Abstract (en)

[origin: WO2018069424A1] The invention relates to a communication system in a current supply grid, having at least one controller and at least one current conversion device. The current supply grid is simultaneously used for communication between the at least one current conversion device and the controller. The voltage is modulated for the communication between the at least one power conversion device and the controller, wherein the modulated current signal is superimposed over a current to/from the current conversion device, and the modulation is implemented by a device selected from the group having a power factor correction device and an inverter.
