Abstract:
In traction applications HV-IGBTs are subjected to changing and particularly demanding climatic conditions. A new methodology is proposed to derive the chips’ mission profiles from realistic mission profiles of the railway vehicle and to more accurately assess the status of degradation or health of the IGBT modules. This will help to more precisely predict the remaining useful lifetime or schedule preventive maintenance of the railway traction converters.
