Abstract

EMC debugging of power electronics systems depends heavily on experience of specialists due to the complex mechanisms of EMC. In this paper, time domain approach is utilized instead of conventional frequency domain method to identify noise propagation path. A proposed test mode lets all the upper or lower switches of the converter legs turn on and off with 50% fixed duty ratio at the same time. It is called common mode test mode. Because there is no significant functional current established, the differential mode noise is minimized and the remaining common mode noise and the mixed mode noise are maximized. Therefore, the common mode noise in this test mode gives its upper boundary of EMI level when the system is normal operated. A motor drive system is applied to show how this test mode works.
