Evolution of Power Supply Tech in Intelligent Computing Centers

The document discusses the transformation and evolution of power supply technology in intelligent computing centers, driven by the exponential growth of AI and computing power demands. It outlines the core modules of data center power systems: power transformation and distribution, self-provided generators, uninterruptible power supplies (UPS), and backup batteries. The architecture evolves from centralized AC UPS to high-voltage DC (HVDC) and distributed designs to improve efficiency and reliability. Power supply equipment includes transformation and distribution gear, primary UPS (AC or HVDC), and secondary server power supplies. The rise of AI clusters (from 10,000 to 100,000 GPUs) leads to high power consumption, with single cabinets reaching MW levels by 2028. Challenges include load surges (up to 320% in 10ms), high power density, and voltage upgrades to 240V/336V DC. The document emphasizes the need for advanced power solutions like solid-state transformers and Panamanian power supplies to meet future energy demands.
