Human jumping motion includes stance phase, flight phase and landing impact phase. Jumping robot belongs to a variable constraints system because every phase has different constraint conditions. An unified dynamics equation during stance phase and flight phase is established based on floated-basis space. Inertia matching is used to analyze actuator/gear systems and select the optimum gear ratio based on the transmission performance between the torque produced at the actuator and the torque applied to the load. Load matching is an important index which affects jumping performance and reflects the capability of supporting a weight or mass. It also affects the distributing of the center of gravity (COG). Regarding jumping robot as a redundant manipulator with a load at end-effector, inertia matching can be applied to optimize load matching for jumping robot. Inertia matching manipulability and directional manipulability are easy to analyze and optimize the load matching parameters. A 5th order polynomial function is defined to plan COG trajectory of jumping motion, taking into account the constraint conditions of both velocity and acceleration. Finally, the numerical simulation of vertical jumping and experimental results show inertia matching is in direct proportion to jumping height, and inertia matching manipulability is a valid method to load matching optimization and conceptual design of robot.

The decomposing method of wideband microwave high power microstrip loads design is proposed in this paper with purpose of matching quality improving. Multiple extension of multistage load bandwidth is provided by using of external matching circuit and internal matching inductive elements. The maximum reachable bandwidth of multistage load is estimated and optimal values of mathing circuit elements are founded on basis of equivalent lumped scheme. The topology of microstrip two-stage high power microwave load is developed and its frequency response, calculated via numeric electrodynamic modelling method is outlined in the paper.

The quantitative evaluation of cluster wind power output volatility and source-load timing matching is vital to the planning and operation of the future power system dominated by new energy. However, the existing volatility evaluation methods of cluster wind power output do not fully consider timing volatility, or are not suitable for small sample data scenarios. Meanwhile, the existing source-load timing matching evaluation indicator ignores the impact of wind power permeability on the timing matching degree between wind power output and load. Therefore, the authors propose quantitative evaluation methods of cluster wind power output volatility and source-load timing matching in regional power grid. Firstly, the volatility-based smoothing coefficient is defined to quantitatively evaluate the smoothing effect of wind-farm cluster power output. Then, the source-load timing matching coefficient considering wind power permeability is proposed to quantitatively evaluate the timing matching degree of regional wind power output and load, and the corresponding function model of volatility-based smoothing coefficient and source-load timing matching coefficient is established. Finally, the validity and applicability of the proposed methods are verified by MATLAB software based on the actual power output of 10 wind farms and actual grid load in a certain grid dispatching cross-section of northeast China. The results demonstrated that the proposed volatility-based smoothing coefficient can accurately represent the smoothing effect of wind farm cluster power output while maintaining the volatility continuity of wind power output time series and without affect from the data sample size. The source-load timing matching coefficient can accurately characterize the difference in the timing matching degree between wind power output and grid load under different wind power permeability and the influence degree on grid load.

The matching of cognitive load and working memory is the key for effective learning, and cognitive effort in the learning process has nervous responses which can be quantified in various physiological parameters. Therefore, it is meaningful to explore automatic cognitive load pattern recognition by using physiological measures. Firstly, this work extracted 33 commonly used physiological features to quantify autonomic and central nervous activities. Secondly, we selected a critical feature subset for cognitive load recognition by sequential backward selection and particle swarm optimization algorithms. Finally, pattern recognition models of cognitive load conditions were constructed by a performance comparison of several classifiers. We grouped the samples in an open dataset to form two binary classification problems: (1) cognitive load state vs. baseline state; (2) cognitive load mismatching state vs. cognitive load matching state. The decision tree classifier obtained 96.3% accuracy for the cognitive load vs. baseline classification, and the support vector machine obtained 97.2% accuracy for the cognitive load mismatching vs. cognitive load matching classification. The cognitive load and baseline states are distinguishable in the level of active state of mind and three activity features of the autonomic nervous system. The cognitive load mismatching and matching states are distinguishable in the level of active state of mind and two activity features of the autonomic nervous system.

This dissertation comprises two distinct topics concerning photovoltaics: studying solar electrolyzer performance with a practical consideration of their design and operation, and extrinsic p-type doping in thin-film CdTe solar cells using Sb for improved voltage output.

