Conversor Cc-cc Elevador/Abaixador Zvzcs Pwm com Grampeamento Ativo

Abstract

Este artigo apresenta o conversor CC-CCbidirecional em corrente (Elevador/abaixador) com comutação suave ZVZCS (zero voltage zero current switching) e grampeamento ativo, utilizando um único interruptor auxiliar. As perdas em comutação são reduzidas através da implementação de um circuito snubber ativo, o qual provê comutação sob tensão nula (ZVS) na entrada em condução de todos os interruptores e também no bloqueio do interruptor auxiliar. O bloqueio do interruptor principal ocorre com comutação sob corrente nula (ZCS). Dentre as suas principais características estão robustez, baixo peso e volume e alta eficiência. O principio de operação em regime permanente, análise matemática, simulação numérica e resultados experimentais de um protótipo de laboratório são apresentados.
