Abstract	This paper presents a novel quasi-single-stage topology for a 3-phase input AC/DC power converter with power factor correction (PFC). There are soft-switching conditions of all switches, low voltage stresses on the output diodes, and smaller input and output filters in this topology. A quasi-wave prototype with 380 VAC+/-30% input, 40-60 VDC output was built and its efficiency was about 93%. The input harmonic current meets IEC61000-3-2 Class A standards, and the total harmonic distortion level is about 10% at rated input voltage. Experimental results show that the novel AC/DC converter with PFC has the advantage of low cost, small size, light weight and high efficiency
