Abstract :
Buck and flyback zero switching power factor correction circuits are proposed. These converters are characterised by zero current switching and low output voltage. Another feature is their constant frequency operations. Control and design issues of the circuits are discussed. Simulation and experimental results shows that their power factor is high and suitable for high frequency power factor correction circuit
