NVIDIA Partners with Navitas to Develop 800V HVDC Data Center Technology

TORRANCE, Calif., May 21, 2025 — Navitas Semiconductor (Nasdaq: NVTS) announced a strategic agreement with NVIDIA (Nasdaq: NVDA) to create a new generation of 800V HVDC architecture for data centers. This partnership supports NVIDIA’s ‘Kyber‘ rack-scale systems, which power high-performance GPUs like the Rubin Ultra. The new technology is designed to facilitate 1 MW IT racks, bringing significant improvements over traditional 54V systems.

Key advantages of this 800V HVDC architecture include a 45% reduction in copper wire thickness, up to a 5% enhancement in end-to-end power efficiency, and a 70% decrease in maintenance costs. By shifting to this new design, NVIDIA aims to overcome current limitations in traditional systems that can handle only a few hundred kilowatts due to power density constraints.

Navitas will leverage its GaNFast™ and GeneSiC™ power semiconductors in this collaboration. The GaNSafe™ power integrated circuits (ICs) provide advanced protection features, while GeneSiC’s proprietary trench-assisted planar technology enhances performance. Recent achievements from Navitas include the first 8.5 kW AI data center power supply with 98% efficiency and a 12 kW power supply unit showcased at a tech exhibition.

This partnership signifies a technological shift as modern AI applications increasingly demand greater power. Traditional data centers often struggle with power delivery, requiring bulky copper components that create inefficiency. The implementation of 800V HVDC directly addresses this issue by simplifying the power architecture and minimizing losses.

With these innovations, NVIDIA’s 800V HVDC system is set to improve overall efficiency by 5%, reduce maintenance costs significantly, and lower cooling costs thanks to a more direct power delivery method. According to Gene Sheridan, CEO and co-founder of Navitas, “We are proud to collaborate with NVIDIA on this transformative architecture, which represents the future of data center power solutions.”
