Abstract
An efficient, modular, direct current (DC) uninterruptible power supply (UPS) for at least one server of a data center is disclosed. The single-conversion DC UPS includes an AC-DC converter, an energy storage device electrically coupled to the output of the AC-DC converter, and a single conversion server supply DC-DC converter electrically coupled to the AC-DC converter and the energy storage device, which may be a low-voltage lithium-ion battery or combined with an ultra capacitor. The DC UPS may be incorporated into a UPS system for a data center including a plurality of server rack assemblies and a plurality of cooling distribution units (CDUs). The UPS system includes an electric generator, an AC UPS electrically coupled between the electric generator and the plurality of CDUs, and a plurality of DC UPSs coupled between the electric generator and the plurality of server rack assemblies.
