NVIDIA Selects Navitas to Collaborate on Next Generation 800 V HVDC Architecture

Core Viewpoint - Navitas Semiconductor's GaN and SiC technologies have been selected to support NVIDIA's next-generation 800 V HVDC data center power infrastructure, which is designed to enhance power delivery for AI workloads and support 1 MW IT racks and beyond [1][15]. Group 1: Technology Collaboration - The collaboration between Navitas and NVIDIA focuses on the 800 V HVDC architecture, which aims to provide high-efficiency and scalable power delivery for AI workloads, improving reliability and reducing infrastructure complexity [2][4]. - Navitas' GaNFast™ and GeneSiC™ technologies will enable the powering of NVIDIA's GPUs, such as the Rubin Ultra, directly from the 800 V HVDC system [1][6]. Group 2: Advantages of 800 V HVDC - The existing data center architecture, which uses traditional 54 V in-rack power distribution, is limited to a few hundred kilowatts and faces physical limitations as power demand increases [3]. - The 800 V HVDC system allows for a reduction in copper wire thickness by up to 45%, significantly decreasing the amount of copper needed to power a 1 MW rack, which is crucial for meeting the gigawatt power demands of modern AI data centers [5][6]. - This architecture eliminates the need for additional AC-DC converters, directly powering IT racks and enhancing overall system efficiency [6][13]. Group 3: Performance and Efficiency - NVIDIA's 800 V HVDC architecture is expected to improve end-to-end power efficiency by up to 5%, reduce maintenance costs by 70% due to fewer power supply unit (PSU) failures, and lower cooling costs by connecting HVDC directly to IT and compute racks [13]. - Navitas has introduced several high-efficiency power supply units (PSUs), including a 12 kW PSU that meets 98% efficiency, showcasing the company's commitment to innovation in power delivery for AI data centers [12]. Group 4: Company Background - Navitas Semiconductor, founded in 2014, specializes in next-generation power semiconductors, focusing on GaN and SiC technologies for various markets, including AI data centers and electric vehicles [17]. - The company holds over 300 patents and is recognized for its commitment to sustainability, being the first semiconductor company to achieve CarbonNeutral® certification [17].
