Spatial Electro-Thermal Modeling and Simulation of Power Electronic Modules

In this work, the spatial electro-thermal modeling and simulation of power electronic modules is discussed. It is shown how physical and mathematical modeling techniques can be combined to obtain a compact time-efficient electro-thermal simulation framework for power electronic modules. The accuracy of the modeling framework is demonstrated based on experiments. It can be used for the fast calculation of the temperature distribution of a power module in an electric vehicle over driving cycles. The spatial temperature information allows to effectively estimate the lifetime of the power module.
