Abstract :
In this paper a new single-phase rectifier is introduced, which features high power factor, regulation by conventional PWM technique, ZVS commutation and clamping action in both switches, and instantaneous average line current control. This rectifier consists of a front-end full-bridge diode rectifier followed by a ZVS-PWM, buck-boost active-clamping, boost converter. Experimental results are presented, taken from a laboratory prototype rated at 1.6 kW, input AC voltage of 220 V rms, output DC voltage of 400 V, and operating at 100 kHz. The measured efficiency at full load was 95%
