[Vision: The world's first 800V SST high-voltage DC system realizes commercial operation of AI data centers] On November 2, Envision Technology Group announced on November 2 that its integrated 800V high-voltage DC power supply system has been put into commercial operation at the Ulanqab Galaxy Base, becoming the world's first system of its kind to be commercially operated in a large-scale AI data center. The system consists of Tianshu controller, solid-state transformer (SST), DC energy storage and DC/DC. Envision’s Ulanqab Galaxy Base was put into operation in August this year, with a planned capacity of 3GW, and the proportion of green electricity direct connection will exceed 80%. Huang Zhiyong, senior vice president of Envision Energy, said that the AI ​​data center requires an AIDC power system that can coordinate renewable energy, energy storage, grid dispatch and computing load. This commercial operation marks that the Envision AIDC power system has completed a complete closed loop from green power production to computing load.
