摘要: An improved zero-voltage zero-current switching (ZVZCS) full bridge PWM converter is proposed in this paper. The consists of two inverters the primary side and rectifiers secondary total power equally distributed to each rectifiers. Also a current transformer winding naturally reset by input source. Therefore, for leading leg switches lagging are achieved without requiring any additional components increases reliability system. Furthermore, multi-level voltages shown at output filter reduce size. operational principle analysis presented verified 700W prototype.
