Abstract

A new zero-voltage switching (ZVS) pulse width modulation (PWM) DC-DC converter using MOSFETs is proposed in this paper. The proposed converter achieves ZVS with reduction in voltage and current stresses across switches to improve the efficiency by minimizing the switching and conduction losses. The predicted operation principles and theoretical analysis of the presented converter are verified with a prototype of a 360 W, 50 V/6 V and 100 kHz PWM half bridge buck converter. Additionally, at full output power in the proposed soft switching converter the overall efficiency, which is 80% in the hard switching case, increases to about 95%.
