Abstract
A power supply system for a data center includes an isolated AC-to-DC power conversion unit, an isolated DC-to-DC power conversion unit, an energy storage unit, a first DC bus and a second DC bus. The input terminal of the power supply system is connected with an AC power source. By the isolated DC-to-DC power conversion unit, a first DC voltage from the first DC bus is converted into a second DC voltage. The second DC voltage is provided to the second DC bus. The main power circuit in the isolated DC-to-DC power conversion unit is an LLC circuit or a boost-SRC circuit. The second DC voltage is between 0.5V and 60V. The energy storage unit is electrically connected with the first DC bus. When the isolated AC-to-DC power conversion unit works normally, the energy storage unit is charged to a floating charge state.
