Abstract

a presente divulgação refere-se a circuitos e métodos para controlar um regulador de comutação de reforço baseado em corrente de indutor. uma tensão de entrada é acoplada a um primeiro terminal de um indutor e o segundo terminal do indutor é alternadamente acoplado entre uma tensão de referência e uma tensão de saída reforçada. a tensão de entrada está adicionalmente acoplada a um primeiro terminal de um circuito de integrador, e um segundo terminal de circuito de integrador pode ser alternadamente acoplado entre a tensão de referência e a tensão de saída reforçada, por exemplo, para produzir uma tensão correspondente a uma corrente no indutor. o presente circuito pode ser utilizado para controle de tensão ou modos de controle de corrente, ou ambos, em um regulador de comutação de reforço.
