Claim 3:
4. The method of claim 1, wherein in combination with the experiment measurement result of the IGBT physical model parameter, the IGBT physical model parameter is first corrected according to the dynamic and static features that are only affected by a single parameter, and then the IGBT physical model parameter is sequentially corrected starting from a dominant parameter according to the dynamic and static features affected by a coupling of multiple IGBT physical model parameters, and a temperature coefficient of the IGBT physical model parameter is corrected according to the variation of the dynamic and static features under different temperatures, and at last, a correction result of the IGBT physical model parameter under different temperatures is obtained and the extraction of the model parameter is finished.
