Swing Aboard the 800-V Bus: NVIDIA’s AI Power Architecture and the Chips to Drive It

Semiconductor makers are rapidly embracing NVIDIA's 800-V DC power architecture for AI factory computing platforms, aiming to support megawatt-level power consumption efficiently. The new architecture eliminates multiple conversion stages, offering improved efficiency, reduced cooling loads, and lower costs. Major semiconductor manufacturers and power-system component makers are already on board to support this transition. White papers from companies like EPC, Navitas Semiconductor, Power Integrations, Renesas, and ROHM Semiconductor delve into the practical aspects of designing and supporting AI data center power systems under this new architecture.
