Analysis of field of temperature of power electronic systems in COMSOL MULTIPHYSICS environment

The paper deals with analysis of temperature field in power electronic devices using COMSOL MULTIPHYSICS software. It includes relevant problem of designing, specifically a power semiconductor converter. Till now, there has been one-dimensional interpretation of analysis considering heat transfer by conduction. Presented method results directly from differential equations of system heat balance, whereby heat transfer by conduction, flow and radiation is considered. The results can be animated in 3D view which enables analyzing the space-division switching network in power electronic device
