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.
