As one of the ideal switching devices in the field of power electronics, IGBT has been widely used in many fields. However, due to the long-term operation of IGBT in high voltage, high current and high frequency switching state, IGBT power consumption and junction temperature fluctuate frequently, which leads to temperature rise and thermal stress deformation, and ultimately leads to IGBT device fatigue aging. Based on the electrothermal model of IGBT and rain flow method are used to evaluate the fatigue aging of IGBT module. Finally, the statistical characteristics of junction temperature load are obtained and the life prediction of IGBT module was completed.
