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 filterstoare configured to reduce distortion of a load current supplied from the AC power supplyto the load device, based on a detection signal output from the load current sensor, the detection signal relating to the distortion of the load current; and the signal transmitting unitconfigured to cause the plurality of active filterstoto 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 filtersto, based on the detection signal output from the load current sensor
