摘　　要：Power factor correction (PFC) is widely used in many industry fields. In this paper, a novel multiplexed and paralleled PFC rectifier (MPPR) is proposed. Compared with the paralleled traditional six-switch buck-type PFC rectifier (SSBPR), the proposed one uses fewer switches by multiplexing. And it is beneficial for system hardware design. The commutation states of the rectifier are illustrated in detail. By comparing the active power switches, it is shown that the efficiency of the rectifier is similar to that of the traditional paralleled one. Because the commutation states for the upper and lower parts of the rectifier are different, the controller of the converter is analyzed step by step. The forward duties and the inductor current references are discussed by considering the different input voltages of the upper and lower parts of the MPPR. Then the controller is presented and analyzed. Finally the effectiveness of the MPPR is verified by experiments.
