Abstract

Soft switching full-bridge phase-shifted PWM converter using IGBTs with auxiliary transformer is presented in this paper. Zero-voltage and zero-current switching for all power switches is achieved for full load range from no-load to short circuit by adding active energy recovery snubber and auxiliary circuits. The principle of operation is explained and analysed and experimental results are presented. The properties of the converter are verified on a laboratory model
