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.
