Abstract
Power line communication (PLC) systems are presented for connecting dimming switches with electronic ballasts for driving compact fluorescent lamps and other applications using a power distribution network, including a transmitter and a receiver connected in a series circuit for transmission of multi-bit data, where the receiver has a load control circuit for selectively adjusting the receiver loading and to sense current interruptions to provide a data output.
