Abstract :
A technique using inductor feedback is presented for achieving zero-voltage switching (ZVS) in PWM controlled topologies. These converters exhibit low voltage and current stresses characteristic of hard-switched PWM converters, yet achieve ZVS with minimal current and voltage rating of the auxiliary soft-switching circuitry. Based on this technique, an experimental 730 W, 300 kHz boost converter is designed for universal off-line power factor correction. A complete analysis and a design procedure are also presented
