Envision puts 800-volt power system into operation at China AI campus
Envision has put an 800-volt power system into commercial use at an AI facility in Inner Mongolia, China.
The system is at the Galaxy AI campus in Ulanqab and converts electricity from the grid directly into an 800-volt direct-current supply.
The design uses fewer conversion steps, which Envision says could improve efficiency, save space and reduce cabling needs.
Batteries are meant to respond quickly when AI processors draw more power and provide short-term backup during interruptions.
Independent figures have not confirmed the claimed benefits, and performance under sustained full load has not been established.
Envision plans to use the technology in a wider initiative targeting 5 gigawatts of renewable-powered computing capacity by 2030.
Envision says it has put an 800-volt direct-current power system into commercial operation at an AI facility in Inner Mongolia.
The system is at the Galaxy AI campus in Ulanqab and converts 10-kilovolt alternating current directly into an 800-volt direct-current supply.
It combines a solid-state transformer, battery storage and a controller designed to respond to changes in processor demand.
Envision says the design can improve efficiency and reduce the space and cabling required, but independent performance figures have not been disclosed.
The Galaxy facility is expected to grow to 3 gigawatts and could eventually serve one million AI accelerators, according to the company.
