[7 November 2025, Munich, Germany and Milpitas, California, USA] Infineon Technologies AG, a global leader in power semiconductors, and SolarEdge Technologies, a global leader in smart energy solutions, have announced a collaboration to advance the application of SolarEdge's Solid-State Transformer (SST) platform in next-generation artificial intelligence (AI) and hyperscale data centres. This partnership aims to jointly design, optimise, and validate a modular SST base unit ranging from 2 to 5 megawatts (MW). The platform combines Infineon's advanced silicon carbide (SiC) switching technology with SolarEdge's proven power conversion and control topologies to achieve conversion efficiencies exceeding 99%, supporting the global transition towards efficient DC-based data centre infrastructure.

SST technology is poised to play a pivotal role in future high-efficiency 800V DC AI data centre power architectures. The technology enables end-to-end efficient conversion and delivers significant advantages when connecting public grids to data centre power distribution systems. These include substantial reductions in weight and volume, lower carbon footprints, and accelerated deployment of power distribution systems. The jointly developed SST will directly convert medium voltage (13.8–34.5 kV) to 800–1500V DC.

Andreas Urschitz, Global Chief Marketing Officer at Infineon Technologies, stated: ‘Such collaborations are vital for realising next-generation 800V DC data centre power architectures and further advancing decarbonisation. Leveraging Infineon's high-performance SiC technology, SolarEdge's proven expertise in power management and system optimisation is further enhanced, laying a robust foundation to meet the demands of AI-driven data centres for efficient, scalable, and highly reliable infrastructure.’

With the rapid expansion of AI infrastructure driving unprecedented global electricity demand, data centre operators are actively seeking more efficient, reliable and sustainable power solutions. Leveraging over 15 years of pioneering expertise in DC-coupled architectures and high-efficiency power electronics, this new product development will propel SolarEdge into the data centre market, delivering solutions focused on optimising power distribution from the grid to the computer rack. This optimisation relies on efficient power conversion, a challenge effectively addressed by Infineon's semiconductor solutions, enabling efficient power conversion from the grid to the core (GPU). Infineon is committed to leveraging multiple key semiconductor materials, including silicon (Si), silicon carbide (SiC) and gallium nitride (GaN), to build reliable and scalable power systems. This approach supports the AI data centre ecosystem in reducing its environmental footprint while effectively lowering operational costs.
