Abstract

This paper presents an analysis of the effects of the saturable resonant inductor on the rectifying diode reverse recovery of zero-voltage-switching quasi-resonant and full-bridge zero-voltage-switched PWM power converters. The clamping circuit´s design, considering a saturable resonant inductor, is presented and compared with the design of a clamping circuit with a linear resonant inductor. A diode model with reverse recovery is employed to simulate the effects
