Abstract
A power supply control apparatus is applied to a power supply system that includes an opening and closing unit that has a plurality of switches that are connected in series on an energization path over which energization from a voltage source is performed and a plurality of diodes that are respectively connected in parallel to the plurality of switches, in which the plurality of diodes include diodes that are arranged in opposite directions to each other. The power supply control apparatus includes a determining unit determining that an abnormal state has occurred in which a current is flowing to any of the plurality of diodes in a state in which the plurality of switches are turned off, and a control unit controlling the switch that is connected in parallel to the diode through which the current is flowing to an on-state, when the abnormal state is determined to have occurred.
