Abstract

The present invention relates to a transmitter device (10) for transmission of data via DC power distribution lines. The transmitter device comprises : - a sequence generator (12) arranged for receiving a raw data bit stream to be transmitted over a positive and a negative DC power distribution line (5a,5b) and for deriving a switching sequence based on the raw data bit stream, - a circuit comprising one or more capacitors (C1,C2) and a plurality of switches (S1,S2,S3,S4) controllable with said switching sequence derived in said sequence generator, said one or more capacitors being connectable to the positive and negative DC power distribution lines via the plurality of switches, wherein said 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 sequence of switching, said symmetric displacement currents giving rise to changes in voltage of a same magnitude and opposite polarity on the positive and negative DC power distribution lines, said voltage having a same frequency as the raw data bit stream.
