POWER LINE COMMUNICATION CONTROL SYSTEM

摘要

A power line communication control system for coupling between an power line and a load is disclosed. The exemplary system is capable of simultaneously distributing electrical power and transmitting communication signals with minimized interference there-between. The exemplary system includes an inductive coupling input terminal and an inductive coupling output terminal. Each of the input and the output terminals includes a pair of series-connected inductors having substantially identical inductance value. Accordingly, the system is capable of may deliver the household power signal under common mode transmission while transmitting the communication signal using differential mode transmission, thereby minimizing the interference between the power line AC current and the communication signal.
