IGBT module is the core component of the train traction converter, its life prediction technology is an important basis for the prognostic and health management of the whole train. In this paper, the current and voltage of IGBT module in CRH,5, EMUs were extracted by hardware-in-the-loop simulation method. Then, the lifetime related simulation and calculation were carried out.The calculation results showed that the lifetime of IGBT module in inverters lower than in pulse rectifier, module main terminal, chip and DBC soldering layer would be early signs of failure. This method provided a basis for accurately evaluating the lifetime of IGBT module in rail transit.
