Modulação, Modelagem e Controle do Inversor Boost a Capacitor Chaveado

Abstract

O presente artigo analisa um inversor elevador bidirecional de estágio único concebido a partir da integração entre o inversor diferencial boost e células a capacitor chaveado. O inversor boost convencional, mesmo sendo elevador, possui limitação de ganho devido às perdas e, por isso, não é capaz de atender a todas as especificações de elevação. A inserção de células multiplicadoras a capacitor chaveado permite ampliar seu ganho estático sem aumentar os esforços de tensão sobre seus componentes. No entanto, a topologia resultante é não linear e apresenta elevada quantidade de componentes armazenadores de energia, o que dificulta sua modelagem. Neste artigo, realiza-se a análise estática e dinâmica do inversor boost diferencial a capacitor chaveado sob diferentes tipos de modulação. Propõe-se um circuito equivalente e um modelo de pequenos sinais de ordem reduzida e dinâmica equivalente, além de uma técnica linearização de ganho estático que reduz consideravelmente a distorção harmônica da tensão de saída, regulada em malha fechada por meio de um controlador ressonante. O artigo ainda apresenta uma comparação entre o inversor diferencial boost e sua versão com célula multiplicadora a capacitor chaveado e valida o estudo por meio de um protótipo com potência de 250 W, tensão de entrada de 60 V, frequência de comutação de 50 kHz e tensão de saída de 220 V.
