Análise, Projeto e Desenvolvimento de um Conversor Duplo Forward Zcs com Ressonânica Dupla para Aplicação em Fontes Chaveadas Isoladas

Abstract

Este trabalho apresenta um novo conversor Duplo Forward que consiste de dois conversores Forward acoplados ao mesmo núcleo magnético permitindo o uso completo do ciclo de histerese do transformador. No intuito de reduzir as perdas por chaveamento e interferências eletromagnéticas, uma célula de comutação suave, a qual permite a comutação dos interruptores sob corrente nula (ZCS), é utilizada. Essa estrutura propicia comutação não dissipativa para uma ampla faixa de carga e uma melhor distribuição de corrente entre os interruptores utilizados. O estudo teórico completo acerca do conversor Duplo Forward proposto é apresentado e corroborado por resultados experimentais obtidos com a construção de um protótipo de 450 W.
