A dual‐passive snubber (DPS) for dual‐switch forward converter is presented. Snubber networks provide zero‐current turn‐on and zero‐voltage turn‐off conditions for dual switches. DPS achieves soft switching conditions for power diodes at secondary side of transformer. The detailed circuit operation of converter with proposed passive snubber, theoretical analysis and design example are presented. The measured result taken from a laboratory prototype rated at 160 W (32 V/5 A), input voltage of 150 V‐DC and switching frequency of 300 kHz. The peak efficiency is 93%.
