Prognostic capability evaluation of power electronic modules in transportation electrification and vehicle systems

Health management and reliability are fundamental part of the design and development cycle of the power electronic products. This paper presents the study and investigation about the prognostic and health management of power electronic IGBT module. To achieve this aim, a fusion approach has been introduced. In addition, for the physic based part of approach, a thermal model is used to predict temperatures of inaccessible locations within the power module. Then by employing the rainflow algorithm, the remaining life of the power electronic IGBT module has been determined.
