Boosting Efficiency, Reliability And Affordability Of EV-Drivetrain Power Modules

by André Christmann and David Levett, Infineon Technologies North America, El Segundo, Calif., How2Power Today, Jul 15 2017

Focus:
The development of EV drive trains for private-car and commercial, construction and agricultural vehicles is demanding reductions in the cost of drivetrain components including power transistors/power modules used in EV traction inverters. This article describes how improvements in IGBT device design and module packaging associated with Infineon’s EDT2 IGBT/diode chipset and its HybridPACK Drive package enable reductions in switching and conduction losses, greater ability to withstand thermal stresses, and use of smaller, lighter baseplates. In the targeted EV applications, these improvements can be leveraged either to create IGBT modules with smaller size or higher current rating.

What you’ll learn:

• How to understand the benefits of specific improvements in IGBT device design and IGBT module design in EV traction inverter applications
