一种能有效抗电网干扰的噪声滤波器

A Kind of Noise Filter for Restraining EMI of Electric Network

介绍了一种有效的噪声滤波器。以分析噪声的传播方式、结合滤波器所需对应的开关电源工作频率为基础来设计滤波器,无需复杂的计算,对不同工作频率的开关电源有较强的针对性。

A simple and useful procedure for noise filters is presented.This procedure is based on the analysis of noise and the frequency of SMPS.This procedure needs no complex computing and fits SMPS with certain frequency well.
