SolarEdge Technologies has partnered with Infineon Technologies to advance a solid-state transformer (SST) platform targeting artificial intelligence (AI) and hyperscale data center applications. According to both companies, the collaboration aims to jointly design, optimize, and validate a modular 2 to 5 megawatt SST building block. The system combines advanced silicon carbide (SiC) switching technology from Infineon with SolarEdge’s power conversion and control topology to deliver greater than 99 percent efficiency for high-efficiency, direct current (DC)-based data center infrastructure.
The SST technology is designed to support future 800 volt DC data center power architectures, enabling end-to-end efficiency and several operational benefits. These include significantly reduced weight and size, a lower carbon footprint, and faster deployment of power distribution infrastructure for data centers. The jointly developed SST module is engineered for direct medium-voltage input (13.8 to 34.5 kilovolts) and conversion to 800 to 1500 volt DC, facilitating direct connection from the grid to data center distribution systems.
Infineon’s high-performance SiC devices are a key feature of the solution, supporting efficient power conversion from grid level to core compute elements. The effort focuses on increasing reliability and scalability in data center power systems through a mix of semiconductor technologies including silicon, SiC, and gallium nitride (GaN).
Shuki Nir, CEO of SolarEdge, stated, “The AI revolution is redefining power infrastructure,” and continued, “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.”
Andreas Urschitz, Chief Marketing Officer at Infineon Technologies, added, “Collaborations like this are key to enabling the next generation of 800 Volt DC data-center power systems and further driving decarbonization. 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.”
SolarEdge’s entry into the data center market leverages its experience in DC-coupled architectures and high-efficiency power electronics, intending to optimize distribution from public grid through to the compute rack. Infineon reports that its semiconductor portfolio aims to help reduce environmental impact and operational costs for large-scale AI data centers.
