1. A control apparatus, comprising:
a control unit configured to;
control a power system that comprises:
a power supply connected to a load via a power supply line;
a capacitor configured to assist the power supply, wherein
the capacitor is connected to the power supply line via a first switch,
the capacitor is configured to be charged based on current limitation due to an intermittent driving operation by a switching power supply, and
the switching power supply is configured to use the power supply as input; and
a second switch between the switching power supply and the capacitor;
control an output voltage of the switching power supply to become equal to a voltage of the power supply line;
control the first switch from an off-state of the first switch to an on-state of the first switch after completion of a charging operation of the capacitor;
control the second switch from an off-state of the second switch to an on-state of the second switch based on start of the charging operation of the capacitor;
control the second switch from the on-state of the second switch to the off-state of the second switch based on the completion of the charging operation of the capacitor; and
based on the completion of the charging operation of the capacitor, control output of the switching power supply from an on-state to an off-state after the second switch is controlled from the on-state of the second switch to the off-state of the second switch.