Solar fuel generation via water and CO₂ reduction using photovoltaics has witnessed considerable growth since the identification of photocatalysis four decades ago. Numerous photovoltaic-driven electrochemical cells (PV-ECs) and photoelectrochemical cells (PECs) with efficiencies reaching 30% for H₂O reduction and 10% for CO₂ reduction have been reported. We will discuss the many benefits of a PV-EC system over the PEC approach. This dissertation discusses the implementation of a high-efficiency PV-EC using silicon solar cells and a flow-cell CO₂ electrolyzer (in collaboration with Prof. Feng Jiao group from UDel’s Center for Catalytic Science and Technology). With 25 cm² electrode area, this is the largest CO₂ electrolysis device yet reported that exhibited > 6.5% efficiency at operating currents in excess of 1A. The development of a model to optimize the coupling of such devices and to simulate annual field performance will be presented. Improvement in fuel generation by > 20% is demonstrated by employing power electronic devices to continuously optimize the PV-EC operating point for maximum power coupling despite variable sunlight and temperature.

Polycrystalline thin-film CdTe/CdS heterojunction solar cells are the leading commercial competitor to c-Si solar modules. While having demonstrated good performance at low cost and large scale, the potential to exceed 25% efficiency by enhancing open circuit voltage (Voc), from present ~0.9V to the near-ideal 1.1 V, is possible with carrier concentrations exceeding 5 × 10¹⁶ cm^–3 while retaining bulk minority carrier lifetime > 10 ns. State-of-the-art intrinsic CdTe solar cells, wherein n- or p-type doping is achieved through native point defect (V_Cd) control during film growth, are limited to acceptor concentration levels of < 10¹⁵ cm^–3. Bridging the Voc gap through extrinsic doping of polycrystalline CdTe films with Sb during film growth using vapor transport deposition technique is examined. Applying device characterization and analysis techniques to cells processed with different post-growth device treatments for dopant activation shows where optimization effort is needed. Admittance and current-voltage measurements indicate that despite significant improvement in acceptor density (up to 3 × 10¹⁵ cm^–3), Voc is limited to < 600 mV due to increased defect density and thus reduced minority carrier lifetime.

Atualmente, o uso de grandes ontologias em diversos domínios do conhecimento está aumentando. Uma vez que estas ontologias podem apresentar sobreposição de conteúdo, a identificação de correspondências entre seus conceitos se torna necessária. Esse processo é chamado de Matching de Ontologias (MO). Um dos maiores desafios do matching de grandes ontologias é o elevado tempo de execução e o excessivo consumo de recursos de computacionais. Assim, para melhorar a eficiência, técnicas de particionamento de ontologias e paralelismo podem ser empregadas no processo de MO. Este trabalho apresenta uma abordagem para o Matching de Ontologias baseado em Particionamento e Paralelismo (MOPP) que particiona as ontologias de entrada em subontologias e executa as comparações entre conceitos em paralelo, usando o framework MapReduce como solução programável. Embora as técnicas de paralelização possam melhorar a eficiência do processo de MO, essas técnicas apresentam problemas referentes ao desbalanceamento de carga. Por essa razão, o presente trabalho propõe ainda duas técnicas para balanceamento de carga (básica e refinada) para serem aplicadas junto à abordagem MOPP, a fim de orientar a distribuição uniforme das comparações (carga de trabalho) entre os nós de uma infraestrutura computacional. O desempenho da abordagem proposta é avaliado em diferentes cenários (diferentes tamanhos de ontologias e graus de desbalanceamento de carga) utilizando uma infraestrutura computacional e ontologias reais e sintéticas. Os resultados experimentais indicam que a abordagem MOPP é escalável e capaz de reduzir o tempo de execução do processo de MO. No que diz respeito às técnicas de balanceamento de carga, os resultados obtidos mostram que a abordagem MOPP é robusta, mesmo em cenários com elevado grau de desbalanceamento de carga, com a utilização da técnica refinada de balanceamento de carga.
Currently, the use of large ontologies in various áreas of knowledge is increasing. Since, these ontologies can present contents overlap, the identification of correspondences among their concepts is necessary. This process is called Ontologies Matching (OM). One of the major challenges of the large ontologies matching is the high execution time and the computational resources consumption. Therefore, to get the efficiency better, partition and parallel techniques can be employed in the MO process. This work presents a Partition-Parallelbased Ontology Matching (PPOM) approach which partitions the input ontologies in subontologies and executes the comparisons between concepts in parallel, using the framework MapReduce as a programmable solution. Although the parallel techniques can get the MO efficiency process better, these techniques present problems concerning to the load imbalancing. For that reason, our work has proposed two techniques to the load balancing - the basic and the fine-grained one - which are supposed to be applied together with the PPOM approach, in order to orientate the uniform distribution of the comparisons (workload) between the nodes of a computing infrastructure. The performance of the proposed approach is assessed in different settings (different sizes of ontologies and degrees of load imbalancing) using a computing infrastructure and real and synthetic ontologies. The experimental results have indicated that the PPOM approach is scalable and able to reduce the OM process execution time. Referring to the load balancing techniques, the obtained results have shown that the PPOM approach is robust, even in settings with a high load imbalancing, with the fine-grained load balancing technique.

