  • System and method for detecting and correcting DC bus imbalances between parallel coupled UPS systems sharing a common battery
    Patent number: 10454301
    Abstract: The present disclosure relates to method for use with a system having first and second uninterruptible power supplies (UPS 1 and UPS 2), and where the two UPSs are connected across a DC+ and a DC? terminal of a common battery, and where a neutral imbalance between neutral lines of the two UPSs has been corrected, giving rise to a current flow from a DC? bus of one of the UPSs to a DC? bus of the other one of the UPSs. The method corrects for a nominal DC reference voltage for one of the UPSs to eliminate the current flow to the DC? bus of the other UPS.

  • Method of controlling an uninterruptible power supply to clear a shorted load
    Patent number: 9825489
    Abstract: An uninterruptible power supply system has a three-level T-Type inverter A method that improves clearing a short of a load coupled to an output of the inverter when the load experiences a short circuit event includes commutating with a controller each phase of the inverter in a two level mode current generation when output voltage and output current of that phase have the same direction and commutating each phase of the inverter in a three level mode current generation when the output voltage and output current of that phase have opposite directions.
