The alliance underscores a critical shift towards more efficient, compact, and sustainable power solutions, directly addressing the escalating energy demands of modern AI workloads and laying the groundwork for exascale computing.

The partnership sees Navitas providing its cutting-edge GaNFast™ and GeneSiC™ power semiconductors to support Nvidia's 'Kyber' rack-scale systems, designed to power future GPUs such as the Rubin Ultra. This move is not merely an incremental upgrade but a fundamental re-architecture of data center power, aiming to push server rack capacities to 1-megawatt (MW) and beyond, far surpassing the limitations of traditional 54V systems. The implications are profound, promising significant improvements in energy efficiency, reduced operational costs, and a substantial boost in the scalability and reliability of the infrastructure underpinning the global AI boom.

The Technical Backbone: GaN, SiC, and the 800V Revolution

The core of this AI advancement lies in the strategic deployment of wide-bandgap semiconductors—Gallium Nitride (GaN) and Silicon Carbide (SiC)—within an 800V HVDC architecture. As AI models, particularly large language models (LLMs), grow in complexity and computational appetite, the power consumption of data centers has become a critical bottleneck. Nvidia's next-generation AI processors, like the Blackwell B100 and B200 chips, are anticipated to demand 1,000W or more each, pushing traditional 54V power distribution systems to their physical limits.

Navitas' contribution includes its GaNSafe™ power ICs, which integrate control, drive, sensing, and critical protection features, offering enhanced reliability and robustness with features like sub-350ns short-circuit protection. Complementing these are GeneSiC™ Silicon Carbide MOSFETs, optimized for high-power, high-voltage applications with proprietary 'trench-assisted planar' technology that ensures superior performance and extended lifespan. These technologies, combined with Navitas' patented IntelliWeave™ digital control technique, enable Power Factor Correction (PFC) peak efficiencies of up to 99.3% and reduce power losses by 30% compared to existing solutions. Navitas has already demonstrated 8.5 kW AI data center power supplies achieving 98% efficiency and 4.5 kW platforms pushing densities over 130W/in³.

This 800V HVDC approach fundamentally differs from previous 54V systems. Legacy 54V DC systems, while established, require bulky copper busbars to handle high currents, leading to significant I²R losses (power loss proportional to the square of the current) and physical limits around 200 kW per rack. Scaling to 1MW with 54V would demand over 200 kg of copper, an unsustainable proposition. By contrast, the 800V HVDC architecture significantly reduces current for the same power, drastically cutting I²R losses and allowing for a remarkable 45% reduction in copper wiring thickness. Furthermore, Nvidia's strategy involves converting 13.8 kV AC grid power directly to 800V HVDC at the data center perimeter using solid-state transformers, streamlining power conversion and maximizing efficiency by eliminating several intermediate AC/DC and DC/DC stages. GaN excels in high-speed, high-efficiency secondary-side DC-DC conversion, while SiC handles the higher voltages and temperatures of the initial stages.

Initial reactions from the AI research community and industry experts have been overwhelmingly positive. The partnership is seen as a major validation of Navitas' leadership in next-generation power semiconductors. Analysts and investors have responded enthusiastically, with Navitas' stock experiencing a significant surge of over 125% post-announcement, reflecting the perceived importance of this collaboration for the future of AI infrastructure. Experts emphasize Navitas' crucial role in overcoming AI's impending "power crisis," stating that without such advancements, data centers could literally run out of power, hindering AI's exponential growth.
