Abstract
This application discloses a non-current equalization UPS apparatus, a current distribution method, and a parallel UPS system. The current distribution method may be applied to any UPS apparatus in a parallel UPS system. A current proportion of a first current output by the any UPS apparatus in a total output current of the parallel UPS system is positively related to a capacity proportion of an available battery capacity of a battery string correspondingly connected to the any UPS apparatus in a total available battery capacity of the parallel UPS system. Therefore, a system backup time of the parallel UPS system can be prolonged, and resource utilization of a battery string with a large available battery capacity can be improved.
