摘　　要：为了抑制开关类电磁干扰,缝制设备控制系统中常用到EMI电源滤波器。论文以缝制设备IPM模块的低频开关噪声为研究对象,通过对滤波器理想共模、差模等效模型的插入损耗进行分析,设计出匹配的EMI电源滤波器。并对设计出的EMI电源滤波器进行了仿真,仿真结果表明该方案可以实现对开关噪声的抑制。EMI Power Filter is usually used in the control system of sewing equipment in order to restrain electromagnetic interference from switch noise. This article designs the appropriate EMI power filter by researching the low frequency switch noise of sewing equipment＇s IPM modular and analyzing filter＇s Insertion Loss of its ideal common and differential mode. Simulation is done which proves that the EMI Power Filter can restrain the switch noise.
