Power Semiconductors for the Future E-Mobility

9 Jun 2026

Speaker: Tobias Keller, Vice President, Head of Global Product Management, Portfolio & Marketing, Hitachi Energy

E‑mobility is accelerating and with it the expectations for faster charging, longer range, lighter drivetrains, and uncompromising safety. Power semiconductors sit at the heart of this transformation, defining how efficiently we convert energy from grid to battery and from battery to wheel.

This talk highlights the roadmap from today’s proven silicon carbide solutions, and what that means for traction inverters, onboard chargers, DC‑DC converters, and charging infrastructure. We will connect device physics, packaging, and reliability to real vehicle KPIs such as efficiency at partial load, lifetime, and total cost of ownership.

Discover how the next wave of power semiconductors will help make electric mobility more affordable and more sustainable.
