摘　　要：简述了低压电源电磁干扰及浪涌综合防护装置的原理 (包括浪涌抑制、射频干扰滤波、电压箝位、高频干扰滤波等 4个环节 )、抗差 (共 )模干扰试验和仿真分析、以及插入损耗测试。仿真与试验波形虽有差异 ,但均表明该装置能有效抑制差 (共 )This paper presents an abstract introduction on the theory of the multiple device (including surge suppression、radio filter、voltage clamping and high frequency interference filter and so on) and experiment of differential mode and common mode interference. At the same time we have finished insertion loss test and have done a simulation on the device with ATPDraw . Although there is a difference between the simulation and experiment curve, both of them prove that the device can effectively suppress differential mode and common mode interference.
