摘要
介绍了ＶＦＳｅｐｉｃＰＦＣ电路的工作原理，提出了其主电路和控制电路的设计方法，样机设计和实验证明该方法的正确性。与通用的ＢｏｏｓｔＰＦＣ电路相比，ＶＦＳｅｐｉｃＰＦＣ电路无需专用ＩＣ，控制电路设计和调试简单；输出电压可以高于也可以低于输入电压峰值；易于实现输入输出隔离。
This paper introduced the working principle of VF Sepic PFC circuits first, and then proposed the design methods of its main circuit and control circuit. It is proved by a prototype design and experimental results that the methods are effective. Compared with generally used Boost PFC circuits, VF Sepic PFC circuits have the following advantages: (1) Because there is no need of special purpose IC, the design and debugging of the control circuits are quite simple; (2) The voltage output can be higher or lower than the voltage peak input; (3) Input output isolation can be easily implemented.
