SolarEdge Technologies and Infineon Technologies announced a partnership to develop SolarEdge’s Solid-State Transformer (SST) platform for hyperscale data centers and next-generation AI. The combined design, optimization, and validation of a modular 2–5 megawatt (MW) SST building block is the main goal of the partnership.
It supports the global transition to high-efficiency, DC-based data center infrastructure by combining Infineon’s cutting-edge silicon carbide (SiC) switching technology with SolarEdge’s proven power-conversion and control architecture set to offer >99% efficiency.
Future highly efficient 800 Volt direct current (VDC) AI data center power architectures are expected to heavily rely on Solid-State Transformer technology.
When connecting the public grid with data center power distribution, the technology allows for end-to-end efficiency and offers a number of important benefits, such as a substantial decrease in weight and size, a smaller carbon footprint, and an expedited deployment of power distribution, among others.
Direct medium-voltage (13.8–34.5 kV) to 800–1500 V DC conversion will be possible with the SST under cooperative development.
Key Highlights Include:
- The development of extremely effective next-generation Solid-State Transformer (SST) technology for AI and hyperscale data centers is being advanced by Infineon and SolarEdge.
- The new SST reduces size, weight, and CO2 emissions by enabling direct medium-voltage to 800–1500V DC conversion with over 99% efficiency.
- The partnership supports sustainable, scalable power infrastructure and further growth into the AI Data Centers industry by fusing Infineon’s semiconductor innovation with SolarEdge’s DC experience.
