Infineon Technologies AG is developing a next-generation AI server rack power supply architecture based on 800 V HVDC, which is expected to revolutionize the power supply of AI data centers, enabling them to efficiently address the rapidly increasing power demand while achieving sustainability goals.

Infineon announced on the 17th that it is introducing the next-generation AI data center power supply architecture centered on the industry's first 800V HVDC (high-voltage direct current) distribution system in collaboration with NVIDIA.

The new system dramatically improves power distribution efficiency and reliability by minimizing power conversion stages from the grid to the AI chips (GPUs) on the server board.

Infineon is accelerating its HVDC architecture roadmap, combining high-density multiphase solutions with its expertise in silicon (Si), silicon carbide (SiC) and gallium nitride (GaN) power semiconductors. This will minimize power losses in server racks and provide a next-generation power semiconductor standard that can meet the power demand of more than 1MW per IT rack by 2030.

The existing distributed power supply structure distributed power to multiple PSUs (power supply units), but the 800V HVDC centralized distribution system optimizes the limited space of the server rack. By reducing power conversion stages and high-voltage power distribution, it ensures the power capacity and stability required for high-performance AI workloads.

“Infineon’s power conversion know-how and NVIDIA’s accelerated computing expertise will enable faster, more efficient, and scalable AI infrastructure,” said Adam White, head of Infineon’s Power and Sensor Systems business unit.

“The 800V HVDC architecture will set a new standard for sustainable AI data centers by combining energy efficiency and reliability,” said Gabriele Gola, vice president of systems engineering at NVIDIA.

The 800V HVDC power supply architecture developed through this collaboration contributes to optimizing energy consumption and reducing carbon emissions. It is drawing attention from the industry as it can efficiently address the rapidly increasing power demand of AI data centers while achieving sustainability goals.

Infineon and NVIDIA plan to start prototype verification in the second half of 2025 and flesh out the commercialization roadmap in 2026. This innovation, which combines high-quality power semiconductors and advanced power distribution technology, is expected to establish itself as the future standard for AI server rack power supply.
