A Chinese company has introduced an advanced technology to supply data centers with 800-volt direct current power in its first commercial application. The system was installed at the Galaxy AI complex in the city of Ordos, Inner Mongolia, with the
technology announced on November 2. Data centers typically receive alternating current from the power grid, while servers require direct current, necessitating multiple conversions using additional equipment. This system’s solid-state transformers convert 10 kilovolts directly to 800 volts DC. High voltage
allows the same power to be transmitted with lower current, reducing the number of cables and devices and freeing up space for servers. Batteries stabilize voltage fluctuations, and the Dubhe Controller AI system adjusts power supply according to equipment needs.
The Galaxy AI complex began operations in August 2026 and is planned to expand to 3 gigawatts capacity, accommodating up to one million AI accelerators that perform complex computations for training and running neural networks. The company anticipates that over
80% of the complex’s electricity will come from renewable sources in the future and is developing the Mission Gobi project to build renewable-powered data centers with a total capacity of 5 gigawatts in desert regions worldwide by 2030. Kevin Huang,
the company’s vice president, described this technology as an important step from concept to practical application.
