  • Controlling power to a load with signals along a power line
    Patent number: 10461809
    Abstract: A circuit, system and method for controlling electrical power to a load, the circuit has a controller with power supply input nodes and a controller data input node. Two power supply input terminals supply electrical power to the circuit. A digital control signal pre-processing unit couples one of the power supply input terminals to the controller data input node. The digital control signal pre-processing unit has a capacitor arranged to block voltage biasing resulting from power supplied across electrical power supply input terminals from being supplied to the controller data input node. The digital control signal pre-processing unit is arranged to generate positive and negative voltage impulses in response to corresponding rising and falling edges of a digital control signal provided at the power supply input terminals. The digital control signal pre-processing unit is further arranged to generate a revised version of the digital control signal without the voltage biasing.
