Impedance Matching Circuit Design and Optimisation for Broadband Power Line Communications

摘要

This paper presents a numerical optimisation approach to an impedance matching circuit design for broadband power line communications. The proposed numerical optimisation method can be used to design any impedance matching circuit topology with the optimal circuit parameters for a broadband power line modem to match its power line connection point impedance measurements. The method has been tested based on filed measurements from one field substations of EdF in France. The enhancement of the gain performances is finally discussed.
