摘要：
In this paper, a novel 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 implemented in the proposed soft-switching converter topology to achieve wide load variation range soft-switching PWM constant frequency operation of the DC-DC converter, to minimize circulating current. The presented converter operates with ZVS for leading bridge leg active power switches due to lossless snubber capacitors, and ZCS for lagging bridge leg active power switches with the aid of the high frequency transformer parasitic leakage inductance component and tapped inductor filter. The effectiveness of the proposed soft-switching DC-DC converter is verified in experiment with 2kW 100kHz breadboard setup using IGBTs. Actual efficiency of 94% is obtained for the wide load variation range.
