Abstract
Active droop current sharing among power supply units may regulate output currents of power supply units supplying shared current to a common load. The regulation may employ a combination of droop control and active current control. The shared current may be regulated such that each power supply unit provides a substantially equal share of the total current supplied. A current difference between two power supplies may be regulated to be within a desired maximum threshold for current difference.
