Abstract

é fornecido um inversor de múltiplos níveis, incluindo uma unidade de entrada de corrente contínua (102), um primeiro comutador bidirecional (104), um segundo comutador bidirecional (106), um terceiro capacitor (c3) e uma unidade inversora (108). a unidade de entrada de corrente contínua inclui um primeiro capacitor (c1) e um segundo capacitor (c2) que são conectados em série entre os terminais positivo e negativo da fonte de potência de entrada de corrente contínua (e). a unidade inversora (108) inclui um primeiro tubo de comutação (q1), um segundo tubo de comutação (q2), um terceiro tubo de comutação (q3), e um quarto tubo de comutação (q4) que são conectados em série codirecionalmente entre os terminais positivo e negativo da fonte de potência de entrada de corrente contínua. um terminal do primeiro comutador bidirecional (104) é conectado a um ponto de conexão entre o terceiro tubo de comutação e o quarto tubo de comutação, um terminal do segundo comutador bidirecional é conectado a um ponto de conexão entre o primeiro tubo de comutação e o segundo tubo de comutação, e o outro terminal do primeiro comutador bidirecional (104) ou o segundo comutador bidirecional é conectado a um ponto de conexão entre o primeiro capacitor e o segundo capacitor. um terminal positivo do terceiro capacitor é conectado ao ponto de conexão entre o primeiro tubo de comutação e o segundo tubo de comutação, e um terminal negativo do terceiro capacitor é conectado ao ponto de conexão entre o terceiro tubo de comutação e o quarto tubo de comutação. um circuito projetado em que uma unidade de entrada de corrente contínua e uma unidade inversora são ligadas em ponte usando dois grupos de comutadores bidirecionais é usado para emitir mais níveis, de modo que uma quantidade aumentada de níveis de tensão de saída reduz o conteúdo harmônico em uma forma de onda de saída. isso melhora a eficiência e a estabilidade do sistema.
