Modeling of a communication channel on a PWM electrical network

International audienceThis paper deals with the transfer of data byPower-Line Communication (PLC) on a Pulse Width Modulated(PWM) energy network. Target applications concern theadjustable speed drive for industrial application. In order toimplement an efficient communication solution, it is necessary tohave a model of the communication channel to determine certainparameters like bandwidth or the modulation formats. Theoriginality of our works is the methodology used to determine thechannel model. The first results of simulation and experimentalvalidation are presented in this paper
