Abstract :
In this paper, a new two-switch zero current switching (ZCS) bridgeless boost rectifier with high power factor (PF) is proposed. The proposed bridgeless converter is based on a totem-pole configuration which allows the current to flow from high side to low side and vice versa during resonance. Hence, no auxiliary switch is needed to provide soft switching for all semiconductor devices. An average current mode controlled is employed to provide high PF and smooth input current waveform. A detailed analysis of the converter operations and controls are presented.
