Power line communication for lighting applications using binary phase shift keying (BPSK) with a single DSP controller

DSP controllers provide the on-chip peripherals and computational power needed to implement various power electronics applications. A single-chip DSP controller allows designers to implement multiple functions such as power line communication, power-factor correction, and inverter control, all needed for an overall dimmable lighting ballast application. This paper presents a complete implementation of a power line modem following CEA-709 protocol using a single DSP. The paper also shows how to utilize the remaining on-chip peripherals and computing cycles to implement inverter control suitable for lighting and other inverter operations.
