Abstract :
A new quasi-resonant PWM converter is proposed. The proposed converter is constructed by using a resonant network in parallel with the switch of the conventional PWM converter. A new PWM converter achieves zero-voltage switching for all switching devices without increasing their voltage and current stresses
