Infineon Technologies AG and SolarEdge Technologies, Inc. have announced a strategic collaboration to advance SolarEdge’s Solid-State Transformer (SST) platform for next-generation artificial intelligence (AI) and hyperscale data centers.
The partnership focuses on the co-design, optimization, and validation of a modular 2–5 megawatt (MW) SST building block. This platform combines Infineon’s advanced silicon carbide (SiC) switching technology with SolarEdge’s high-efficiency power conversion and control topology. The result is an SST solution delivering greater than 99 percent efficiency, supporting the transition to high-efficiency, DC-based data center infrastructure.
Solid-State Transformer technology is emerging as a foundational element in future 800-volt direct current (VDC) data center power architectures. It offers several key advantages, including significantly reduced size and weight, a lower CO₂ footprint, and faster deployment of power distribution infrastructure. The SST being jointly developed will enable direct medium-voltage (13.8–34.5 kV) to 800–1500 V DC conversion, streamlining the connection between public utility grids and high-performance compute environments.
“Collaborations like this are key to enabling the next generation of 800-volt DC data center power architectures and further driving decarbonization,” said Andreas Urschitz, Chief Marketing Officer at Infineon. “With high-performance SiC technology from Infineon, SolarEdge’s proven capabilities in power management and system optimization are enhanced, creating a strong foundation for the efficient, scalable, and reliable infrastructure demanded by AI-driven data centers.”
Shuki Nir, CEO of SolarEdge, added: “The AI revolution is redefining power infrastructure. It is essential that the data center industry is equipped with solutions that deliver higher levels of efficiency and reliability. SolarEdge’s deep expertise in DC architecture uniquely positions us to lead this transformation. Collaborating with Infineon brings world-class semiconductor innovation to our efforts to build smarter, more efficient energy systems for the AI era.”
As AI infrastructure drives a surge in global power demand, data center operators are increasingly focused on achieving greater efficiency, reliability, and sustainability. This collaboration builds on SolarEdge’s 15 years of leadership in DC-coupled architecture and high-efficiency power electronics, enabling it to expand into the data center sector with solutions optimized for grid-to-rack power distribution.
Infineon’s broad portfolio of semiconductor solutions—including technologies based on silicon, silicon carbide, and gallium nitride—is enabling power systems that reduce environmental impact and operating costs across the AI data center ecosystem.
