AlpSemi has successfully completed a €17 million funding round led by Yotta Capital, with participation from SE Ventures, Navitas Semiconductor, and Cycle Group. The financing will support the industrialization and commercial scale-up of AlpSemi’s next-generation semiconductor power switches designed for solid-state circuit breakers (SSCBs) targeting residential and commercial buildings as well as emerging 800 V DC AI data center power architectures.
The company is developing semiconductor technologies intended to enable a transition from traditional electromechanical protection systems toward fully solid-state, digitally controlled power distribution and protection networks. The funding is expected to accelerate both product commercialization and the expansion of AlpSemi’s semiconductor roadmap.
According to Chief Executive Officer Frédéric Dupont, the financing represents an important milestone in AlpSemi’s ambition to become a major industrial player in power electronics. The company’s strategy focuses on advancing semiconductor technologies required for the large-scale deployment of solid-state circuit breakers, which are expected to play an increasingly important role in future electrical infrastructure.
AlpSemi’s technology strategy spans semiconductor materials, device architectures, and system-level integration, creating a vertically integrated platform designed to address challenges associated with next-generation power protection and power conversion systems.
Chief Technology Officer Fabrice Letertre noted that the company’s approach extends beyond incremental device improvements by leveraging both wide-bandgap and ultra-wide-bandgap semiconductor technologies. These technologies are intended to provide a scalable foundation for future generations of solid-state circuit breaker products across multiple voltage classes and application areas.
SSCBs represent a significant evolution in electrical protection systems by replacing mechanical interruption mechanisms with semiconductor-based switching and digital control. Compared with conventional electromechanical breakers, SSCBs can provide:
- Real-time monitoring, control, and protection
- Faster fault response and system protection
- Improved energy efficiency
- Higher reliability in both AC and DC systems
- Enhanced scalability for modern electrified infrastructures
The technology is increasingly relevant as electricity demand grows due to artificial intelligence workloads, electrification, distributed energy resources, and the adoption of direct current (DC) power architectures.
Investors highlighted the growing demand for advanced power protection technologies driven by electrification, AI infrastructure expansion, and energy efficiency requirements.
Yotta Capital emphasized that AlpSemi’s technology platform addresses critical challenges associated with next-generation electrical infrastructure and aligns with broader investment themes focused on low-carbon industrial technologies.
SE Ventures noted that widespread adoption of SSCBs will be a key enabler of the digitalization of electrical distribution networks and viewed AlpSemi as representative of a new generation of industrial technology companies combining semiconductor innovation with strong market demand.
AlpSemi has already launched its first commercial product, the AS800 semiconductor power switch, designed for solid-state miniature circuit breakers operating in 110 V and 230 V electrical systems.
Key attributes of the AS800 include:
- High power density
- Compact system integration
- Support for distributed energy resources
- Enhanced flexibility for modern electrical networks
The product has been developed through a global supply chain involving multiple international partners and is positioned for large-scale industrial deployment. The newly raised capital will support expanded commercialization activities.
While the AS800 serves residential and commercial applications, AlpSemi’s longer-term roadmap extends into higher-voltage power protection systems, including 800 V DC architectures being developed for next-generation AI data centers.
As AI infrastructure scales, data center operators are increasingly exploring high-voltage DC distribution to improve power conversion efficiency and reduce energy losses. These architectures require advanced protection technologies capable of handling higher voltages, faster fault isolation, and increased power density.
Navitas Semiconductor CEO Chris Allexandre noted that the transition toward 800 V DC power systems will require new approaches to power distribution and protection. He highlighted AlpSemi’s technology platform as being specifically designed to address these emerging requirements, supporting intelligent power distribution systems for energy-intensive AI computing environments. Navitas will support AlpSemi both as an investor and strategic partner.
The funding positions AlpSemi at the intersection of several major industry trends:
- Electrification of buildings and industry
- Digitalization of electrical distribution systems
- AI-driven growth in data center power demand
- Adoption of 800 V DC architectures
- Expansion of distributed energy resources
- Increased focus on energy efficiency and grid modernization
By focusing on semiconductor-enabled solid-state protection technologies, AlpSemi aims to become a key enabler of next-generation electrical infrastructure spanning residential, commercial, industrial, and AI data center markets.
