless dinamico di potenza (dall'inglese Dynamic Wireless Power Transfer systems - DWPT systems) sfruttano il principio dell'induzione elettromagnetica per alimentare i VE mentre sono in movimento, senza la necessità di utilizzare un contatto galvanico tra i veicoli e un sistema di alimentazione stazionario. Poiché parte della potenza richiesta dai VE per la ricarica e per la propulsione è fornita da una rete elettrica esterna, le dimensioni delle batterie a bordo dei veicoli possono essere ridotte con i conseguenti benefici in termini di costo e peso dei VE. Una estesa infrastruttura di sistemi DWPT può contribuire a mantenere le batterie dei VE sempre cariche, consentendogli di avere un'autonomia idealmente illimitata. Dopo una dettagliata introduzione dei principi fondamentali che governano la tecnologia WPT e dopo un'accurata descrizione di un sistema WPT generico, il fulcro della tesi si sposta verso i sistemi DWPT. Le variazioni dei parametri magnetici causate dal movimento dei VE rendono lo studio, il dimensionamento e il controllo dei sistemi DWPT molto impegnativo. In questa tesi, vari sistemi DWPT sono studiati in condizione di regime stazionario. Questa analisi mostra che la compensazione del track fatta con una rete LC è particolarmente adatta per tali sistemi poiché essa conferisce al track la caratteristica di generatore di corrente. Questa proprietà semplifica di molto il controllo e la regolazione della potenza nei sistemi DWPT. L'attenzione di questa tesi è focalizzata principalmente sulla modellizzazione e sul controllo dei sistemi DWPT. Per quanto riguarda la modellizzazione, un nuovo metodo chiamato Modulated Variable Laplace Transform (MVLT) è presentato in questo lavoro. Questo metodo è usato per la modellizzazione dei sistemi, come ad esempio i sistemi DWPT, in cui sono coinvolte grandezze modulate. L'accuratezza del metodo MVLT è verificata attraverso la sua applicazione nello studio della dinamica di diversi circuiti. In particolare, il metodo MVLT è utilizzato per trovare il modello dinamico di un sistema DWPT in cui il track è compensato con una rete LC. Con l'ausilio del modello ottenuto viene progettato il regolatore che controlla la corrente del track del sistema. Le prestazioni di questo regolatore sono testate attraverso delle simulazioni, ottenendo risultati molto prossimi a quelli attesi. Nella tesi è studiato anche il convertitore dc/dc installato a bordo dei VE responsabile del controllo del processo di ricarica. Il funzionamento di questo convertitore è analizzato in modo congiunto con il tipo di compensazione del pickup. Una nuova topologia di circuito per il pickup è proposta assieme ad una nuova strategia di controllo per il convertitore dc/dc. Questa topologia permette una riduzione delle dimensioni del pickup e mostra elevate prestazioni in termini di efficienza.
