Smart energy company SolarEdge Technologies and semiconductor solutions provider Infineon Technologies AG have announced a strategic partnership to enhance SolarEdge’s Solid-State Transformer (SST) platform, targeting next-generation AI and hyperscale data centres. This collaboration merges Infineon’s advanced silicon carbide (SiC) switching technology with SolarEdge’s expertise in power conversion and control, aiming to achieve over 99% efficiency. The initiative supports the global shift towards high-efficiency, DC-based data centre infrastructure.
SST technology is set to become a cornerstone in future 800 Volt direct current (VDC) AI data centre power architectures. It promises to deliver end-to-end efficiency and offers significant advantages, such as reduced weight and size, a lower CO₂ footprint, and faster deployment of power distribution systems. The SST under development will facilitate direct medium-voltage (13.8–34.5 kV) to 800–1500V DC conversion, streamlining the connection between the public grid and data centre power distribution.
Shuki Nir, CEO of SolarEdge, stated, “The AI revolution is redefining power infrastructure. It is essential that the data centre 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.”
Andreas Urschitz, Chief Marketing Officer at Infineon Technologies, commented, “Collaborations like this are key to enabling the next generation of 800 Volt DC data-centre power systems and further driving decarbonisation. With high-performance SiC technology from Infineon, SolarEdge’s proven capabilities in power management and system optimisation are enhanced, creating a strong foundation for the efficient, scalable, and reliable infrastructure demanded by AI-driven data centres.”
As AI infrastructure accelerates global power demand, data centres are exploring new methods to achieve more efficient, reliable, and sustainable power solutions. With over 15 years of leadership in DC-coupled architecture and high-efficiency power electronics, SolarEdge is poised to expand into the data-centre market, optimising power distribution from grid to compute rack.
This optimisation depends on efficient power conversion, a challenge addressed by Infineon’s semiconductor solutions. By focusing on reliable and scalable power systems using silicon (Si), silicon carbide (SiC), and gallium nitride (GaN), Infineon contributes to a reduced environmental footprint and lower operating costs for the AI data centre ecosystem.
