Abstract

"PROCESSO E DISPOSITIVO PARA CONVERSãO DE ENERGIA UTILIZANDO TOPOLOGIA DE REFORçO COM CIRCUITO DE AMORTECIMENTO ISENTO DE PERDA". Uma topologia de conversão de reforço é freq³entemente utilizada como circuito de correção de fator de potência auxiliar em um retificador. Um problema significativo com esta topologia reside no diodo retificador. Este diodo deve ser de um tipo de alta voltagem em uma aplicação de reforço e apresentará portanto uma grande corrente de recuperação inversa antes de bloquear a voltagem. Esta corrente pode causar perdas significativas. Com a solução de acordo com a invenção a corrente de recuperação será tratada de forma mais eficiente que qualquer outra forma obtida em soluções anteriores. O circuito proposto compreende essencialmente um circuito de reforço, no qual um principal e primeiro indutor L1(3) e um principal e primeiro diodo D1(4) são ligados em série desde uma entrada até uma saída e um principal e primeiro capacitor C1(5) de uma saída para terra. Um principal e primeiro transistor M1(1) é ligado desde um ponto entre o primeiro indutor L1(3) e o primeiro diodo D1(4) para terra. Um auxiliar e segundo indutor L11(6), um segundo diodo D11(7) e um segundo transistor M11(2) são ligados em série desde um ponto entre o primeiro indutor L1(3) e o primeiro diodo D1(4) para terra. Dois outros diodos, um terceiro e um quarto diodo D12(1), D13(9) são ligados em série desde um ponto entre o segundo diodo D11(7) e o segundo transistor M11(2) para a saída.
