Abstract
An embodiment of the present invention provides a load sharing control device included in each of multiple power supply devices connected to a load in parallel, the load sharing control device comprising: a first control unit for generating a first control signal which controls an output current of a power supply device, by using the output current of the power supply device and a current of a load share bus; and a second control unit for generating a second control signal which controls an output voltage of the power supply device, by using a target voltage of the power supply device, a feedback voltage received as feedback from the output voltage of the power supply device, and a control voltage according to the first control signal of the first control unit, wherein the first control unit generates the first control signal so that the output current is identical to the current of the load share bus, and limits the output current to a threshold current or less.
