Title: CURRENT EQUALIZING DEVICE, METHOD AND SYSTEM
Abstract:
A current equalizing device, method and system. The current equalizing device (702) comprises: a monitor (101) and at least two processors (102), wherein the at least two processors (102) and at least two external power supplies (701) connected in parallel to each other are connected in one-to-one correspondence; the monitor (101) acquires the current output current of each power supply (701), calculates an average current according to the current output current of each power supply (701), and sends the average current to each processor (102); and each processor (102) determines whether the current difference between the current output current of the correspondingly connected power supply (701) and the average current sent by the monitor (101) exceeds a pre-set difference interval, and if so, the correspondingly connected power supply (701) is controlled so that same adjusts an output voltage. In the technical solution, the output voltage of a power supply is adjusted according to the difference between the current output current of the power supply and the average current obtained by means of calculation, so as to realize the adjustment of the output current by means of adjusting the output voltage of the power supply, thereby improving the uniformity of current output.
