Retificador Boost Bridgeless Unidirecional Monofásico Com Célula De Capacitor Chaveado

Abstract

Este trabalho apresenta a topologia de retificador boost bridgeless híbrido unidirecional monofásico com célula de capacitor chaveado tipo ladder na saída. A estrutura multiplica a tensão de saída e divide os valores de tensão sobre os semicondutores por meio de células de capacitor chaveado. As características da topologia boost convencional integrada à célula de capacitor chaveado proporcionam boa regulação de tensão de saída e de corrente de entrada, desta forma proporciona alto ganho associado com alto fator de potência. Também é apresentada uma estratégia para a modelagem dinâmica de conversores híbridos com capacitor chaveado baseada em um circuito equivalente de ordem reduzida. Um protótipo de 1 kW com tensões de 800 V de saída e 220 V de entrada foi desenvolvido para a validação experimental da estrutura. O conversor apresentou um valor máximo de tensão de 400 V nos semicondutores, pico de rendimento de 97,1 % e fator de potência unitário.
