Abstract

Este trabalho realiza uma comparação de três conversores CC-CC não isolados de elevado ganho estático. Esses conversores são derivados de configurações em multiestágio, multi-fase, elementos magnéticos e células multiplicadoras de tensão. O artigo revisa os métodos empregados para gerar conversores com alta taxa de conversão e caracteriza-os individualmente e, em seguida, integra as técnicas para gerar os três conversores. A análise dos conversores inclui o número de componentes, esforços de tensão e corrente, perdas nos componentes, rendimento, ganho estático e ondulação da corrente de entrada. Os conversores foram testados com uma potência de 1 kW, uma tensão de saída de 800 volts e um ganho estático superior a 13 vezes. Os resultados experimentais confirmam o estudo teórico, na qual o conversor I obteve rendimento de 87%, enquanto os conversores II e III alcançaram rendimentos em torno de 95%.
