NVIDIA Selects Navitas to Collaborate on Next Generation 800 V HVDC Architecture

Navitas Semiconductor (NVTS) is collaborating with NVIDIA (NVDA) on its next-generation 800V HVDC architecture to support rack-scale AI systems, including those powering Rubin Ultra GPUs. NVIDIA's shift to 800V HVDC aims to improve power efficiency and scalability for AI workloads, reducing copper requirements by up to 45% and overall maintenance costs by 70% compared to traditional 54V systems, which are becoming unsustainable for modern AI data centers requiring gigawatts of power. Navitas' GaNFast and GeneSiC power technologies will be utilized to enable efficient power delivery from the grid to the GPU.

Analysis

Navitas Semiconductor (NVTS) has entered into a significant collaboration with NVIDIA (NVDA) to develop NVIDIA's next-generation 800V High-Voltage Direct Current (HVDC) power architecture for advanced AI data centers. This initiative is designed to support high-density 'Kyber' rack-scale systems, including those powering upcoming GPUs like the Rubin Ultra, and addresses the escalating power demands of AI workloads, which can reach gigawatt levels. NVIDIA's shift from traditional 54V systems, limited to a few hundred kilowatts, to an 800V HVDC architecture aims to substantially improve efficiency and scalability by directly converting 13.8 kV AC grid power. Key benefits highlighted include a potential 45% reduction in copper wiring thickness, up to a 5% improvement in end-to-end power efficiency, and a 70% decrease in maintenance costs due to fewer power supply unit failures. Navitas will leverage its GaNFast™ gallium nitride (GaN) and GeneSiC™ silicon carbide (SiC) power semiconductors, which are critical for this advanced power delivery. Navitas has demonstrated progressive innovation in this space, evidenced by its development of high-power density solutions such as a 4.5 kW CRPS achieving over 97% efficiency, an 8.5 kW AI data center power supply meeting 98% efficiency, and a newly presented 12 kW PSU. The company's GaNSafe™ and GeneSiC™ technologies offer enhanced reliability and performance, positioning Navitas as a key supplier in NVIDIA's strategy to build more robust and efficient AI infrastructure.
