Disclosed is a power supply system (201) wherein: a plurality of units (100A, 100B and so on), each of which has a converter section (1) that performs power conversion, are provided; an input section and an output section of each of the units (100A, 100B and so on) are connected in parallel; the units (100A, 100B and so on) are communicating with each other; and the unit (100A) is set as a master module that controls driving and stopping of other units (100B and the like). The unit (100A) makes all other units (100B and the like) driven when an output current (Io) exceeds a threshold value, said output current having been detected by means of an output current detection circuit (5). In the cases where all the units (100B and the like) are driven, one of the all other units (100B and the like) is stopped on the basis of the total of the output currents of the units (100A, 100B and so on). Consequently, provided is the power supply system capable of suppressing the modules being used in an overcurrent state when a load current is rapidly increased. |
