Abstract:
This work describes methods to determine ageing of IGBT power semiconductor modules. The relevant parameters for fatigue during operation are identified. Based on a standard model for end-of-life prediction of IGBT modules, a method for on-line estimation of deterioration under normal operation conditions is proposed. A test system to evaluate the proposed methods predicting power module degradation is presented.
