Data transfer of a control system with using power line communication

A brushless DC fan motor control system that is powered and controlled through only one wire is presented in this paper. The DC-BUS power line multiplex technology transfers digital information to controller over a single cable that conducts both power and communication. The technology simplifies the installation, reduces harness weight and supports 16 devices operating at 10 kbps rate. A prototype power line communication system based on DC-BUS power line multiplex technology is designed and tested with using 56F8013 DSC from Freescale Semiconductor 56F8000 digital signal controller family. Keywords: Power Line Communication (PLC), DC-BUS, Broadband over Power Line (BPL), Digital Signal Controller (DSC 56F8000).
