Method for realizing conducted electromagnetic interference separation based on time domain measurement

The invention relates to a conducted electromagnetic interference separation technical method based on time domain measurement. According to the principle, time domain sampling is carried out on output signals of a linear impedance stabilization network, then software separation and frequency spectrum output of conducted interference are achieved through a numerical calculation method according todefinitions of differential mode interference and common mode interference, and finally evaluation of the conducted interference separation effect is completed through a test experiment. Compared with a general standard conducted interference test method, the method has the advantages that a digital oscilloscope is used to replace an expensive EMI receiver, special conducted interference separation network equipment is not needed, the hardware cost of a test system can be greatly reduced, and the method is suitable for conducted electromagnetic interference test and rectification. 本发明涉及一种基于时域测量的传导电磁干扰分离技术方法,其原理是通过对线性
