  • Patent number: 8035507
    Abstract: Stimulating power line carrier injection with reactive oscillation comprises exciting a tank circuit to oscillate at the carrier frequency by sinking pulses of current between one node of a capacitor in the tank circuit and the other node of the capacitor. A power transformer is connected to a distribution system to inject a power line carrier onto the power line. An excitation circuit sinks short pulses of current between one node of a capacitor and the other node of the capacitor that is connected in a tank circuit arrangement with an inductor and the secondary winding of the power transformer. The tank circuit oscillates at the frequency of the excitation pulses if the resonant frequency of the tank circuit is close to the frequency of excitation. The oscillating current is coupled onto the power line system through the power transformer. The phase of the power line carrier signal is shifted by shifting the phase of the excitation pulses.

  • Publication number: 20100289629
    Abstract: A load control device having two-way communication capabilities. The load control device can include a conventional load control receiver that receives information, such as load control commands or requests. The load control receiver can include a receiver operable to receive power line carrier signals via a power distribution line. The load control device can further include a power line carrier signal transmitter that couples a power line carrier signal onto the distribution line. The power line carrier signal transmitter can communicate information associated with the load control device and information associated with one or more electrical devices that are controlled by the load control device to a remote device. The information may be transmitted from the load control device to the remote device in response to a request received by the load control device or on a periodic basis.
