French
semiconductor company AlpSemi has raised €17
million in a funding round led by Yotta Capital, with participation from SE Ventures, Navitas Semiconductor and Cycle Group. The financing will support the
industrialisation and commercial scale-up of the company’s semiconductor power
switches, which are designed for solid-state circuit breakers (SSCBs) in
residential and commercial buildings, as well as 800V direct current (DC) AI
data centres.
As global electricity demand continues
to grow, driven by AI workloads, electrification and the adoption of direct
current power architectures, the need for more efficient and intelligent power
protection systems is increasing. AlpSemi is developing semiconductor
technologies to support the transition from traditional electromechanical
circuit breakers to digitally controlled, semiconductor-based alternatives.
Solid-state circuit breakers are
designed to provide real-time control and protection of electrical systems
while improving efficiency, reliability and scalability across both AC and DC
power networks. The technology is expected to play an increasingly important
role in modern buildings, industrial facilities and data centres as energy
systems become more complex and power-intensive.
AlpSemi’s approach spans materials,
devices and systems, creating a vertically integrated platform for power
protection and conversion. The company’s semiconductor switches are designed to
integrate with existing power semiconductor ecosystems while supporting the
performance requirements of next-generation electrical infrastructure.
As part of this strategy, the company
has already launched its first product, AS800, a semiconductor power switch
designed for solid-state miniature circuit breakers operating in 110V and 230V
environments. According to AlpSemi, the product combines high power density
with a compact form factor while supporting distributed energy resources and
greater flexibility in modern electrical systems.
Developed through a global supply
chain and in collaboration with international partners, the AS800 is positioned
for industrial-scale deployment. The product represents the first step in
AlpSemi’s broader roadmap targeting high-voltage power protection systems,
including 800V DC architectures designed for AI data centres.
Frédéric Dupont, CEO of AlpSemi, said
the funding will help accelerate the development of solid-state circuit breaker
technology and support next-generation power protection and conversion systems.
With the new funding,
AlpSemi aims to accelerate the deployment of next-generation power protection
technologies across buildings, industrial applications and AI data centres.
