Infineon and NVIDIA collaborate on 800V power delivery for AI data centers

Infineon Technologies AG and NVIDIA are partnering to develop an 800 V high-voltage direct current (HVDC) power delivery architecture for AI data centers. The centralized system aims to distribute power more efficiently across data centers, converting power directly at the AI chip (GPU) within server boards. Infineon’s expertise in power conversion solutions, using silicon, silicon carbide, and gallium nitride, supports the development of this HVDC architecture.

The collaboration addresses the growing power demands of AI data centers, which are expected to exceed one megawatt per IT rack by the end of the decade. The HVDC architecture, combined with high-density multiphase solutions, is intended to set a new industry standard for power distribution systems.
Adam White, Division President of Power & Sensor Systems at Infineon, stated that the partnership with NVIDIA aims to establish a new power architecture standard for AI data centers. Gabriele Gorla, vice president of system engineering at NVIDIA, noted that the 800 V system supports energy-efficient power distribution, aligning with NVIDIA’s focus on sustainability and performance for AI workloads.
Currently, AI data centers use decentralized power supply units ...
