Abstract :
A high efficiency power factor correction converter is proposed in this paper. By using an auxiliary switch, a small auxiliary inductor and a clamp capacitor, ZVS for all switches is achieved. To eliminate the voltage ringing across the output rectifier diode, a small diode DC is added to clamp the voltage. A 500 W/103 kHz PFC prototype is built up for the universal line application to verify the theoretical analysis. The efficiency can reach 94.1% at 90 V input with full load