High-frequency and large amplitude current is a driving requirement for applications such as induction heating, wireless power transfer, power amplifier for magnetic resonant imaging, electronic ballasts, and ozone generators. Voltage-fed resonant inverters are normally employed, however, current-fed (CF) resonant inverters are a competitive alternative when the quality factor of the load is significantly high. The input current of a CF resonant inverter is considerably smaller than the output current, which benefits efficiency. A simple, parallel resonant tank is sufficient to create a high-power sinusoidal signal at the output. Additionally, input current is limited at the no-load condition, providing safe operation of the system. Drawbacks of the CF resonant inverter are associated with the implementation of the equivalent current source. A large input inductor is required to create an equivalent dc current source, to reduce power density and the bandwidth of the system. For safety, a switching stage is implemented using bidirectional voltage-blocking switches, which consist of a series connection of a diode and a transistor. The series diode experiences significant conduction loss because of large on-state voltage. The control of the output current amplitude for constant-frequency inverters requires a pre-regulation stage, typically implemented as a cascaded hard-switched dc/dc buck converter. The pre-regulation also reduces the efficiency. In this dissertation, a variety of CF resonant inverters with two input inductors and two grounded switches are investigated for an inductive-load driver with loaded quality factor larger than ten, constant and high-frequency (~500 kHz) operation, high reactive output power (~14 kVA), high bandwidth (~100 kHz), and high efficiency (over 95 %). The implementation of such system required to question the fundamental operation of the CF resonant inverter. The input inductance is reduced by around an order of magnitude, ensuring sufficient bandwidth, and allowing rich harmonic content in the input current. Of particular importance are fundamental and second harmonic components since they influence synchronization of the zero-crossing of the output voltage and the turn-on of the switches. The synchronization occurs at a particular frequency, termed synchronous frequency, and it allows for zero switching loss in the switches, which greatly boosts efficiency. The synchronous conditions were not know prior this work, and the dependence among circuit parameters, input current harmonics, and synchronous frequency are derived for the first time. The series diode of the bidirectional switch can reduce the efficiency of the system to below 90 %, and has to be removed from the system. The detrimental current-spikes can occur if the inverter is not operated in synchronous condition, such as in transients, or during parametric variations of the load coil. The resistance of the load coil has a wide variance, five times or more, while the inductance changes as well by a few percent. To accommodate for non-synchronous conditions, a low-loss current snubber is proposed as a safety measure to replace lossy diodes. The center-piece of the dissertation is the proposal of a two-phase zero-voltage switching buck pre-regulator, as it enables fixed frequency and synchronous operation of the inverter under wide parametric variations of the load. The synchronous operation is controlled by phase-shifting the switching functions of the pre-regulator and inverter. The pre-regulator reduces the dc current in the input inductors, which is a main contributor to current stress and conduction losses in the inverter switches. Total loss of the inverter switches is minimized since no switching loss is present and minimal conduction losses are allowed. The dc current in the input inductors, once seen as a means to transfer power to load, is now contradictory perceived as parasitic, and the power is transferred to the load using a fundamental frequency harmonic! The input current to the resonant tank, previously designed to be a square-wave, now resembles a sine-wave with very rich harmonic content. Additionally, the efficiency of the pre-regulator at heavy-load condition is improved by ensuring ZVS for with an additional inductive tank. The dissertation includes five chapters. The first chapter is an introduction to current-fed resonant inverters, applications, and state-of-the-art means to ensure constant frequency operation under load's parametric variations. The second chapter is dedicated to the optimization of the CF resonant inverter topology with a dc input voltage, two input inductors, and two MOSFETs. The topology is