A Study on the Power Line Control System for Electric Machinery using Power Line Communication

전력선 반송통신을 이용한 전기기기 전원 제어 시스템에 관한 연구

Recently, a study on the Power Line Communication has been done by many companies and institutes due to its own merits that we can use the power line as a communication channel. But, there are serious problems about the harsh and unpredictable characteristics - noise, signal distortion and attenuation to be overcome in order that we commercialize the Power Line Communication. In this paper, we analyse the power line characteristics and apply the technology of PLC to control power of electric machinery by using ASK modulation.
