  • Common mode signal reduction in powerline communication devices
    Patent number: 9001926
    Abstract: An active common mode current limiting mechanism limits common mode currents in a powerline communication device. A powerline coupler determines a common mode signal component of an output signal of the powerline communication device. The powerline coupler provides voltage estimates of the common mode signal component to a signal processing unit. The signal processing unit generates samples of the voltage estimates of the common mode signal component. The signal processing unit adjusts transmit voltage levels of the powerline communication device based on the samples of the voltage estimates of the common mode signal component to limit the common mode signal component of the output signal.
