Résumé :

Two differential flatness-based bidirectional tracking robust controls for a DC/DC Buck converter-DC motor system are designed. To achieve such a bidirectional tracking, an inverter is used in the system. First control considers the complete dynamics of the system, that is, it considers the DC/DC Buck converter-inverter-DC motor connection as a whole. Whereas the second separates the dynamics of the Buck converter from the one of the inverter-DC motor, so that a hierarchical controller is generated. The experimental implementation of both controls is performed via MATLAB-Simulink and a DS1104 board in a built prototype of the DC/DC Buck converter-inverter-DC motor connection. Controls show a good performance even when system parameters are subjected to abrupt uncertainties. Thus, robustness of such controls is verified.

Résumé :

<span lang="EN-US">This paper proposes a new bidirectional step-up DC-DC converter, namely modified buck-boost DC-DC converter. The proposed DC-DC converter was derived from the conventional buck-boost DC-DC converter. Output voltage expression of the proposed converter was derived by considering the voltage drops across inductors and switching devices. The results have shown that with the same parameter of input LC filter, proposed DC-DC converter has lower conduction losses. Moreover, the proposed DC-DC converter has lower rated voltage of filter capacitor than the conventional boost DC-DC converter which lead to cost efficiency. Finally, a scaled-down prototype of laboratory experiment was used to verify its theoretical analysis.</span>

Résumé :

This paper is focusing on the stability analysis of the voltage mode control buck converter controlled by pulse-width modulation (PWM). Using two different approaches, the nonlinear phenomena are investigated in two terms, slow scale and fast scale bifurcation. A complete design-oriented approach for studying the stability of dc-dc power converters and its bifurcation has been introduced. The voltage waveforms and attractors obtained from the circuit simulation have been studied. With the onset of instability, the phenomenon of subharmonics oscillations, quasi-periodicity, bifurcations, and chaos have been observed

Résumé :

Switching Power Converters convert one form of power to another with high ef-ciency and accurate control.One of the most widely used DC-DC Converter is Buck Converter. Control is invariably required to maintain the output voltage/current in spite of variations in source/load. In order to design the controller and gain insight about the system a dynamic model needs to be developed. Modeling techniques widely used are state space averaging and PWM switch model. In this paper DC transformer modeling technique is used to develop the averaged model of the converter. One of the advantages of this model is that it can be implemented in Spice simulator using basic circuit elements. The same model can be used for time domain as well as frequency domain analysis. Analog type-II compensator is designed to compensate the system. Simulation and experimental results for start-up transient and load transient are shown to validate the model.

Résumé :

This article presents a novel impedance-source-based direct current (DC)-to-alternating current (AC)/DC converter (Z-Source DAD Converter). The Z-Source DAD converter converts the input DC voltage into AC or DC with buck or boost in the load voltage. This Z-Source DAD conversion circuit is a single-stage power conversion system. This converter circuit converts the input DC voltage into variable-magnitude output DC voltage or converts the DC voltage into a variable-magnitude output AC voltage. The higher voltage magnitude in boost mode can be controlled by controlling the shoot-through (ST) state timing of the converter. MATLAB-Simulink simulation and microcontroller-based hardware circuit results are presented to demonstrate power conversion with the buck and boost features of the Z-Source DAD converter for both types of output voltages. The simulation and experimental results show that the Z-Source DAD converter converts the given DC supply into AC or DC with buck or boost in the output load voltage.

Résumé :

This paper presents a technique to digitally control the output voltage of a DC-DC converter via a microcontroller. The voltage regulation and controlling were achieved utilizing an LM2596 buck converter. A digital potentiometer MCP41050 is utilized to smoothly control the regulated output DC voltage via the SPI digital protocol. The proposed design is manufactured and tested for various loads. This device is considered as a step-down voltage regulator capable of driving 3A load with high efficiency, excellent linearity, source-voltage variation, and load regulation. The results show that the system can control the output voltage with satisfactory performance and high accuracy. With various loads, the proposed system shows a mean square error of 0.015±0.037 volts tested with a regulated voltage of 5 volts. The efficiency improves from about 80% to around 91% at a 1 kΩ load. This design eliminates the possible errors that arise when manually varying the voltage of the buck converter; by means of using a microcontroller. Such a system ensures a proper digitally controlled output voltage with a better performance, which can be applied in various applications.

Résumé :

Abstract: The buck converter is a power electronic device which converts the higher level of input voltage to lower level of output voltage. For space applications, several tests were performed on direct current (DC) to (DC) converters to evaluate potential performance and reliability issues in space use of DC to DC converters and to determine if the use of electromagnetic interference (EMI) filters mitigates concerns observed during tests. Test findings reported here include those done up until January–June 2022. Tests performed include efficiency, regulation, load regulation, power consumption with inhibit on, load transient response, synchronization, and turn-on tests. Some of the test results presented here span the thermal range -20°C to 55°C. Lower range was extended to -40°C in some tested converters.

