Abstract
A load sharing device for load balancing among a plurality of power supply modules connected in parallel to a single load includes a common voltage control signal output unit and output voltage control units corresponding to the power supply modules, respectively. The common voltage control signal output unit generates a common voltage control signal from output voltages of the power supply modules and outputs the common voltage control signal to the power supply modules. The output voltage control units detect output currents of the power supply modules and control the output voltages of the power supply modules to be in a predetermined voltage range according to the common voltage control signal and the detected output currents.
