A new family of soft switching PWM non-isolated DC-DC converters with Active auxiliary Edge-Resonant Cell

This paper is concerned with a family of soft switching Pulse Width Modulation(PWM) DC-DC converter employing a novel Zero Voltage and Zero Current Switching(ZVZCS) Active auxiliary Edge-Resonant Cell(AERC). The non-isolated DC-DC converters introduced here can achieve a high frequency ZVS and ZCS operations in a main and an auxiliary switch with minimizing the voltage and current stresses as well as circulating currents. For demonstrating the effectiveness of the new soft switching cell, the boost DC-DC converter is evaluated by simulations and experiments using its 100 kHz laboratory prototype. In addition to that, the one-switch dual boost DC- DC converter is newly demonstrated as the new AERC-applied high voltage step-up power converter.
