Abstract: A communication system and method of operating the same that includes, in one embodiment, a transmit filter including a transmit filter capacitor, and a receive filter coupled to the transmit filter. The communication system also includes a switch, coupled to an auxiliary winding of a transformer and to the transmit filter capacitor, configured to alter an impedance of the transmit filter during a receive mode of operation of the communication system. In another embodiment, a transmitter is configured to receive an input data stream, and produce a control signal for a switch-mode power amplifier employing a predetermined data sequence selected by the input data stream thereto.

Abstract: An electric system, method, and computer-readable medium facilitate shared access to a shared power line for communication using a PLC protocol. The electric system, method, and computer-readable medium may determine when the shared power line is available for a transmission, allocate unicast transmission time slots to each of a plurality of inverters, transmit a multicast message requesting that each of the plurality of inverters communicate information during its allocates transmission time slot, determine whether a first inverter in the plurality of inverters did not communicate using the shared power line during its allocated unicast transmission time slot, and if the first inverter did not communicate information during its allocated unicast transmission time slot, transmit with the line interface a jam signal during the first inverter's unicast transmission time slot.
