摘要
介绍了一种采用无源功率因数校正方法降低电源谐波含量的方案。实验结果表明,采用无源功率因数校正的方法成本低,性能好,容易达到各项EMC标准,适合于中小功率电源。
A proposal using passive power factor correction method to reduce harmonics emission is introduced in this paper.It indicats that the method is suitable for middle and small power supply with lower cost,better performance and easy to meet EMC standard requirements.
