Infineon Technologies AG and SolarEdge Technologies, Inc., based in Munich, Germany, and Milpitas, California, respectively, have announced a strategic collaboration aimed at advancing SolarEdge’s Solid-State Transformer (SST) platform for the next generation of AI and hyperscale data centers. The partnership will focus on the joint development, optimization, and validation of a modular 2-5 megawatt (MW) SST building block. By combining Infineon’s cutting-edge silicon carbide (SiC) switching technology with SolarEdge’s expertise in power-conversion and control systems, the collaboration is set to achieve over 99% efficiency. This will play a pivotal role in supporting the global transition to high-efficiency, DC-based data center infrastructure.
The Solid-State Transformer (SST) technology is poised to play a vital role in the future of highly efficient 800 Volt direct current (VDC) power architectures for AI data centers. This advanced technology ensures end-to-end efficiency and offers several significant benefits, including reduced weight and size, a smaller CO₂ footprint, and faster power distribution deployment. It also facilitates seamless integration between the public grid and data center power systems. The SST, currently under joint development, will enable efficient direct conversion from medium-voltage (13.8–34.5 kV) to 800–1500 V DC, supporting the evolving needs of modern data centers.
“Collaborations like this are pivotal in advancing the next generation of 800 Volt DC power architectures for data centers and accelerating the path to decarbonization,” said Andreas Urschitz, Chief Marketing Officer at Infineon. “By integrating Infineon’s high-performance SiC technology with SolarEdge’s proven expertise in power management and system optimization, we are establishing a robust foundation for the scalable, efficient, and reliable infrastructure needed by AI-driven data centers.”
“The AI revolution is reshaping power infrastructure,” said Shuki Nir, CEO of SolarEdge. “For the data center industry to keep pace, it’s crucial to implement solutions that offer superior efficiency and reliability. With SolarEdge’s extensive expertise in DC architecture, we are uniquely positioned to lead this transformation. Our collaboration with Infineon brings world-class semiconductor innovation to the forefront of our efforts to create smarter, more efficient energy systems for the AI era.”
As AI infrastructure drives an unparalleled increase in global power demand, data center operators are exploring new ways to deliver more efficient, reliable, and sustainable power solutions. Building on over 15 years of expertise in DC-coupled architecture and high-efficiency power electronics, this collaboration enables SolarEdge to expand its footprint in the data center market with solutions designed to optimize power distribution from the grid to the compute rack. This optimization hinges on the efficient conversion of power, a challenge that Infineon’s semiconductor solutions are addressing by enabling seamless power conversion from grid to core (GPU). By leveraging all relevant semiconductor materials silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) Infineon is helping reduce the environmental footprint and lower operating costs within the AI data center ecosystem.
