English abstract This paper presents a novel family of Zero Voltage Transition (ZVT) DC-DC PWM Converters that uses a resonant circuit as auxiliary commutation source to control the current through the auxiliary switch without additional current stresses on main devices. The improved ZVT commutation cell enables the main switch to be turned on and off at Zero Voltage Switching (ZVS) and the auxiliary switch to be turned on and off at Zero Current Switching (ZCS) from zero to full-load
Portuguese abstract Este trabalho apresenta uma nova família de conversores CC-CC PWM ZVT os quais utilizam um circuito ressonante como fonte auxiliar para controlar a corrente através da chave auxiliar sem agregar esforços adicionais de corrente nos dispositivos principais. A célula de comutação aperfeiçoada possibilita a comutação da chave principal sob tensão nula e a comutação da chave auxiliar sob corrente nula desde carga nula até carga nominal
