In this paper, a communication system that is not using the communication line but power line is presented. It will be very useful for an information-oriented society with tele-metering and home automation. Conventional system has a difficulty in transmitting information due to decreasing communication voltage and increasing carrier current. Proposed idea is a special type switching amplifier system which has a low inner resistance. It can provide reactive power and does not have low impedance between the transceivers. This new system is proposed to overcome the loss of conductor load in a PLC system.
