Torrance, California, May 21, 2025 (Globe Newswire) – Navitas Semiconductor (NASDAQ: NVTS), the industry leader in Ganfast ™ Gallium Nitrid (GAN) and Genesic ™ Silicon Carbide (SIC) semi -Semications, announced a collaboration with NVIDIA (NASDAQ: NVDA) on the next generation of HVDC architecture (NASDAQ: NVDA). Rubin Ultra, activated by Ganfast ™ and Genesic ™ Power Technologies.

The next generation of 800 V-DC architecture from NVIDIA aims to create a high level of efficiency and a scalable power supply for the next generation of AI work in order to ensure greater reliability, efficiency and a reduced complexity of the infrastructure.

Today’s existing data center architecture uses traditional 54 V-in-rack electricity distribution and is limited to a few hundred kilowatts (KW). Bewer copper bus bars are required to transfer this low voltage current from the shelves with the rack mounting into the calculation carrier. With increasing performance over 200 kW, this architecture increases due to performance density, copper requirements and reduced system efficiency to physical limits.

Modern AI calculation centers need gigawatts (GW) electricity for increasing demand for AI calculation. The approach of NVIDIA is to convert the 13.8 kV change of change power flow directly in 800 V HVDC at the Perimeter data center using solid-state and industrial wheel rectors, which eliminates several alternating current/DC and DC/DC conversion steps, which means that the efficiency and reliability are maximized.

Due to the higher voltage level of 800 V HVDC, the thickness of the copper wires can be reduced by up to 45%due to I²R losses, whereby the same performance can be delivered with increased voltage and lower electricity. With a conventional 54 V equal current system, over 200 kg copper would be required to supply a 1-MW rack with electricity, which is not sustainable for the next generation with GW power supplies.

The 800 V-HVDC operates the IT racks directly (eliminates the need for additional AC-DC converters) and is converted into lower tensions by DC DC converters that drive the GPUs like the Rubin Ultra.

Navitas is an established market leader in AI data center solutions that are made possible by GAN and SIC technology. The high-performance ICS Gansafe ™ Power ICS integrate functions for tax, drive, detection and critical protective features and enable unprecedented reliability and robustness. Gansafe is the world’s safest gan with short circulatory protection (350 NS maximum latency), 2KV ESD protection for all pens, elimination of the negative gate drive and programmable DLEW rate control. All of these characteristics are controlled with 4 pins so that the package can be treated like a discreet GAN-FET, whereby no V is required_CC Pen.

In addition, Navitas offers a family with a medium voltage (80-120 V) GAN devices that were optimized for the DC DC conversion of secondary pages and deliver high speed, high efficiency and small footprint for AI-offspring psus with expenses of 48 V-54 V.

Genesic Proprietary ‘Grench-Assisted Planar “technology enables 20 years of SIC innovation management, which offers leading performance over the temperature and delivers high-speed, cool operating operations for high-performance applications with high performance. 3x longer than SIC products from other providers.

SIC technology offers the broadest voltage area in the industry from 650 V to ultrahoh voltages from 2.3 kV to 6.5 kV and was implemented in several projects for MW energy storage and lattice-bound inverter with the Department of Energy (DOE).

Navitas Gan and SIC technologies cover the full power supply from GRID into the GPU.

In August 2023, Navitas introduced a high-speed CRP with a high eefficient with 3.2 kW and achieved a lower size of 40% than the best silicone solutions for the class for alloyed AI and EDGE computing. This was followed³And an efficiency of over 97%. In November 2024, Navitas released the world’s first 8.5 kW -KI calculation current that was operated by GAN and SIC and which could meet the efficiency of 98%, and comply with the specifications for the Open Compute Project (OCP) and Open Rack V3 (ORV3). In addition, Navitas Intelliweaven, an innovative patented new digital control technology, which in combination with high-performance goose-based and Gen-3-fast-SIC mosfets enables PFC efficiency increases to 99.3% and reduces electricity losses by 30% compared to existing solutions. In addition to the Computex exhibition in Taiwan, the recent publication of her 12 KW -PSU at the Navitas ‘Ai Tech Night’ was presented on the 21st^st May.

“We are proud to be selected by NVIDIA to work together on their 800 HVDC architecture initiative. Our latest innovations in high-performance high-performance gan and SIC technologies have seen Worlds and created new diffraction in markets such as AI data centers and electric vehicles,” said Gene Sheridan, CEO and Co-Fünder from Navitas. “With our wide portfolio area, we can support the 800 -V -V -HVDC infrastructure from grids from grid to the GPU. We appreciate that Nvidia recognizes our technology and commitment to the journey of the next generation of electricity supply of data centers.”

The 800 V-HVDC architecture of NVIDIA will improve the efficiency of the end-to-end performance by up to 5%, reduce the maintenance costs by 70% (due to fewer PSU failures) and reduce the cooling costs by connecting HVDC directly with the IT and calculation of racks.
