Abstract

A ZVS input series output parallel (ISOP) forward converter is proposed in this paper. A novel input-in-series topology with an auxiliary diode helps the transformer to demagnetize naturally and the switches to operate with ZVS. And the voltage stresses on the primary switches are clamped at V_in. The operation principle of proposed converter is analyzed in detail with ZVS conditions given. A 1000 W prototype is built and the experimental results are presented to verify the analysis.
