A soft switching pulse-width modulation (PWM) Cuk converter with boost type of active clamp is proposed. Active clamp circuit can help the switching devices in the Cuk converter to be operated at zero voltage switching (ZVS) turn-on. Therefore this converter is suitable for high frequency operation to reduce the size of reactive components. The clamp capacitor and auxiliary switch are connected in...
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,...
A soft switching converter with parallel-connected full-wave rectifiers is presented. In the proposed converter, the primary windings of two transformers are connected in series. Two full-wave rectifiers with ripple current cancellation are connected in parallel at the output side to reduce the current stress of the secondary winding of transformer. The clamp circuit based on an auxiliary switch and...
