An interleaved totem-pole boost bridgeless rectifier with reduced reverse-recovery problems for power factor correction is proposed in this paper. The proposed converter consists of two interleaved and intercoupled totem-pole boost bridgeless converter cells. The two cells operate in phase-shift mode. Thus, the input current can be continuous with low ripple. For the individual cells, they operate...
A generic model of a double bridge "AC inductor" based Gyrator-behaved APFC is presented, analyzed and verified by simulation and experiments. Based on the results of the study, a design procedure is developed for specifying the control law and the optimal parameters for ZVS and minimum conduction losses of the proposed APFC. The proposed APFC requires neither line voltage, nor input current...
