Abstract :
Device voltage and current stress analyses are performed for zero-voltage-switched, zero-current-switched, and pulsewidth-modulated (PWM) converters. Results are normalized in terms of converter specifications and dimensionless design constraints to permit stress comparison in various converters without any detailed design. Design guidelines are given for determination of the resonant tank elements and filter inductor that minimize semiconductor stress of quasi-resonant converters.<>
