This thesis proposes two DC-DC converters. One is novel isolated bidirectional DC-DC converter (IBDC), and the other is novel isolated unidirectional high step-up DC-DC converter (IUHSDC). The IBDC incorporates a three-winding coupled inductor and a voltage multiplier to feature galvanic isolation and achieve high conversion ratio, which is able to recycle leakage energy without the use of active or passive snubber circuits. Even though the proposed IBDC only includes four active switches, it can process power bi-directionally. This switch number is the minimum as compared with other isolated bidirectional DC-DC converters. With respect to converter efficiency, all switches can be operated with soft switching, reducing switching loss significantly. The IUHSDC utilizes two coupled inductors and two voltage multipliers to function galvanic isolation and high conversion ratio. The proposed IUHSDC has the advantages of low turns ratio, low voltage stresses on active components, soft switching, and leakage energy recycling. The operation principle, steady-state analysis, design considerations, and experimental results of both converters are presented in detail. Prototypes of the two converters are built, tested and measured, which validate the proposed IBDC and IUHSDC.

Повний текст джерелаDue to the growing concern about the impact on the environment of the use of Nowadays, there is great concern about the environmental impact caused by the use of fossil fuels as a vehicle energy source. (VE) due to the use of fossil resources, their energy efficiency and low noise, compared to the convention.There are four major barriers to EV development: the high cost and low life cycle of batteries, the complexity of the charger, the lack of charging stations and the harmonic distortion introduced into the network due to some types of battery chargers For most EVs, charging can be done at home (slower) or at charging stations (faster).Os carregadores de baterias podem ser classificados como (no veículo) e (exterior ao veículo), com um fluxo de potência unidirecional ou bidirecional. O carregamento unidirecional é o mais simples, pois, visto que o fluxo de potência é apenas numa direção, limita os requisitos de hardware, simplifica os problemas de interligação e tende a reduzir a degradação das baterias.The main objective of this work is the development and implementation of a controller for a resonant DC-DC converter, which will be used in an EV to charge the battery bank.This work starts by presenting an analysis to the existing literature, relevant to the study of resonant converters.\parThen, a mathematical study of the system is made, in order to obtain a linear model.After obtaining this linear model, the controllers design is developed for the system and further analyzes are presented.Next, simulations are done in order to corroborate the theoretical model and the designed controllers.Finally, the various simulation results are analyzed, drawn conclusions about them and presented suggestions for future work.
Nos dias de hoje, existe uma grande preocupação relativamente ao impacto ambiental causado pela utilização dos recursos fósseis como fonte de energia dos veículos. Consequentemente, tem havido um crescente interesse nos veículos elétricos (VE) devido à não utilização de recursos fósseis, à sua eficiência energética e ao baixo ruído sonoro, em relação aos veículos convencionais. Existem quatro importantes barreiras no desenvolvimento de VE: o elevado custo e o baixo ciclo de vida das baterias, a complexidade do carregador, a falta de postos de carregamento e a distorção harmónica introduzida na rede devido a alguns tipos de carregadores de baterias. Para a maior parte dos VE, o carregamento pode ser feito em casa (mais lento) ou em postos próprios de carregamento (mais rápido).O objetivo principal deste trabalho consiste no desenvolvimento e na implementação de um controlador para um conversor DC-DC ressonante que será utilizado num VE para o carregamento do banco de baterias.Inicialmente, será feito um ponto de situação em relação à literatura existente relativa ao estudo dos conversores. De seguida, é feito um estudo do ponto de vista matemático do sistema, de modo a obter um modelo linear. Após a obtenção desse modelo linear, são desenvolvidos os controladores para o sistema e apresentadas as devidas análises.De seguida, são feitas simulações de modo a corroborar o modelo teórico e os controladores projetados. Por fim, são analisados os vários resultados de simulação, tirando conclusões sobre os mesmos e apresentadas sugestões para trabalhos futuros.

Повний текст джерелаNos últimos anos, tem havido um aumento de veículos elétricos devido a uma questão ambiental e a um interesse nesta nova tecnologia. Esta dissertação propõe uma arquitetura de conversão de energia com a implementação de um posto de carregamento rápido para baterias, como as dos veículos elétricos. Esta arquitetura é baseada nos Transformadores de Eletrónica de Potência (TEP). Inicialmente, irá ser realizado o estado de arte, e, através da literatura analisada relativamente aos TEP’s, serão escolhidas as soluções mais adequadas para esta arquitetura. Após escolhida a ideia para o caso de estudo, e, posteriormente, a verificação do estudo elétrico e matemático, este sistema será simulado de modo a consolidar o sistema teórico. Nestas simulações, irá se avaliar os diferentes modos de carregamento das baterias, carregamento em modo tensão constante, carregamento em modo corrente constante e carregamento em modo corrente constante e tensão constante. Também se irá escolher o melhor método e mais eficaz de carregamento das baterias. Verificar-se-á a fiabilidade deste sistema, fazendo-se simulações com desequilíbrios no modelo, como por exemplo, carregar o sistema com as baterias em desiquilíbrio, ou seja, cada bateria tem um estado de carga diferente das outras, e causar uma falha num IGBT de uma das pontes do conversor DC-DC unidirecional isolado ou do retificador multinível, a duas configurações são utilizadas em alguns modelos do transformador eletrónico de potência. Por fim, irão ser tiradas conclusões e serão dadas recomendações de trablhos futuros para melhoramento desta dissertação.
In recent years, there has been an increase in electric vehicles due to an environmentalissue and an interest in this new technology.This dissertation proposes an architecture of energy conversion with the implementation of a fast charging station for batteries, such as those of electric vehicles.This architecture is based on the Power Electronic Transformers (PET). Initially, the state of art will be realized, and, through the analyzed literature regarding the PET's, will be chosen the most appropriate solutions for this architecture.After choosing the idea for the case study, and later the verification of the electrical and mathematical study, this system will be simulated to consolidate the theoretical system.In these simulations, we will evaluate the different modes of charging the batteries, charging in constant voltage mode, charging in constant current mode and charging in constant current mode and constant voltage. You will also choose the best and most effective method of charging the batteries. The reliability of this system will be verified by simulations with imbalances in the model, such as loading the system with unbalanced batteries, ie each battery has a different state of charge than others, and cause an IGBT to fail from one of the isolated single-way DC-DC converter or multi-level rectifier, two configurations are used on some models of the power transformer. Finally, conclusions will be drawn and future work recommendations will be given to improve this dissertation.
