Abstract
A technology that can reduce the influence of variations in the reference potential of each current output device on the operation of multiple current output devices, when using the multiple current output devices to reduce the distortion of the load current, is provided. A plurality of active filters 41 to 43 are configured to reduce distortion of a load current supplied from the AC power supply 10 to the load device 20, based on a detection signal output from the load current sensor 30, the detection signal relating to the distortion of the load current; and the signal transmitting unit 44 configured to cause the plurality of active filters 41 to 43 to acquire a signal relating to the distortion of the load current, to reduce influence due to variation of a standard potential of the plurality of active filters 41 to 43, based on the detection signal output from the load current sensor 30.
