NVIDIA and Navitas Collaborate on 800V HVDC Architecture for AI Data Centers

Modern AI data centers require massive amounts of power, often reaching gigawatts. Traditional 54V in-rack power distribution systems are limited in their ability to handle these demands efficiently. NVIDIA's 800V HVDC architecture directly converts grid power to 800V at the data center perimeter, eliminating multiple conversion steps and maximizing efficiency and reliability.

Navitas Semiconductor's GaNFast™ and GeneSiC™ technologies play a crucial role in this architecture. These technologies enable higher switching speeds, better thermal performance, and longer lifespans compared to traditional silicon solutions. Navitas' GaNSafe™ power ICs integrate control, drive, sensing, and protection features, ensuring reliability and robustness.

The collaboration has already produced significant results, including the development of an 8.5 kW AI data center power supply with 98% efficiency and a 12 kW PSU presented at Computex. These advancements demonstrate the potential for further innovation in AI data center power delivery.

This shift towards 800V HVDC architecture represents a significant advancement in data center technology, addressing the limitations of existing systems and paving the way for more efficient and sustainable AI infrastructure.
