A harmonic-suppressing device 100 suppresses a harmonic current generated by a device 10 connected to an alternating-current power source 1 via a wiring part 200, wherein the harmonic-suppressing device 100 has: a device current detection part 102 for detecting, from among the currents flowing through the wiring part 200, a device current Idev that includes a harmonic component; a plurality of harmonic-suppressing parts 120 for suppressing the harmonic component included in the device current Idev; and a control unit 110 for controlling each of the plurality of harmonic-suppressing parts 120 using the device current Idev detected by the device current detection part 102. |