Résumé :

DC chopper jenis buck dengan beberapa aplikasi telah banyak dibuat. Namun dalam penelitian tersebut hanya menggunakan tegangan masukan yang dturunkan terlebih dahulu oleh trafo step down. Selain itu, dalam beberapa penelitian dengan DC chopper buck tidak pernah memperhitungkan seberapa besar pengaruh efek parasitik terhadap tegangan keluaran yang dibutuhkan. Komponen pensaklaran yang digunakan dalam beberapa penelitian juga tidak dibahas secara mendalam. Dari beberapa topologi konverter arus searah, konverter jenis buck dipilih karena konverter ini menghasilkan tegangan keluaran yang memiliki nilai maksimal sama dengan tegangan masukan Selain itu, buck converter memiliki efisiensi yang tinggi dan riak pada tegangan keluaran yang rendah. Dalam penelitian ini akan dibahas respon DC Chopper Buck dengan catu daya utama tegangan AC jala-jala satu fasa yang disearahkan yang meliputi tegangan masukan, arus masukan, tegangan keluaran, arus keluaran, dan efisiensi. Berdasarkan hasil pengujian, tegangan yang digunakan untuk mensuplai DC Chopper buck ini sebesar 300 Volt dengan variasi beban resistif dan beban dominan induktif. Variasi beban resistif yang digunakan yaitu 40Ω, 100Ω, dan 300Ω. Efisiensi yang dihasilkan ketika diberi beban resistif 40Ω dengan tegangan 30V-210V yaitu sebesar 62,60%-98,08%, beban 100Ω sebesar 42,05%-97,18%, sedangkan pada beban 300Ω efisiensi yang dihasilkan sebesar 37,32%-90,90%.

Résumé :

In the era of modern industrial development, power electronics equipment has been developed aggressively and brought dc system again in power utilization to use clean energy resources like solar array, fuel cell, wind generator, etc. Since the past decade, power electronics equipment has become very popular; hence, the switch-mode converter requirement is increasing rapidly day by day in applications like communication power supply, space crafts, hybrid electric vehicles, micro-grid and nano-grids. Among the various available configurations of converters, Multi-Input DC/DC converters became more and more popular in power electronics field, especially, for provide interface of various renewable energy sources and deliver regulated power to several loads. In this article, a PVSC type Buck Buck-Boost Dual-Input DC- DC Converter (DIDC) is designed and modelled for DC grid application. The proposed converter is driven with two renewable energy sources PV cell and a battery having different amplitudes which can able to deliver the power from source to load individually or simultaneously. DIDC tropology is simply configured with two passive elements L, C, diodes D1 D2 and switches S1 , S2. The Dual-Input DC-DC Converter suitability is validated by carrying out simulations in different modes of operation. The de-centralized PID controller is designed for voltage and current loop controller to ensure the DC output voltage of 48 V, load current of 4.8 A and power of 230W. The Stability of the closed-loop converter is also verified under all possible source and load disturbance conditions. The simulations and analysis of the proposed converter are carried out using MATLAB and PSIM software.

Résumé :

This paper has two aims. The first is to develop a robust hierarchical tracking controller for the DC/DC Buck-Boost–inverter–DC motor system. This controller considers a high level control for the inverter–DC motor subsystems and a low level control for the DC/DC Buck-Boost converter subsystem. Such controls solve the tracking task associated with the angular velocity of the motor shaft and the output voltage of the converter, respectively, via the differential flatness approach. The second aim is to present a comparison of the robust hierarchical controller to a passive controller. This, with the purpose of showing that performance achieved with the hierarchical controller proposed in this paper, is better than the one achieved with the passive controller. Both controllers are experimentally implemented on a prototype of the DC/DC Buck-Boost–inverter–DC motor system by using Matlab-Simulink along with the DS1104 board from dSPACE. According to experimental results, the proposal in the present paper achieves a better performance than the passive controller.

Résumé :

Buck-boost DC–DC converters are useful as DC grid interfaces for renewable energy resources. In the classical buck-boost converter, output voltages smaller than the input voltage (the buck region) are observed for duty cycles between 0 and 0.5. Several recent buck-boost converters have been designed to present higher voltage gains. Nevertheless, those topologies show a reduced duty-cycle range, leading to output voltages in the buck region, and thus require the use of very low duty cycles to achieve the lower range of buck output voltages. In this work, we propose a new buck-boost DC-DC converter that privileges the buck region through the extension of the duty-cycle range, enabling buck operation. In fact, the converter proposed here allows output voltages below the input voltage even with duty cycles higher than 0.6.

