AlpSemi Secures €17 Million to Advance Wide-Bandgap Power Switches for AI Data Centers
French semiconductor startup AlpSemi has raised €17 million ($19.5 million) in a funding round led by Yotta Capital, with participation from SE Ventures, Navitas Semiconductor, and Cycle Group. The investment marks a significant step in the development of next-generation power switches designed to meet the surging energy demands of AI data centers and electrical grids.
Founded in 2024 by CEO Frédéric Dupont and CTO Fabrice Letertre, the Grenoble-based company specializes in wide and ultra-wide bandgap semiconductor power switches. These materials offer superior energy efficiency compared to traditional silicon, enabling enhanced performance in environments where power constraints are critical. The technology is particularly relevant for 800V direct current AI data centers and solid-state circuit breakers used in residential and commercial buildings.
The company stated that the fresh capital will accelerate the commercialization of its power switches, which are purpose-built for solid-state circuit breaker applications. As AI infrastructure scales globally, the need for more efficient power protection and conversion architectures has become a pressing industry challenge. AlpSemi’s approach aims to address this by redefining power protection technologies through scalable semiconductor solutions.
“This financing positions AlpSemi to emerge as a leading global industrial player in power electronics,” said Dupont. “Our ambition is clear: accelerate the semiconductor roadmap required to enable the large-scale deployment of solid-state circuit breakers. In doing so, we are contributing to safer, smarter, and more efficient power protection and conversion architectures globally.”
Letertre added that the company’s end-to-end engineering approach allows it to move beyond incremental improvements. “Our wide and ultra-wide bandgap technologies are inherently scalable across the entire semiconductor value chain, enabling a fast solid-state circuit breaker market development,” he said.
The investment comes at a time when data center operators are increasingly focused on improving energy efficiency and reducing power losses, particularly as high-performance computing and AI workloads drive up electricity consumption. AlpSemi’s technology could play a pivotal role in enabling more efficient power distribution within next-generation facilities, potentially lowering operational costs and supporting sustainability goals across the industry.
