Abstract

This paper presents a feasibility study of a zero voltage switching (ZVS) PWM full bridge (FB) DC-DC converter with high-frequency planar transformer-link. The soft-switching PWM FB DC-DC converter newly-developed for a switching power amplifier in a plasma generator can achieve soft commutations in switching power devices under the wide range of load power. Moreover, it can attain the effective reduction of idling power due to the phase-shift PWM scheme. In this paper, the essential experimental data obtained from a 100kHz-8kW prototype is described to demonstrate the practical effectiveness of the ZVS-PWM FB DC-DC converter.
