Abstract: Aiming at the problems of the low accuracy and low repeatability of the test results caused by the nonstandard testplan in the present rolling stock apparatus electromagnetic compatibility (EMC) test, a certain type of traction converter was taken, the EMC elements such as potential interference sources, sensitive signals and interference coupling paths of the traction converter were analyzed and summarized. Based on this, the test plan of all the necessary EMC test items based on EN50121 rail standards were described. A kind of EMC test bench was designed to simulate the electromagnetic boundary environment of a traction converter. The results indicate that by analyzing the EMC elements of a certain type traction converter and clarifying the implementation object and operation details of each EMC test item, the effectiveness and repeatability of EMC test are guaranteed.

Key words: rail; traction converter; electromagnetic compatibility(EMC); EMC elements; test bench
