NVIDIA and Navitas Team Up for Advanced 800V HVDC Power Architecture

TORRANCE, Calif., May 21, 2025 (GLOBE NEWSWIRE) — Navitas Semiconductor Corp (Nasdaq: NVTS) has announced its partnership with NVIDIA (Nasdaq: NVDA) to develop an innovative 800V HVDC architecture aimed at enhancing power delivery for data centers. This collaboration will support NVIDIA’s new ‘Kyber’ rack-scale systems that provide power to their GPUs, such as the Rubin Ultra.

The new 800V HVDC architecture is set to allow for IT racks operating at 1 MW and beyond, which presents notable advantages over the current 54V systems. Among these benefits are a 45% reduction in copper wire thickness, a 5% improvement in overall power efficiency, a 70% decrease in maintenance costs, and lower cooling expenses.

Navitas will leverage its GaNFast™ and GeneSiC™ power semiconductor technologies, which include GaNSafe™ power ICs designed with advanced protection features. These innovations were validated by the company’s recent successes, including the first 8.5 kW AI data center power supply achieving 98% efficiency.

“We are proud to be selected by NVIDIA to collaborate on their 800 HVDC architecture initiative,” said Gene Sheridan, CEO of Navitas. He emphasized that their latest innovations will help meet the rising energy needs of AI data centers and enhance reliability.

The shift to an 800V system addresses significant efficiency challenges faced in current data center architectures, which often hit physical limits around 200 kW due to high copper content and decreasing efficiency. The new design aims to directly connect vast amounts of power to IT systems, ultimately facilitating faster and more reliable data processing.

As the demand for AI computation continues to surge, this partnership positions both NVIDIA and Navitas to carve a crucial niche in the evolving energy infrastructure landscape.
