In this paper, open loop and closed loop response of high efficiency, high power density, active-clamp forward converter with zero voltage switching multi resonant converter is presented. The structure of the proposed converter is the same as that of the conventional active-clamp forward converter. This paper presents a model for closed loop controlled modified forward converter. The objective of this converter is to minimize the size of transformer and filter. The proposed converter can achieve high efficiency and low electromagnetic-interference noise resulting from the soft switching. The operational principle and design example are presented. The simulation results are compared with the analytical results.
