Analysis and design for RCD clamped snubber used in output rectifier of phase-shift full-bridge ZVS converters

摘要

Detailed analysis and parameter design for a resistor-capacitor-diode (RCD) clamped snubber used in the output rectifier of phase-shift full-bridge zero-voltage-switching (PS-FB-ZVS) power converters are presented. Design equations and some properties of the clamped circuit are also highlighted.
