Power Semiconductors for a Variety of Electric Vehicles

Join Hitachi ABB Power Grids, Semiconductors, a leading developer and manufacturer of power semiconductors, for an overview of the newest power semiconductor trends and modules.

Date: September 11, 2020
Time: 10 AM EDT (7 AM PDT / 4:00 PM CEST)
Duration: 1 hour
Presented by:


In this presentation, our experts give an overview of various e-mobility applications and how they use power semiconductors. Attendees will see examples showing the use of power semiconductors, from a Formula E car using a RoadPak to deliver rapid acceleration on a race track, to a train powered by HiPaks that carries thousands of passengers for more than 20 years over many thousands of kilometers.

The examples demonstrate the experience and technology that Hitachi ABB Power Grids can offer in powering your e-mobility application. The presentation also includes a discussion of Gate units, which are becoming more and more important when driving high-speed, high-power SiC power semiconductor modules. Furthermore, it also includes look into future applications and trends such as e-aviation.

At the end of the session ABB's experts will be available to chat and to answer your questions.

Key Takeaways

  • Understand the various applications in e-mobility, their challenges and the best power semiconductor module for each
  • Learn how optimized gate units can boost the performance of a SiC power semiconductor module
  • Understand trends and see examples of future developments


Tobias Keller, VP, Global Head of Product Management, Hitachi ABB Power Grids
