Infineon and SolarEdge collaborate to advance high-efficiency power infrastructure for AI data centres
Infineon and SolarEdge Technologies, a global leader in smart energy, have announced a collaboration to advance SolarEdge’s Solid-State Transformer (SST) platform for next-generation AI and hyperscale data centres. The collaboration focuses on the joint design, optimisation and validation of a modular 2-5 megawatt (MW) SST building block. It combines advanced silicon carbide (SiC) switching technology from Infineon with SolarEdge’s proven power-conversion and control topology set to deliver >99% efficiency, supporting the global shift towards high-efficiency, DC-based data centre infrastructure.
The Solid-State Transformer technology is well positioned to play a crucial role in future, highly efficient 800 Volt direct current (VDC) AI data centre power architectures. The technology enables end-to-end efficiency and offers several key advantages, including a significant reduction of weight and size, a reduced CO₂ footprint, and accelerated deployment of power distribution, among others, when connecting the public grid with data centre power distribution. The SST under joint development will enable direct medium-voltage (13.8–34.5 kV) to 800–1500 V DC conversion.
As AI infrastructure drives an unprecedented surge in global power demand, data centre operators are seeking new ways to deliver more efficient, reliable, and sustainable power. Building on more than 15 years of leadership in DC-coupled architecture and high-efficiency power electronics, this development would enable SolarEdge to expand into the data-centre market with solutions designed to optimise power distribution from the grid to the compute rack. This optimisation relies on the efficient conversion of power, a challenge that semiconductor solutions from Infineon are addressing, enabling efficient power conversions from grid to core (GPU). With a focus on delivering reliable and scalable power systems based on all relevant semiconductor materials silicon (Si), silicon carbide and gallium nitride (GaN), Infineon is enabling reduced environmental footprint and lower operating costs for the AI data centre ecosystem.
