Abstract
A novel zero current soft switching (ZCS) pulse width modulation (PWM) half-bridge DC-DC converter is presented. ZCS commutation can be achieved for a wide load power setting with the asymmetrical PWM-based duty-cycle control scheme under a constant switching frequency. The effectiveness of the proposed converter topology and soft switching scheme are demonstrated with experimental results using the 0.8 kW - 55 kHz prototype.
