Infineon and SolarEdge collaborate on high-efficiency power infrastructure for AI data centers
Infineon Technologies AG of Munich, Germany and smart energy technology firm SolarEdge Technologies Inc of Milpitas, CA, USA are collaborating 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 2–5MW SST building block. It combines Infineon’s silicon carbide (SiC) switching technology 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 positioned to play a crucial role in future, highly efficient 800V direct current (VDC) AI data-center power architectures, it is reckoned. The technology enables end-to-end efficiency and offers key advantages, including a significant reduction in 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 (13.8–34.5kV) to 800–1500V DC conversion.
“Collaborations like this are key to enabling the next generation of 800V DC data-center power architectures and further driving decarbonization,” says Infineon’s chief marketing officer Andreas Urschitz. “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,” he adds.
“The AI revolution is redefining power infrastructure,” notes SolarEdge’s CEO Shuki Nir. “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,” he adds. “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 seeking new ways to deliver more efficient, reliable and sustainable power, notes Infineon. Building on more than 15 years of work 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 Infineon is 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 says that it is enabling reduced environmental footprint and lower operating costs for the AI data-center ecosystem.
