In this study, a novel zero‐current transition (ZCT) auxiliary circuit is applied to pulse‐width modulation single‐ended forward converter (PWM SEFC). The proposed ZCT circuit has achieved the power switch zero‐current switching (ZCS) turn‐on; the power switch ZCT turn‐off; the auxiliary switch ZCS and zero‐voltage switching turn on/off and soft‐switching conditions for output diodes. Moreover, the transformer core reset is prepared by the ZCT circuit and tertiary winding is removed. The novel ZCT‐PWM SEFC is analysed at a steady‐state for operating under continuous conduction mode. The proposed ZCT circuit is designed, and the experimental result from a 200 W‐100 KHz prototype is prepared to confirm the theoretical analysis.
