Conversor CC-CC de Alto Ganho com Compartilhamento da Corrente de Entrada, Modulação Phase-Shift e Compactação do Filtro de Saída

Abstract

Neste trabalho apresenta-se um conversor cccc apto a operar com fontes de baixa tensão e elevada corrente de entrada. A topologia proposta é baseada em uma configuração de conversores Forward com entradas conectadas em paralelo e saídas conectadas em série. A referida configuração permite o compartilhamento da corrente de entrada entre os módulos associados e resulta em elevado ganho estático. Mediante a aplicação de modulação phase-shift ao acionamento dos interruptores, há a possibilidade de redução do volume dos componentes que compõem o único filtro de saída da estrutura. O estudo realizado neste trabalho inclui: análise das interligações entre conversores Forward e das etapas de operação, formas de onda teóricas, a modelagem do conversor orientada ao controle e proposta de uma estratégia de controle. A partir de um protótipo de 1 kW são extraídos resultados experimentais que validam a teoria e as equações derivadas ao longo do texto.
