| 摘 要： | 本文提出了一种新型交错单级功率因数校正电路(PFC)。为了实现功率因数校正和减小电感体积，boost电感工作在不连续导电模式。此单级PFC电路采用两个boost电路交错运行，减小了输入EMI滤波器的尺寸和开关电流应力，同时也减少了输出纹波。在介绍电路工作原理的基础上，对其输入电流进行了分析，给出了仿真与实验结果。

| Abstract: | This paper presents a novel interleaved single-stage PFC circuit. To achieve high power factor and reduce the PFC inductor size, the boost inductor works in discontinuous-current-mode. To minimize the input EMI filter size and reduce switch current stress, two DCM interleaving parts are implemented within one S2PFC circuit. The proposed interleaving circuit is proved to reduce the output ripple. Based on discussing the working principle of the circuit, the input current is analyzed. The simulation and experiment results are given to validate the design approach. |
