Abstract
A signal coupling apparatus for power line communications includes an impedance matching transformer and a transmission mode control circuit for high data rate power line communications on a three-phase four-wire distribution line. Therefore, it is possible to improve the efficiency of power line communications, to minimize signal loss, and to construct an optimal high voltage distribution path.
