摘要
在EMC领域中,电源EMI滤波器设计是非常重要的,它是抑制传导发射和辐射发射非常有效的一种方法,主要从以下几个方面讨论了电源EMI滤波器的设计、特性及选取原则:1）电源EMI滤波器的基本原理、种类及主要特性指标;2）电源线上的干扰类型及电源EMI滤波器的作用;3）电源EMI滤波器设计原则、网络结构、参数选择;4）电源EMI滤波器的安装要求。
It is very important to design power supply EMI filter in EMC domain, and it is one of the effective means available to restrain conductive emission and radiative emission. Several aspects are discussed in this paper : 1) basic principle, category and major characteristics; 2) types of interferences in power supply line and the function of EMI filter ; 3) design rule, network configuration and parameter selection and; 4) installation requirements of power supply EMI filter.
