A DC-DC converter control apparatus controls a DC-DC converter which has an inductor connected between an input terminal for a direct-current input voltage and an output terminal for a direct-current output voltage obtained by converting the direct-current input voltage, a capacitor connected to the inductor, and a switch configured to switch whether the direct-current input voltage is applied to the inductor. The DC-DC converter control apparatus has a subtractor configured to generate a differential voltage between the direct-current input voltage and a reference voltage, a comparator configured to generate a determining signal that indicates determination of a polarity of the differential voltage, and a delay part configured to delay the determining signal for a specific delay time.
