Abstract

"FORNECIMENTO DE ENERGIA DE MODO DE COMUTAçãO COM PROTEçãO CONTRA CORRENTE EXCESSIVA". Trata-se de um fornecimento de energia de modo de comutador sintonizado, uma voltagem zero é mantida através de um comutador de transistor (Q3), durante intervalos de comutação tanto de desligamento quanto de ligação do comutador de transistor. O fornecimento de energia de modo de comutador sintonizado funciona em um controle de modo de corrente, em uma base de controle de impulso de corrente por impulso corrente. Um circuito de proteção contra corrente excessiva (200) incapacita o comutador de transistor quando uma condição de corrente excessiva persistir por mais tempo do que um primeiro intervalo que é substancialmente mais longo do que o período de um dado impulso de corrente no comutador de transistor. O funcionamento do comutador de transistor não sofre perturbação, quando a condição de corrente excessiva dura somente um intervalo mais curto do que o primeiro intervalo.
