摘　　要：文章着重介绍了使用滤波器改善电子设备电磁兼容性的方法。对设备分类,早期规划,分区安装是成本最低的工程方法,完全可以避免后期昂贵的整改成本。简单描述了各类干扰的传导和耦合路径,电缆长度及其承载电信号频率对耦合的影响,使用滤波器抑制和阻断耦合的方法。滤波器的选用和安装注意事项等工程实际问题。是屏蔽之外改善电磁兼容性的方法,是屏蔽不可或缺的补充手段。This paper mainly introduces the method of using filter to improve the electromagnetic compatibility of electronic equipment.For equipment classification,early planning,partition installation is the lowest cost of engineering methods,which can completely avoid the late expensive cost of rectification.The transmission and coupling path of various kinds of interference,the influence of cable length and the frequency of carrying electric signal on coupling are briefly described.The method of suppressing and blocking coupling by filter is used.The selection and installation of filters and other practical engineering problems.It is a method to improve electromagnetic compatibility outside shielding and is an indispensable supplementary means of shielding.

关 键 词：电磁兼容 滤波器 屏蔽 电磁耦合 电噪声
