摘　　要：随着开关电源广泛应用,其产生的电磁干扰(electromagnetic interference,EMI)也越来越得到人们的关注。EMI滤波器是抑制开关电源电磁干扰的有效方法,本文介绍了一款有源滤波和无源滤波相结合的混合型EMI滤波器,并通过CE102试验进行验证,说明滤波器的有效性。With the wide application of switching power supply,the electromagnetic interference produced by it has been paid more and more attention o EMI filter is an effective method to suppress electromagnetic interference of sw让ching power supply,this paper introduces a hybrid EMI filter which combines active filter and passive filter,and by the CE102 experiment,the validity of the filter is verified。
