摘要
电磁干扰通过传导或辐射两种途径作用在电子设备上 ,使它产生非有用信号 (干扰 )响应 ,误动作 ,甚至被彻底破坏。 EMI电源滤波器是一种连接成低通滤波器的 ,由无源元件构成的多端口网络。它不仅能衰减沿电源线传导的 EMI能量 ,同时也对 EMI的辐射有显著的抑制作用。 EMI电源滤波器是电子设备设计人员进行电磁兼容设计时常用的重要手段。
EMI causes undesirable responses,malfunctions or complete failures in electronic equipment.It can be conducted or radiated.An EMI Power Line Filter is a multiple port network of passive components arraged as a low pass filter.Not only it provides attenuation of EMI energy conducted in power line,but also contributes significantly to the control of radiated EMI.The EMI power line filter is a primary tool available to the designed of electronic equipment for EMC design.
