Abstract
Power Line Carrier - PLC communication equipments where used by electricity companies to send data over high voltage power lines for almost thirty years. Recent developments in modulation and error correction algorithms made possible data rates of several mega bits per second, allowing this method to be used as an alternative for telephone and Internet home connection using the low voltage network. One of the most critical components of this transmission is the interface between the power line and the communication processor. Due to high voltages, impedance characteristics of power lines and, not at the last, due to extremely high amplitude and time-independent disturbances, the coupling network needs to be carefully designed to provide both the signal path and the safety required by the home-used equipment standards. Starting from standard configurations, this article presents some theoretical aspects of power line coupling network and propose a new protection circuit topology that complies with the most critical EMI condition documented in EN50065-1 and provides the largest available bandwidth for data transmission. |
