                            <p>A new soft switching passive snubber cell for pulsewidth modulation (PWM) DC–DC converters is proposed in this paper. In the newconverter, the switch is turned on with zero current switching (ZCS) and isturned off with zero voltage switching (ZVS). Besides, the main diode is turnedon and off with ZVS and ZCS, respectively. Thus, the switching losses both ofswitch and main diode are reduced. In addition, the reverse recovery losses ofmain diode are significantly minimized. The auxiliary semiconductors in thesnubber cell are completely operated with soft switching. The proposedconverter has a simple structure, low cost and ease of application. In thisstudy, the detailed theoretical analysis of new converter is made and a 200 Wlaboratory prototype is implemented. Finally, the theoretical analyses areverified with the experimental results.</p></trans-abstract>
