Presented at the STAR Global Conference 2012

The power electronics system of an electric vehicle is a critical part of the electric drivetrain, controlling the electrical power delivery between the battery system and the electric motors.

IGBTs (insulated gate bipolar transistors) are three-terminal power semiconductor device primarily used as an electronic switch combining high efficiency and fast switching. IGBTs are a key component in the power electronics system, and this presentation will give specific instructions for effectively and efficiently simulating the thermal performance of IGBTs in STAR-CCM+.  Particular aspects will include: • The appropriate geometric detail. 

• Material properties. 

• Simulation setup. 

• Utilization of vendor data. 

• Key output results.
