一个单级功率因数校正电路的电磁兼容研究

Study of Electromagnetic Compatibility in Single Stage PFC Circuit

单级功率因数校正电路是一种电路结构简单,成本低,而效果和两级的电路相差无几的电路.但是如果电路设计不合理的话,电路的电磁兼容问题就非常严重.文章通过对电磁兼容传导途径以及单级功率因数校正电路的原理分析,提出了一些解决电路电磁兼容问题的实际措施.实验结果表明:效果不错。

A single stage PFC circuit is introduced in this paper to reduce harmonics.The circuit has many advantages such as simple topology,low cost,and easy to meet harmonic standard.Some EMC problems of the circuit are discussed in this paper,then,several strategies are proposed to reduce them.Experiments are showed in the end to verify the theories.
