**NVIDIA Taps Navitas’ GaN and SiC for Next-Gen AI Data Center Power**

**TORRANCE, CA – May 21, 2025** – NVIDIA (Nasdaq: NVDA) is partnering with Navitas Semiconductor (Nasdaq: NVTS) to develop a revolutionary 800V HVDC power architecture for its next-generation data centers. Navitas’ advanced GaNFast™ gallium nitride (GaN) and GeneSiC™ silicon carbide (SiC) power semiconductors have been selected to power NVIDIA’s ‘Kyber’ rack-scale systems that support demanding AI workloads, including those on the Rubin Ultra GPUs.

The collaboration aims to overcome the limitations of traditional 54V data center power systems, which struggle to efficiently deliver power to increasingly power-hungry AI infrastructure. NVIDIA’s new architecture converts the 13.8 kV AC grid power to 800 V HVDC at the data center perimeter using solid state transformers. This approach enables direct power to IT racks, minimizing conversion losses, reducing copper wiring requirements by up to 45%, and improving overall system efficiency.

“We are proud to be selected by NVIDIA to collaborate on their 800 HVDC architecture initiative. Our latest innovations in high-power GaN and SiC technologies have seen world firsts and have created new inflections into markets such as AI datacenters and electric vehicles”, said Gene Sheridan, CEO and co-founder of Navitas.

Navitas’ GaN and SiC technologies offer the high-speed, high-efficiency, and robust protection features essential for AI data centers. According to NVIDIA, the 800V HVDC architecture promises up to 5% improved end-to-end power efficiency, 70% lower maintenance costs due to fewer PSU failures, and significant reductions in cooling costs. This collaboration is seen as a critical step in enabling the next generation of AI infrastructure that demands immense processing power.
