PROBLEM TO BE SOLVED: To provide a power source supply control system capable of preventing current from reversely flowing to each of a plurality of power source supply sources connected to a load.SOLUTION: A power source supply control system comprises: a load; a plurality of power source supply sources; a switch unit for switching connection between the load and each of the plurality of power source supply sources by using a plurality of switch circuits. Each of the plurality of switch circuits compares first voltage obtained by decreasing, by a first voltage level predetermined for each switch circuit, output voltage of a power source supply source to be connected with second voltage obtained by decreasing, by a predetermined second voltage level, voltage of a connection point with the load; and cuts off electric connection between the power source supply source and the load when the second voltage is equal to or higher than the first voltage and electrically connects the power source supply source with the load when the second voltage is lower than the first voltage. |
