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.

Abstract: A power allocating apparatus has a plurality of power supply modules coupled to a plurality of loads via a plurality of power lines, respectively. The power allocating apparatus includes a first switch element and a control device. The first switch element has a first connecting terminal and a second connecting terminal coupled to an output terminal of a power supply module with a relatively high power conversion rate and an output terminal of a power supply module with a second power conversion rate, respectively, and selectively allocates a power generated by the power supply module with the relatively high power conversion rate to a predetermined number of loadings simultaneously according to on or off states of the first switch element. The control device is coupled to the first switch element to control the first switch element to enter an on state or an off state.
