Infineon Technologies is developing a next-generation AI server rack power supply architecture based on 800V 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 a 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 steps from the grid to the AI chips (GPUs) on the server board.

Infineon is accelerating its HVDC architecture roadmap, leveraging its expertise in silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) power semiconductors to combine high-density, multiphase solutions. This will minimize power losses within server racks and establish a next-generation power semiconductor standard capable of meeting the anticipated power demand of over 1MW per IT rack by 2030.

The existing distributed power supply structure distributed power to multiple power supply units (PSUs), but the 800V HVDC centralized distribution system optimizes the limited space of server racks. 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 combine to 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. This approach is attracting attention from the industry as it can efficiently address the rapidly increasing power demands of AI data centers while achieving sustainability goals.

Infineon and NVIDIA plan to begin prototype validation in the second half of 2025 and finalize their commercialization roadmap in 2026. This innovation, combining high-quality power semiconductors with advanced power distribution technology, is expected to establish itself as the future standard for power supply in AI server racks.
