SYSTEM AND METHOD FOR IMPROVED DC POWER LINE COMMUNICATION

A device for communicating over a DC power line cable having at least two conductors is described. The device comprises a first inductor having two secondary windings and one primary winding. The device further comprises a first transceiver coupled to the primary winding of the first inductor. The two secondary windings of the first inductor are coupled on a first end to two of the at least two conductors of the DC power line cable and on a second end to a DC power supply. The second end of one of the two secondary windings of the first inductor is coupled to a DC voltage supply and the second end of the other of the two secondary windings is coupled to a DC power supply return to provide power to the DC power line cable. The primary and secondary windings of the first inductor are magnetically coupled to enable magnetically coupled communication between the first transceiver and the two of the at least two conductors in the DC power line cable.
