| Summary: | Four popular engineering power device lifetime evaluation models based on power cycling test was introduced.Aiming at the problem that these models ignore the complexity of power device packaging and actual working conditions, it was proposed that the power cycle test for life evaluation was more suitable to select the threshold based on device degradation rather than device failure, and finally the threshold setting method, fast power devices life evaluation formula and remaning life evaluation method for quickly completing the degradation evaluation based power cycle test under actual working conditions were provided. This method can quickly evaluate the lifetime of power devices with low cost in engineering practice. |
