A soft switching interleaved forward converter with current doubler rectifier is presented in this paper. Active clamp circuit is used in the primary winding of transformer to recycle the energy stored in the leakage inductor and magnetizing inductor so that the voltage stresses of switches are reduced. The leakage inductance of transformers, the magnetizing inductance and the clamp capacitance is...
A new soft switching dc/dc converter is presented to achieve zero voltage switching (ZVS) of all switching devices. In the proposed converter, an auxiliary switch and clamp capacitor is used to recycle the energy stored in the leakage inductor, limit the voltage stress of switches and achieve resonance between the transition interval between the main and auxiliary switches. During the transition interval,...
This brief presents the analysis, design, and implementation of zero-voltage switching (ZVS) active clamp converter with series-connected transformer. A family of isolated ZVS active clamp converters is introduced. The technique of the adopted ZVS commutation will not increase additional voltage stress of switching devices. In the adopted converter with series-connected transformer, each transformer...
