Abstract

Patente de Invenção: <B>''CIRCUITO TOPOLóGICO DE COMUTAçãO MODERADA''<D>. A invenção refere-se a um circuito topológico de comutação moderada. Um desligamento e tensão zero é realizado, quando a chave principal é ligada, através da utilização da ressonância do indutor ressonante e do capacitor ressonante, após a chave auxiliar ser ligada. Além disso, durante o desligamento da chave principal, o indutor ressonante resiste a uma queda de tensão, o que faz com que o dispositivo de alimentação de energia, correspondente à chave auxiliar, não alimente energia, quando a chave auxiliar é ligada, assim, realizando a ligação de corrente zero da chave auxiliar e aumentando a eficiência de funcionamento do circuito.
