Smart energy company, SolarEdge Technologies and semiconductor solutions for power systems, Infineon Technologies AG, today (5 November) 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, combining advanced silicon carbide (SiC) switching technology from Infineon with SolarEdge’s proven power-conversion and control topology set to deliver more than 99 per cent efficiency, supporting the global shift toward high-efficiency, DC-based data centre infrastructure.
The Solid State Transformer (SST) 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 is designed to enable end-to-end efficiency and offer 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 800–1500V DC conversion.
“The AI revolution is redefining power infrastructure,” said Shuki Nir, CEO of SolarEdge. “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.”
“Collaborations like this are key to enabling the next generation of 800 Volt DC data-centre power systems and further driving decarbonisation,” said Andreas Urschitz, chief marketing officer at Infineon Technologies. “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 drives an unprecedented surge in global power demand, data centres 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 (SiC) and gallium nitride (GaN), Infineon is enabling reduced environmental footprint and lower operating costs for the AI data centre ecosystem.
