Abstract :
A novel zero voltage switching (ZVS) isolated converter is presented. The output voltage doubler is used on the output side to achieve the boost type of voltage conversion ratio. Active-clamping technique is adopted to realise the ZVS turn-on of all switches. The proposed circuit has no large output inductor such that the adopted circuit has a simpler structure, lower cost and no effective duty loss. Finally experimental results based on a 300 W prototype are provided to verify the effectiveness of the proposed converter.
