Abstract:
This paper presents a full-bridge active-clamp forward-flyback (FBACFF) converter with an integrated transformer sharing a single primary winding. Compared to the conventional active-clamp-forward (ACF) converter, the proposed converter has low voltage stress on the primary switches due to its full-bridge active-clamp structure, which can leverage high performance Silicon- metal–oxide–semiconductor field-effect transistor (Si-MOSFET) of low voltage rating and low channel resistance. Integrating forward and flyback operations allows the proposed converter to have much lower primary root mean square (RMS) current than the conventional phase-shifted-full-bridge (PSFB) converter, while covering wide input/output voltage range with duty ratio over 0.5. The proposed integrated transformer reduces the transformer conduction loss and simplify the secondary structure of the proposed converter. As a result, the proposed converter has several advantages: (1) high heavy load efficiency, (2) wide input voltage range operation, (3) high power density with the integrated transformer, and (4) low cost. The proposed converter is a very promising candidate for applications with wide input voltage range and high power, such as the low-voltage DC (LDC) converter for eco-friendly vehicles.

Abstract:
Recently, the integrated On-Board Charger (OBC) combining an OBC converter with a Low-Voltage DC/DC Converter (LDC) has been considered to reduce the size, weight and cost of DC-DC converters in the EV system. This paper proposes a new integrated OBC converter with V2G (Vehicle-to-Grid) and auxiliary battery charge functions. In the proposed integrated OBC converter, the OBC converter is composed of a bidirectional full-bridge converter with an active clamp circuit and a hybrid LDC converter with a Phase-Shift Full-Bridge (PSFB) converter and a forward converter. ZVS for all primary switches and nearly ZCS for the lagging switches can be achieved for all the operating conditions. In the secondary side of the proposed LDC converter, an additional circuit composed of a capacitor and two diodes is employed to clamp the oscillation voltage across rectifier diodes and to eliminate the circulating current. Since the output capacitor of the forward converter is connected in series with the output capacitor of the auxiliary battery charger, the energy from the propulsion battery can be delivered to the auxiliary battery during the freewheeling interval and it helps reduce the current ripple of the output inductor, leading to a smaller volume of the output inductor. A 1 kW prototype converter is implemented to verify the performance of the proposed topology. The maximum efficiency of the proposed converter achieved by the experiments is 96%.

Abstract:
A bidirectional three-level soft switching circuit topology is proposed and implemented for medium voltage applications such as 750 V dc light rail transit, high power converters, or dc microgrid systems. The studied converter is constructed with a three-level diode-clamp circuit topology with the advantage of low voltage rating on the high-voltage side and a full-bridge circuit topology with the advantage of a low current rating on the low-voltage side. Under the forward power flow operation, the three-level converter is operated to regulate load voltage. Under the reverse power flow operation, the full-bridge circuit is operated to control high-side voltage. The proposed LLC resonant circuit is adopted to achieve bidirectional power operation and zero-voltage switching (ZVS). The achievability of the studied bidirectional ZVS converter is established from the experiments.

Abstract:
The main theme of this paper is to present the laboratory course modular design for learning and hands-on magnetic components in power converters. The objective of the course is to give the students to model the converters, realize magnetic components and test the implemented converters via the hands-on work in order to improve practical skills of students under the insufficiency of regular course training. This designed course is based upon the modular concept of five modules in common use which include forward converter, flyback converter, push-pull converter, half-bridge converter and full-bridge converter. The controllers for these converter modules include voltage mode control and peak current mode control. The specifications for each converter module are the same, 48V/12V, 60W and 100 kHz of switching frequency. The designed modular curriculum has been applied to the Industrial Technology Research and Development Master (ITRDM) Program sponsored by the industry and government. And excellent acknowledgment from students is received for providing practical training and covering the wide range of magnetic components in power conversion applications.

