57	Abstract	AB	A control circuit 11 of the present invention controls the discharge of an X capacitor C100 connected between power supply lines AC1, AC2 of an AC-DC converter 51, the power supply lines being lines of alternating current of opposite polarities, and the AC-DC converter being a converter to which alternating current is inputted and which converts the alternating current into direct current and outputs the direct current. The control circuit 11 detects a change state of the voltage across the X capacitor C100 and controls the discharge so as to discharge the charge accumulated in the X capacitor C100 on the basis of the change state.　This control circuit 11 makes it possible to reliably discharge the charge accumulated in the X capacitor C100 even if the alternating-current input voltage fluctuates significantly.
