Abstract
An output circuit sends a control pilot signal generated in a voltage generator to an input circuit. A communication unit is connected between an earthed wire and a control pilot wire on the output side of the output circuit via a bandpass filter. A communication unit is connected between the earthed wire and the control pilot wire on the input side of the input circuit via a bandpass filter. A low-pass filter is interposed between the output circuit and the communication unit. A low-pass filter is interposed between the input circuit and the communication unit.