Abstract:
A bidirectional resonant converter is presented and verified in this paper for an electric vehicle battery charger/discharger system. The presented circuit can achieve forward and backward power operation, low switching losses on active devices, and wide output voltage operation. The circuit structure of the presented converter includes two resonant circuits on the primary and secondary sides of an isolated transformer. The frequency modulation approach is adopted to control the studied circuit. Owing to the resonant circuit characteristic, active devices for both forward (battery charge) and backward (battery discharge) power operation can be turned on at zero voltage switching. In order to implement a universal battery charger for different kinds of electric vehicle applications, the DC converter is demanded to have a wide output voltage range capability. The topology morphing between a full bridge resonant circuit and half bridge resonant circuit is selected to obtain high- and low-output voltage range operations so that the 200–500 V output voltage range is realized in the presented resonant converter. Compared to the conventional bidirectional converters, the proposed can be operated under a wide voltage range operation. In the end, a 1 kW laboratory prototype circuit is built, and experiments are provided to demonstrate the validity and performance of the presented bidirectional resonant converter.

Abstract:
In order to achieve a good dynamical response of a full-bridge AC-DC voltage source converters (VSC). The bandwidth of PI controller must be relatively wide. This leads to the voltage ripple produced in the control signal, as known that its ripple frequency has twice of the line frequency and cause the 3rd harmonic of an input current. A Ripple Voltage Estimator (RVE) algorithm and Feed-Forward Compensation (FFC) algorithm are proposed and added to the conventional control. The RVE algorithm estimated the ripple signal to subtract it occurring in the voltage loop. As a result, the 3rd harmonic of the input current can be reduced, and hence the Total Harmonic Distortion of input current (THDi) are improved. In addition, the FFC algorithm will offer a better dynamical response of output voltage. The performance evaluation was conducted through the simulation and experiment at 110Vrms/50Hz of the input voltage, with a 600 W load and 250 V<sub>dc</sub> output voltage. The overall system performances are obtained as follows: the power factor at the full load is higher 0.98, the harmonic distortion at AC input power source of the converter is under control in IEC61000-3-2 class A limit, and the overall efficiency is greater than 85%.

This Ph.D. Dissertation focuses on the proposal of a novel converter topology applied to the connection of an energy storage system, composed of a supercapacitor bank and a battery bank, to the dc bus of a residential microgrid. The proposed full-bridge-forward integrated dc-dc converter presents high voltage gain between the input and output, a fundamental requirement for the desired application, bidirectional power flow, galvanic isolation, among other features. The integration process, operation stages (including converter waveforms and equations), design methodology, dc modeling, among others, are presented. Three different clamping circuits structures are studied and applied to the proposed converter. Moreover, a comparison including several parameters with the dual active bridge converter, which is one of the most used topologies for similar applications is performed, highlighting the lesser number of active switches. Experimental results of the proposed converter in different operation modes are presented, validating the theoretical analysis. Experimental results of the dual active bridge converter are also presented and its performance is compared to the proposed converter, where it can be seen that the efficiency of the proposed converter is higher. The topology application is directed to microgrid systems, which attract high attention nowadays due to the possibility of renewable electric energy generation through distributed energy resources and with high reliability.
Esta Tese de Doutorado tem como foco a proposta de uma nova topologia de conversor aplicado para conexão de um sistema de armazenamento de energia, composto de um banco de supercapacitores e um banco de baterias, ao barramento CC de uma microrrede residencial. O conversor CC-CC integrado full-bridge-forward proposto apresenta alto ganho de tensão entre a entrada e saída, requisito fundamental para a aplicação desejada, fluxo de potência bidirecional, isolação galvânica, entre outras características. O processo de integração, etapas de operação (incluindo formas de onda e equações do conversor), metodologia de projeto, modelagem CC, entre outros, são apresentados. Três diferentes estruturas de circuitos grampeadores são estudadas e aplicadas ao conversor proposto. Além disso, uma comparação de diversos parâmetros com o conversor dual active bridge, que é uma das topologias mais utilizadas para aplicações semelhantes é realizada, destacando o menor número de interruptores. Resultados experimentais do conversor proposto em diferentes modos de operação são apresentados, validando as análises teóricas. Resultados experimentais do conversor dual active bridge também são apresentados e o seu desempenho é comparado ao do conversor proposto, onde se observa que o rendimento do conversor proposto é superior. A aplicação da topologia é voltada para sistemas de microrrede, os quais atraem grande atenção atualmente devido à possibilidade de geração de energia elétrica de maneira renovável através de fontes distribuídas e com elevada confiabilidade.
