Annual return of the world’s leading power electronics event. Same depth as the 2026 edition — 650+ exhibitors showing the latest in SiC/GaN devices, power modules, and thermal management — with an extra year of progress on AI-era power delivery.

If you attended in 2026, come back to see what moved from prototype to production. If you didn’t, this is the one power electronics event that covers the full stack from discrete components to complete power conversion systems.
