Abstract
In this paper a novel prototype of the high frequency transformer linked full-bridge type soft-switching phase-shift PWM control scheme DC-DC power converter is presented. A tapped inductor filter is newly implemented in the proposed converter topology to achieve such advantageous characteristics as wide load variation soft-switching PWM constant frequency operation, low circulating and idling currents. The effectiveness of the proposed soft-switching DC-DC power converter is verified in experiment by using 2kW 100kHz breadboard setup using IGBTs. Efficiency of 94% was obtained over the wide load range.
