1. A converter device comprising:
a power conversion circuit including a reactor and at least one switching element, the power conversion circuit converting a voltage of alternating-current power supplied from an alternating-current power supply into a direct-current voltage, and outputting the direct-current voltage;
a current detector detecting a current flowing in the reactor or the switching element;
a filter circuit filtering a first signal detected by the current detector; and
a control unit generating a control signal on a basis of a carrier and a second signal generated by the filter circuit and controlling, on a basis of the control signal and with a first period, the switching element, the first period being a period of the carrier, wherein the filter circuit cuts off a repetition frequency component in the first period and passes a repetition frequency component in a second period, the second period being longer than the first period, wherein the current detector detects the current with the second period.
