French AlpSemi Secures €17 Million in Funding

en.Wedoany.com Reported - French startup AlpSemi has completed a €17 million (approximately $19.5 million) funding round to develop next-generation power switches for AI data centers and power grids. The round was led by Yotta Capital, with participation from SE Ventures, Navitas Semiconductor, and Cycle Group.

Founded in 2024 by CEO Frédéric Dupont and CTO Fabrice Letertre, the Grenoble-based startup focuses on the development of wide-bandgap and ultra-wide-bandgap semiconductor power switches. Compared to traditional silicon materials, wide-bandgap and ultra-wide-bandgap materials offer higher energy efficiency and better performance in energy-constrained environments.

The funds raised will be used to drive the commercialization of these power switches. Specifically, the switches are designed for solid-state circuit breakers in residential and commercial buildings, as well as for 800V DC AI data centers.

Dupont stated that this funding positions AlpSemi to become a leading global industrial player in power electronics, with the goal of accelerating the semiconductor roadmap to enable large-scale deployment of solid-state circuit breakers, thereby contributing to safer, smarter, and more efficient power protection and conversion architectures worldwide.

Letertre added that the end-to-end engineering approach allows the company to go beyond incremental improvements and fundamentally redefine power protection technology. The wide-bandgap and ultra-wide-bandgap technology is inherently scalable across the entire semiconductor value chain, which will accelerate the growth of the solid-state circuit breaker market.
