UNINTERRUPTIPLE POWER SUPPLY SYSTEMS AND METHODS SUPPORTING LOAD BALANCING

摘要

An uninterruptible power supply (UPS) system that includes a multiphase AC output configured to be coupled to a load, an inverter having an output coupled to the AC output and a control circuit operatively associated with the inverter and configured to cause the inverter to compensate for a phase imbalance of a load coupled to the AC output while power is being delivered to the load from an AC power source independently of the inverter.
