Conversor Wireless Com Retificador ZCS

Abstract

Este trabalho apresenta o estudo e o desenvolvimento de um conversor wireless para carregar supercapacitores, que utiliza redes de imitância para sintonizar o primário e o secundário de um transformador com baixo coeficiente de acoplamento. A frequência de operação do conversor é a frequência de ressonância das redes de imitância e, nesta condição, a rede opera como um conversor V/I (a fonte de tensão na entrada é convertida em fonte de corrente na saída). A rede de imitância do primário alimenta o transformador com corrente de amplitude constante. A rede de imitância no secundário assegura a comutação suave do retificador e corrente constante com baixa ondulação na saída do conversor para toda faixa de operação da tensão na carga. Conversores com esta característica são adequados para alimentar cargas como supercapacitores e baterias.
