SYSTEM FOR TRANSMITTING AND RECEIVING A POWER LINE COMMUNICATION SIGNAL OVER THE POWER BUS OF A POWER ELECTRONIC CONVERTER

摘要

The present invention is concerned with a system for transmitting and/or receiving the control and sensing signals between the control units and the power electronic components. The system according to the present invention comprises: a transceiver (21, 31) adapted to modulate the communication signal on a communication signal frequency band, and a coupler (20) connected to the power conductor (130) and adapted to couple the modulated communication signal to the power conductor. The present invention also concerns a method for transmitting and receiving the control and sensing signals.
