摘要

功率因数校正（PFC）广泛应用于许多工业领域。提出了一种新型的多路并联PFC整流器（MPPR）。与并联的传统六开关buck型PFC整流器（SSBPR）相比，该整流器采用多路复用的方式使用更少的开关。对系统的硬件设计也有一定的帮助。详细说明了整流器的换相状态。通过对有功功率开关的比较，表明该整流器的效率与传统并联整流器的效率相当。由于整流器上下两部分的换相状态不同，对变换器的控制器进行了逐步分析。通过考虑MPPR上下两部分不同的输入电压，讨论了正向负载和电感电流参考。然后对控制器进行了介绍和分析。最后通过实验验证了该方法的有效性。

Multiplexed and Paralleled PFC Rectifier and Its Control

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.
