Infineon Technologies and NVIDIA to Revolutionize Power Delivery Architecture for AI Data Centers
Infineon Technologies AG is set to revolutionize the power delivery systems for future AI data centers in collaboration with NVIDIA.
The two companies are jointly developing a cutting-edge architecture based on 800 V high-voltage direct current (HVDC) for central power generation, significantly enhancing energy-efficient power distribution across AI-driven infrastructures.
Innovation in Power Delivery
The new HVDC architecture will allow for more efficient power conversion directly at the AI chip, specifically Graphics Processing Units, or GPUs, within the server board.
This innovation addresses the growing demands for power in AI data centers, where racks will require power outputs of one megawatt (MW) or more by the end of the decade. As AI data centers increasingly rely on 100,000+ GPUs, the need for efficient power distribution becomes critical.
Infineon is a power conversion expertise in all the key semiconductor materials such as silicon (Si), silicon carbide (SiC), and gallium nitride (GaN).
The partnership with NVIDIA allows the companies to speed up the design of centralized HVDC architectures, setting the ground for high-density multiphase power delivery systems that will greatly enhance reliability and efficiency.
Impact on AI Infrastructure
This shift to centralized power systems will optimize the limited space within server racks. In traditional AI data center architectures, power is supplied through numerous power supply units (PSUs) decentralized across racks.
With the new architecture, power distribution will become more efficient, utilizing fewer conversion stages and optimizing space while supporting higher voltage levels for greater power efficiency.
As AI workloads continue to scale and demand for high-performance computing (HPC) infrastructure grows, the 800 V HVDC system architecture promises to be a game-changer. The approach not only reduces energy consumption but also supports sustainability efforts within data centers by providing a more energy-efficient power system across the entire facility.
Adam White, Division President of Power & Sensor Systems at Infineon, said, “Infineon is driving innovation in artificial intelligence.”
He added, “The combination of Infineon's application and system know-how in powering AI from grid to core, combined with NVIDIA’s world-leading expertise in accelerated computing, paves the way for a new standard for power architecture in AI data centers to enable faster, more efficient and scalable AI infrastructure.”

Future Outlook and Scaling Potential
The future of AI data center power systems lies in this centralized, high-density power approach, which will increase the scalability and performance of AI infrastructure while lowering costs and energy consumption.
Infineon is poised to maintain a central role in this transformation, offering products designed for scalable AI infrastructure that support the HVDC architecture and DCDC multiphase solutions for hyperscalers and AI data center operators.
