Estudo e Validação Experimental de um Conversor Multinível Modular Entrelaçado CA-CC Monofásico Para Aplicações de Transformadores de Estado Sólido

Abstract

Este artigo tem como objetivo apresentar o estudo teórico e a obtenção de resultados experimentais de uma topologia monofásica baseada em um conversor multinível modular entrelaçado. A estrutura pode ser empregada como o estágio ca-cc em aplicações de transformador de estado sólido. O objetivo é a conexão entre uma rede elétrica ca de média tensão e uma rede cc de baixa tensão. A nova técnica de entrelaçamento divide as correntes através das pernas do conversor multinível modular e é responsável pela modulação de tensão nos submódulos. O transformador de média frequência de 10 kHz fornece isolação galvânica e conecta o conversor multinível modular entrelaçado a um conversor de ponte completa. As características do conversor são discutidas, considerando a estrutura, o princípio de operação, a técnica de modulação e o esquema de controle. O sistema de controle regula a corrente de entrada e a tensão de barramento, no lado de alta tensão, e a tensão de saída e o fluxo de potência bidirecional, no lado de baixa tensão. A validação experimental do conversor é feita com um protótipo de pequena escala.
