Abstract:A zero-voltage zero-current-switching (ZVZCS) full-bridge DC-DC converter, based on a dual transformer with two output filter capacitors, is proposed in this paper. The proposed topology is suitable for application in renewable energy at medium voltage, integrated with a DC collection system. To realize voltage and power regulation for the converter, pulse width modulation (PWM) is employed with a fixed duty cycle for the main switches. Through careful design of the turns ratio of the main transformer, most of… Show more
