Abstract: A transmitter device is provided for transmission of data via DC power distribution lines includes a sequence generator arranged for receiving a raw data bit stream to be transmitted over a positive and a negative DC power distribution line and for deriving a switching sequence based on the raw data bit stream, and a circuit including one or more capacitors and a plurality of switches controllable with the switching sequence derived in the sequence generator.

Abstract: A transmitter device for transmission of data via DC power distribution lines includes a sequence generator arranged for receiving a raw data bit stream to be transmitted over a positive and a negative DC power distribution line and for deriving a switching sequence based on the raw data bit stream, and a circuit including one or more capacitors and a plurality of switches controllable with the switching sequence derived in the sequence generator. The circuit is arranged for injecting in the positive and negative DC power distribution lines symmetric displacement currents resulting from displacing charges on the one or more capacitors when the one or more capacitors are charged or discharged according to the switching sequence. The symmetric displacement currents give rise to changes in voltage of the same magnitude and opposite polarity on the positive and negative DC power distribution lines.
