Power Supply Revolution in Edge Computing
Traditional edge nodes are limited by space and power supply, making it impossible to support high-power devices. The high-voltage direct current characteristics of 800V HVDC can directly power micro data centers, and combined with the miniaturization advantages of GaN devices, it makes kilowatt-level computing power deployment in streetlights and base stations possible. NVIDIA predicts that after 2028, edge AI cabinets will popularize 800V direct supply to support real-time decision-making for autonomous driving.

Energy Foundation for Quantum Computing
Quantum computers require extremely low temperatures and stable power, with current energy consumption reaching megawatt levels. The low loss and fast response characteristics of 800V HVDC can meet the millisecond-level power fluctuation requirements of quantum devices. Google and IBM have already experimented with using HVDC for quantum cooling systems, achieving a 40% efficiency improvement. In the future, “quantum-AI hybrid clusters” may rely on the 800V architecture to achieve energy synergy.

Challenges of Technological Integration
The combination of 800V HVDC with optical interconnects and superconducting technology is still in its early stages. For example, solid-state transformers (SST) need to be compatible with photonic transmission protocols; otherwise, signal conversion efficiency will be limited. Additionally, grid-level HVDC must address quantum encryption security requirements, and existing power protocols face reconstruction.800V HVDC is a bridge connecting AI and next-generation computing.Companies should proactively layout cross-technology research and development; otherwise, they may miss the entry dividend of the edge and quantum era.
