| Abstract |
In this paper, a novel high frequency transformer linked full-bridge type soft-switching phase-shift
PWM DC-DC power converter for the telecommunication and automobile energy plants is presented. A
tapped inductor filter is put into practice to achieve wide load variation range soft-switching PWM
constant frequency operation of the DC-DC converter, to minimize circulating current in the high
frequency inverter stage. The presented converter operates with ZVS for leading bridge leg active power
switches and ZCS for lagging bridge leg active power switches. The effectiveness of the proposed softswitching
DC-DC converter is verified in the experiment on 2kW 100kHz breadboard circuit using
IGBTs. The actual efficiency of 94% is obtained for the wide load variation range. |
