System for transmitting and receiving a power line communication signal over the power bus of a power electronic converter
First Claim
1. A system for transmitting and/or receiving a communication signal via a power conductor of a power electronic converter with a plurality of converter modules, wherein the communication signal comprises control signals, including gate signals, and sensing signals between a main controller and a local controller of the power electronic converter, wherein the main controller sends the control signals to the local controller, and wherein the main controller receives the sensing signals from the local controller, the system comprising:
- a transceiver adapted to modulate the communication signal on a communication signal frequency hand, anda coupler connected to the power conductor and adapted to couple the modulated communication signal to or from the power conductor of the power electronic converter, thereby exchanging said control and sensing signals between said main and local controllers of the power electronic converter.