termed as a boost amplifier. If the amplifier operates away from the synchronous frequency, detrimental current spikes will flow though the switches since the series diodes are eliminated. Current spikes reduce the efficiency up to few percent and can create false functioning of the system. Operation at the synchronous frequency is achieved with large, bulky, input inductors, typically around 1-2 mH or higher, when the synchronous frequency follows the resonant frequency of the tank at 500 kHz. The input inductance cannot be reduced arbitrarily to meet the system bandwidth requirement, since the synchronous frequency is increased based on the inductance value. The relationship between the two (input inductance and the synchronous frequency) was unknown prior this work. The synchronous frequency is determined to be a complicated mathematical function of harmonic currents through the input inductors, and it is found using the harmonic decomposition method. As a safety feature, a current snubber is implemented in series with the resonant tank. Snubber utilizes a series inductance of cable connection between the tank and the switching stage, and it is more efficient than the previously employed series diodes. Topology optimization and detailed design procedure are provided with respect to efficiency and system dynamics. The mathematics is verified by a prototype rated at 14 kVA and 1.25 kW. The input inductance is reduced by around an order of magnitude, with the synchronous frequency increase of 2 %. The efficiency of the power amplifier reached 98.5 % and might be improved further with additional optimization. Silicon carbide MOSFETs are employed for their capability to operate efficiently at high frequency, and high temperature. The third chapter is dedicated to the development of the boost amplifier's large signal model using the Generalized State-space Averaging (GSSA) method. The model accurately predicts amplifier's transient and steady-state operation for any type of input voltage source (dc, dc with sinusoidal ripple, pulse-width modulated), and for either synchronous or non-synchronous operating frequency. It overcomes the limitation of the low-frequency model, which works well only for dc voltage-source input and at synchronous frequency. As the measure of accuracy, the zero-crossing of the resonant voltage is predicted with an error less than 2° over a period of synchronous operation, and for a range of interest for input inductance (25 μH – 1000 μH) and loaded-quality factor (10 – 50). The model is validated both in simulation and hardware for start-up transient and steady-state operation. It is then used in the synthesis of modulated output waveforms, including Hann-function and trapezoidal-function envelopes of the output voltage/current. In the fourth chapter, the GSSA model is employed in development of the PWM compensation method that ensures synchronous operation at constant frequency for the wide variation of the load. The boost amplifier is extended with a cascaded pre-regulator whose main purpose is to control the output resonant voltage. The pre-regulator is implemented as two switching half-bridges with same duty-cycle and phase-shift of 180°. The behavior of the cascaded structure is the same as of the buck converter, so the half-bridges are named buck pre-regulators. ZVS operation is ensured by putting an inductive tank between the half-bridges. Each output of half-bridges is connected to each of input inductors of the boost to provide the PWM excitation. Using the GSSA model, the synchronous condition and control laws are derived for the amplifier. Properties of the current harmonics in the input inductors are well examined. It is discovered that the dc harmonic, once used to transfer power, is unwanted (parasitic) since it increases conduction loss in switches of the boost. A better idea is to use the fundamental harmonic for power transfer, since it does not create loss in the switches. Complete elimination of the dc current is not feasible for constant frequency operation of the amplifier since the dc current depends on the load coil's resistance. However, significant mitigation of around 55 % is easily achievable. The proposed method improves significantly the efficiency of both the buck pre-regulator and the boost. Synchronous operation is demonstrated in hardware for fixed switching frequency of 480 kHz, power level up to 750 W, input voltage change from 300 V to 600 V, load coil's resistance change of three times, and load coil's inductance change of 3.5 %. Measured efficiency is around 95 %, with a great room for improvements. Chapter five summarizes key contributions and concludes the dissertation.

