Abstract :
A multi-output quasi-resonant converter suitable for applications up to several hundreds of Watts is presented. It employs a zero-current-switched full-wave push-pull structure, which allows good cross-regulation of the output voltages, high power density and full exploitation of the transformer core. After an analysis of operation, design criteria are given and experimental results of a three-output, 100 W industrial prototype for telecom applications are reported