Résumé :

This paper presents the design of a Fuzzy logic controller for a DC-DC step-down converter. Buck converters are step-down regulated converters which convert the DC voltage into a lower level standardized DC voltage. The buck converters are used in solar chargers, battery chargers, quadcopters, industrial and traction motor controllers in automobile industries etc. The major drawback in buck converter is that when input voltage and load change, the output voltage also changes which reduces the overall efficiency of the Buck converter. So here we are using a fuzzy logic controller which responds quickly for perturbations, compared to a linear controllers like P, PI, PID controllers. The Fuzzy logic controllers have become popular in designing control application like washing machine, transmission control, because of their simplicity, low cost and adaptability to complex systems without mathematical modeling So we are implementing a fuzzy logic controller for buck converter which maintains fixed output voltage even when there are fluctuations in supply voltage and load. The fuzzy logic controller for the DC-DC Buck converter is simulated using MATLAB/SIMULINK. The proposed approach is implemented on DC-DC step down converter for an input of 230V and we get the desired output for variations in load or references. This proposed system increases the overall efficiency of the buck converter.

Résumé :

The paper presents a new methodology for optimizing the design of DC-DC converters. The magnitudes that we take into account are efficiency, ripples, bandwidth, and RHP zero placement. We apply a geometric programming approach, because the variables are positives and the constraints can be expressed in a posynomial form. This approach has all the advantages of convex optimization. We apply the proposed methodology to a boost converter. The paper also describes the optimum designs of a buck converter and a synchronous buck converter, and the method can be easily extended to other converters. The last example allows us to compare the efficiency and bandwidth between these optimal-designed topologies.

Résumé :

The use of fuel cells in DC microgrids has been receiving a lot of attention from researchers and industry since both technologies can deliver clean energy with little to no environmental impact. To effectively integrate fuel cells in DC microgrids, a power converter that can equate the fuel cell’s voltage with the DC microgrid’s reference voltage is required. Based on the typical output voltages of fuel cells, buck-boost topologies are commonly used in this type of application. A variety of DC-DC buck-boost topologies, showing distinctive merits and drawbacks, are available in the literature. Therefore, this paper compiles, compares and describes different DC-DC buck-boost topologies that have been introduced in the literature over the past few years. Additionally, some design considerations are addressed, and future work is proposed.

Résumé :

In this paper, a new transformerless buck-boost converter is presented. The voltage gain of the converter is higher than the classic boost converter, classic buck-boost converter, CUK and SEPIC converters. The proposed converter advantage is buck-boost capability. The proposed converter topology is simple; therefore, the converter control is simple. The converter has one main switch. Hence, the switch with low switching and conduction losses can be used. The stress of the main switch is low; therefore, switch with low on-state resistance can be selected. The principles of the converter and mathematic analyses are presented. The validity of the accuracy of calculations is verified by the experimental results.

Résumé :

This study provides a step-by-step analysis of closed-loop parametric system identification for DC-DC buck converter. In closed-loop parametric identification, input–output experimental data are used to estimate the transfer function coefficients of DC-DC buck converter. For system identification purpose, a high-frequency perturbation signal is injected in to the closed-loop system which acts as an input signal for identification experiment. Different input–output models such as Auto-Regressive eXogenous, Auto-Regressive Moving Average with eXogenous, output error, and Box–Jenkins are used to model the converter structure and prediction error method is used to estimate the parameters. Model validation schemes are used to validate the estimated model. Simulation and experimental analysis have been provided to validate the results obtained.

Résumé :

A new Posicast compensated hybrid controller for the DC-DC Buck converter is investigated. Posicast is a feed forward compensator, which eliminates the overshoot in the step response of a lightly damped system. However, the traditional method is sensitive to variations in natural frequency. The new method described here reduces this undesirable sensitivity by using Posicast within the feedback loop. Design of the Posicast function is independent of computational delay. The new controller results in a lower noise in the control signal, when compared to a conventional PID controller.

Résumé :

This paper proposes a universal converter that is capable of operating in three modes for generating positive dc voltage, negative dc voltage, and sinusoidal ac voltage. By controlling the duty-cycle of two half-bridges, an inductor is operated at a high frequency to control the voltage across two film capacitors that constitute a dual-buck-boost converter. Two additional half-bridges operating at a fixed state or line frequency are used to select the mode of operation. Compared to the latest universal converter in the recent literature, the proposed topology has the same switch count while reducing the number of conducting switches for inductor current and reducing the number of switches operating at high frequency. The operation of the proposed dual-buck-boost dc–dc/ac universal converter is analyzed. Experimental results are presented for validation. The power conversion efficiency of the 100 W experimental prototype modeled in PLECS is approximately 98%.
