1. A system for transmitting control signals to internal devices of a compressor, wherein the compressor includes a housing, a sealed power terminal, and a motor for powering the compressor, the system comprising:

  • a first signal converter disposed externally of the compressor housing, the first signal converter being configured to receive a control signal and convert the control signal to a modulated signal;

    a second signal converter disposed internally of the compressor housing, the second signal converter being configured to decode the modulated signal;

    a plurality of power transmission lines connected to an AC input power source, the plurality of power transmission lines also connected to the sealed power terminal;

    wherein the first signal converter is electrically coupled to at least one power transmission line of the plurality of transmission lines to transmit the modulated signal to the second signal converter, and the second signal converter is coupled to the at least one power transmission line and configured to receive the modulated signal and to generate a driver signal in response to the modulated signal for operating at least one of the internal devices of the compressor.
