The IGBT health evaluation of power semiconductor devices is usually based on the threshold evaluation method, which is usually a single characteristic parameter evaluation system. This kind of evaluation method cannot reflect the internal correlatio

The base-plate solder fatigue of the IGBT module is one of the failures of the wind power converter; however, the existing health condition monitoring method based on infrared thermography is difficult to be applied to the actual applications. In thi
