A power supply module current sharing method and system manager

The present invention discloses a method of power flow of each module, and the system manager, the power module is in the field. Method: first output current ratio of the first and second power supply module PSU PSU group manager determines in parallel, and each PSU to obtain a first output current ratio of each of the first adjustment and second PSU PSU group after the PSU output current of the first group and the second group, all PSU PSU and power supply system of the first sum and the power loss; PSU a first group comprising one or more parallel and powered by a PSU HVDC system, a second group consisting of PSU AC system; determining a current ratio according to a first output of the second output current ratio, power loss and obtaining a second sum; and comparing the first sum and the second power loss of power loss and, according to the comparison result and a second output current determining a third ratio of the output current ratio; the third output current sent to the first ratio and the second set of PSU PSU group PSU, so that the first and the second set of PSU PSU PSU third set of outputs according to the output current ratio adjustment current.
