A family of high performance power-factor-correction circuit for actively clamped resonant DC link inverter

This paper presents a new family of high performance power-factor-correction circuit for actively clamped resonant DC link inverter. Only by adding a snubber inductor and a clamp diode, the circuit effectively alleviates the reverse recovery of rectifier diode with simple control and low voltage stress. The operation principle of this converter is given in detail, and system control and design considerations are discussed. A prototype was developed rated at 1.6 kW, input AC voltage of 220 V/sub rms/, output DC voltage of 400 V, and operating at 100 kHz. The measured efficiency at full load is 96%.
