TORRANCE, Calif., Oct. 13, 2025 (GLOBE NEWSWIRE) -- Navitas Semiconductor (NASDAQ:NVTS), the industry leader in next-generation GaNFast™ gallium nitride (GaN) and GeneSiC™ silicon carbide (SiC) power semiconductors, announced progress in its development of advanced medium and high 800 VDC voltage GaN and SiC power devices to enable the 800 VDC power architecture announced by NVIDIA for next-generation AI factory computing platforms.

With the emergence of the ‘AI factory', a new class of data center purpose-built for large-scale, synchronous AI and high-performance computing (HPC) workloads, has introduced a set of power challenges. Traditional enterprise and cloud data centers, which rely on legacy 54 V in-rack power distribution, are unable to longer meet the multi-megawatt rack densities required by today's accelerated computing platforms. These challenges call for a fundamental architectural shift.

800 VDC power distribution provides:

• Higher efficiency by reducing resistive losses and copper usage
• Scalable infrastructure to deliver MW-scale rack power with highly compact solutions
• Global alignment with the IEC's low-voltage DC (LVDC) classification (≤1,500 VDC)
• Simplified power distribution with efficient thermal management
  
  
  
   

The 800 VDC architecture enables direct conversion from 13.8 kVAC utility power to 800 VDC within the data center power room or perimeter. By leveraging solid-state transformers (SSTs) and industrial-grade rectifiers, this approach eliminates multiple traditional AC/DC and DC/DC conversion stages, maximizing energy efficiency, reducing losses, and improving overall system reliability.

The 800 VDC distribution directly powers IT racks, eliminating the need for additional AC-DC conversion stages, and is stepped down through two high-efficiency DC-DC stages (800 VDC to 54 V/12 VDC, and then to point-of-load GPU voltages), to drive advanced infrastructure such as the NVIDIA Rubin Ultra platform.

These state-of-the-art AI factories demand unprecedented levels of power density, efficiency, and scalability, which can be enabled by Navitas' high-performance GaNFast and GeneSiC technologies.
