Designing Coupling Circuits for Communication of High-Frequency Signals Over Power Lines

摘要

There are areas where the digital communication may be made through low-voltage distribution network. This helps the utilities to reach at remote locations. Mapping of the consumer through control center is achieved through interfacing of coupling circuits that leads to distribution load management. This paper presents designing of broadband coupling circuit that satisfies specific signal transmission, appropriate bandwidth, and limited number of components. The paper also discusses the significant parameter variations during capacitive couplings and inductive couplings for passive and active network topologies.
