An operation mode selection unit selects an efficiency priority mode for minimizing the overall loss in a power supply system based on a load request voltage obtained in accordance with the condition of a load and on the conditions of DC power supplies, and generates a mode selection signal in accordance with the selection result. When SOC and/or output power have/has reached power supply restriction values in any DC power supply, an operation mode modification unit generates a final mode selection instructing signal so as to modify selection of the efficiency priority mode by the mode selection signal to select an operation mode in which power distribution between the DC power supplies can be controlled.
