In every electric powertrain, the drive inverter is a key component. When testing inverters, the main challenge is to increase test quality and test depth without increasing test effort, while at the same time the scope of the inverter functionality is increasing, and development times are becoming shorter.

A new method, based on a Power-Hardware-in-the-Loop topology, supports a systematic test approach. Test cases and virtual components form a library to serve different test cases on component level, system-level and vehicle level.

In this free webinar, AVL‘s Horst Hammerer explains this concept applied to an electric drive inverter test environment, where a “digital copy” of an e-motor supports numerous inverter test scenarios along with the inverter R&D phase.

Key topics and takeaways:

• Power electronics – a key component in e-drives
• Inverter test coverage comparison (R&D)
• Benefits of Power-HiL based inverter testing
• Inverter test system layout with e-motor emulator
