Infineon Technologies AG, a world leader in semiconductor solutions for power systems, and SolarEdge Technologies, Inc., a global leader in smart energy, announced a collaboration to advance SolarEdge’s Solid-State Transformer (SST) platform for next-generation AI and hyperscale data centers. The collaboration focuses on the joint design, optimization and validation of a modular 2-5 megawatt (MW) SST building block. It combines advanced silicon carbide (SiC) switching technology from Infineon with SolarEdge’s proven power-conversion and control topology set to deliver >99% efficiency, supporting the global shift towards high-efficiency, DC-based data center infrastructure.
The Solid-State Transformer technology is well positioned to play a crucial role in future, highly efficient 800 Volt direct current (VDC) AI data center power architectures. The technology enables end-to-end efficiency and offers several key advantages, including a significant reduction of weight and size, a reduced CO₂ footprint, and accelerated deployment of power distribution, among others, when connecting the public grid with data center power distribution. The SST under joint development will enable direct medium-voltage (13.8–34.5 kV) to 800–1500 V DC conversion.
“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.”
“The AI revolution is redefining power infrastructure,” said Shuki Nir, CEO of SolarEdge. “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 an unprecedented surge in global power demand, data center operators are seeking new ways to deliver more efficient, reliable, and sustainable power. Building on more than 15 years of leadership in DC-coupled architecture and high-efficiency power electronics, this development would enable SolarEdge to expand into the data-center market with solutions designed to optimize power distribution from the grid to the compute rack. This optimization relies on the efficient conversion of power, a challenge that semiconductor solutions from Infineon are addressing, enabling efficient power conversions from grid to core (GPU). With a focus on delivering reliable and scalable power systems based on all relevant semiconductor materials silicon (Si), silicon carbide and gallium nitride (GaN), Infineon is enabling reduced environmental footprint and lower operating costs for the AI data center ecosystem.
