Power munication for Lighting Applications
Using Binary Phase Shift Keying (BPSK) with a Single
DSP Controller
.............................................................................................................. C2000 - Systems Application
ABSTRACT
DSP controllers provide the on-chip peripherals putational power needed to
implement various power electronics applications. A single-chip DSP controller allows
designers to implement multiple functions such as power munication,
power-factor correction, and inverter control, all needed for an overall dimmable lighting
ballast application. This application report presents plete implementation of a
power line modem following CEA-709 protocol using a single DSP. This paper is a
shorter version of the detailed documentation of this implementation titled
TMS320C2000 Digital Signal Controller Power munication User's Guide
(SPRU714) which can be downloaded from http:.
