| 摘 要： | 针对在屏蔽室内进行电磁兼容测试时遇到的电磁干扰问题,通过实验判断出干扰主要来自屏蔽室电源滤波器的漏电流和地环路感应的噪声电压。本文重点分析了这两个干扰源对测试系统产生干扰的机理,在此基础上给出了解决漏电流干扰和地环路干扰的措施。

| Abstract: | The electromagnetic compatibility(EMC) testing system is interfered while used in a shielding chamber.The conclusion that the inference source is leakage current of power filter and noise voltage induced by ground loop is obtained by experiments.Then,the mechanism of leakage current interference and ground loop interference is analyzed.At last,the method of suppressing electromagnetic interference is presented in this paper. |