In this thesis we introduce a two-way Doherty amplifier architecture with multiple feedbacks for digital predistortion based on impedance-inverting directional coupler (transcoupler). The tunable two-way Doherty amplifier with a tuned circulator-based impedance inverter is presented. Compact N-way Doherty architectures that subsume impedance inverter and offset line functionality into output matching networks are derived. Comprehensive N-way Doherty amplifier design and analysis techniques based on load-pull characterization of active devices and impedance modulation effects are developed. These techniques were then applied to the design of a two-way Doherty amplifier and a three-way Doherty amplifier which were manufactured and their performance measured and compared to the amplifier performance specifications and simulated results.

Induction heating has become a popular alternative to other heat sources for stovetop cooking applications due to performance, efficiency, control response, and safety. The main drawback is that extreme difficulty is encountered when trying to head low-resistivity, non-ferromagnetic metals such as aluminum and copper, which are commonly used for cookware in several societies. The lack of ferromagnetic properties, resulting in no hysteresis dissipation, and low resistivity of such metals results in an impractically low resistance reflected through the work coil. The resultant impedance complicates inverter design, as it is too low to be efficiently driven with conventional inverter topologies. The magnitudes of current involved in exciting this impedance also severely impact the efficiency of the coil and resonant components, requiring extreme care in coil design. This work explores various techniques that have been proposed and/or applied to efficiently heat low-resistivity cookware and the associated limitations. A transformer-coupled series-load-resonant topology driven by a full-bridge inverter is proposed as a means of efficiently heating aluminum cookware within practical design constraints. The experimental circuit is built and successfully tested at an output power of 1.66kW. The procedure of optimizing the work coil for improved efficiency is also presented along with the procedure of measuring coil efficiency. An improved circuit incorporating switch voltage detection to guarantee zero-voltage switching is then built in order to overcome limitations of this design.

Elements of Induction Heating: Design, Control, and Applications discusses the principles of electromagnetic induction and the setup and use of induction heating processes and equipment. The first few chapters cover the theory of induction heating and the factors that must be considered when selecting and configuring components for a given application. As the text explains, the frequency required for efficient heating is determined by the geometry of the coil, the properties, size, and shape of the workpiece, and the need to maintain adequate skin effect. It also depends on proper tuning and load matching, which is explained as well. Subsequent chapters discuss the use of external cooling, temperature sensing, and power-timing devices, the fundamentals of process control, the role of flux concentrators, shields, and susceptors, and the integration of material handling equipment. The book also covers coil design and fabrication and explains how induction heating systems can be tailored for specific applications such as billet and bar heating, surface hardening, pipe welding, tin reflow, powder metal sintering, and brazing, and for curing adhesives and coatings.

AbstractIn EMC, it is essential to understand the concept of transmission lines and when to apply it. Because once a signal interconnection line exceeds a critical length lcritical [m], impedance matching ( $$ \underline {Z}_{source}$$ Z ̲ s o u r c e , $$ \underline {Z}_{line}$$ Z ̲ l i n e , $$ \underline {Z}_{load}$$ Z ̲ l o a d ) must be considered to prevent reflections and ringing, thus preventing unwanted radiated emissions and bad signal quality—a signal integrity topic.This chapter introduces transmission lines and their most important properties.

The variability of wind and solar energy technologies is perceived as a major obstacle to employing otherwise abundant renewable energy resources. Based on the available geographically dispersed data for the continental U.S. (excluding Alaska), we analyze to what extent the geographic diversity of these resources can offset their variability. We determine the best match to loads that can be achieved with wind power and photovoltaics with no transmission limitations. Without storage, wind and PV can meet up to 50% of loads in Western US. It is beneficial to build more wind than PV mostly because the wind contributes at night. When storage is available, the optimal mix has almost 75% as much nominal PV capacity as wind, with the PV energy contribution being 32% of the electricity produced from wind. With only 40 GW of storage (twice the pumped hydro storage capacity that already exists in the continental US), up to 82% of the load can be matched with wind and PV, while at the same time curtailing less than 10% of the renewable energy throughout the year.
