Core Insights - The white paper on 800V DC power supply technology for data centers highlights the shift towards higher power density, with single cabinet power increasing from 6kW to 600kW or more, revealing the limitations of traditional AC power systems in terms of efficiency and space utilization [1][3]. Group 1: Technology Overview - The 800V DC power supply system is identified as a key direction for energy architecture innovation in data centers, addressing the inefficiencies of traditional AC systems and low-voltage DC systems [1][2]. - The system features three main technical routes, with the solid-state transformer (SST) converting AC 10kV directly to DC 800V being the optimal choice due to fewer conversion stages and higher efficiency [2]. Group 2: System Advantages - The 800V DC system supports the integration of distributed renewable energy sources like solar and storage, enabling a unified "source-grid-load-storage" construction [2]. - It enhances the synergy between computing and electricity, achieving efficient matching of computing power and electrical power through rapid power adjustment and reduced conversion losses [2]. - The system's efficiency is improved by over 3%, with a footprint reduced to less than 50% of traditional UPS systems, significantly decreasing copper usage and shortening construction time [2]. Group 3: Key Components - The SST, utilizing third-generation semiconductor materials (SiC), achieves efficient voltage conversion and stable control, with an average fault-free operation time of approximately 11 years [2]. - The system is designed to be compatible with various loads, achieving a DC800V to DC48V conversion efficiency of 98.5%, and is naturally compatible with distributed photovoltaic storage systems [2]. Group 4: Market Trends - Major companies like Meta, Microsoft, and NVIDIA are actively investing in 800V DC power supply technology, planning to implement it gradually from 2026 to 2027 [3]. - As computing power demands continue to rise, the voltage levels for board-level chip power supplies are expected to upgrade to DC800V or ±DC400V, with SST flexible DC power supply systems becoming mainstream [3]. - The transition to higher voltage levels in DC power supply technology is anticipated to drive the evolution of data center power systems towards greater efficiency, sustainability, and intelligence [3].
