Abstract

Aiming to introduce new directions to improve the performance of narrow-band power line communication (PLC) systems in low-voltage electric power grids, this study introduces an active-based capacitive PLC coupling circuit for duplex communication. Simulations show that transmission and reflection parameters achieved good results while the Op-Amp provide a desired signal gain in the pass-band.
