This document discloses a method of modifying modulation pattern of inverter semiconductor switches in such a way that communication between inverters can be achieved via power line. One inverter modifies its modulation from normal PWM, and this modification is recognized in another inverter by measuring the signal in the powerline. By beforehand determining what does certain distortion stands for, communication between inverters can be achieved.
