Core Viewpoint - Nvidia is redefining the characteristics and functionalities of power electronic devices for AI data centers, despite not designing or manufacturing power devices itself [2][9]. Group 1: Nvidia's Influence on Power Electronics - Nvidia's push for AI data centers is creating momentum for Gallium Nitride (GaN) technology, similar to how Silicon Carbide (SiC) benefited from Tesla's early adoption [6]. - Nvidia is collaborating with various partners, including Infineon, MPS, Navitas, and others, to transition to an 800V High Voltage Direct Current (HVDC) power infrastructure for data centers [3][10]. - The company is moving away from traditional 54V rack power distribution technology due to its inability to meet the increasing power demands of large GPU clusters [8][9]. Group 2: Technical Requirements and Innovations - The new 800V HVDC architecture will necessitate a range of new power devices and semiconductors, with a focus on converting 800V to lower voltages for server motherboards [10]. - Infineon indicates that SiC is leading in high power and voltage solutions, while GaN is more suited for high-frequency applications due to space constraints [11]. - New semiconductor-based relays will be required for the high voltage DC AI data centers to ensure safe control of overcurrent and surge currents [12]. Group 3: Competitive Landscape and Market Dynamics - Nvidia's proactive approach in announcing its power infrastructure plans is driving industry dialogue and may render existing standards like the Open Compute Project (OCP) obsolete [16]. - The market for GaN is expected to grow faster than SiC, with GaN devices having higher voltage potential and applications in both DC/DC and AC/DC conversions [19].
