摘　　要：本文介绍了PFC模块的主要原理及应用,对FOT(fixed off time)模式进行了讨论,设计一台400V/375W的电源,并通过SABER软件进行了仿真验证。仿真及实验结果表明,该电源系统的的功率因数能够达到0.99以上,实现了功率因数校正的目的,可以作为高效率LED驱动电源的PFC部分应用到实际电路中。This paper introduces the main principles and application of the PFC module, the FOT（fixed off time）mode is discussed, and a 400V/375W power supply is built, and it is also simulated by the saber software. The simulation and experimental results verify that the prototype can make the power factor reach over 0.99, it also means that we have achieved the purpose of power factor correction, and it can be used as the PFC part of the high efficiency LED driving power supply in the actual circuit.
