  • Publication number: 20190372619
    Abstract: A power line communication architecture for indoor environment having a power cable includes two filters, one of the filters disposed between the power cable and an indoor circuit and the other filter including an independent sub filter connected in series between an external device and the indoor circuit and an integrated sub filter disposed in an original device. The power line communication architecture further includes a signal coupling and isolation module, a signal receiving and transmitting module and a digital signal processing module. The signal coupling and isolation module loads a control signal into a power line or extracts the control signal from the power line. The signal receiving and transmitting module digitalizes an analog signal extracted from the power line by the signal coupling and isolation module. The digital signal processing module digitally processes and exchanges signals obtained from power lines for A and B phases.

  • Publication number: 20190372621
    Abstract: A structure for preventing bus signals from being affected by conditions of a device load during circuit signal transmission includes a filter, a signal channel, a power channel, a CPU, and a power source. The filter separates power and signals and forms the signal channel and the power channel. The signal channel provides an access for a control signal to enter and exit, and the power channel provides power for a power supply and a load controlling output of a device. The power channel blocks the control signal, and the signal channel blocks power so as to prevent the control signal of a power line from being attenuated due to an overload occurred in the device.

  • Publication number: 20190372620
    Abstract: A lossless coupling structure of power line communication signals between different phase lines includes two signal coupling and isolation modules, two signal receiving and transmitting modules, and a digital signal processing module. The signal coupling and isolation modules load a control signal into a power line or extract from the power line, and isolate alternating current. The signal receiving and transmitting modules digitalize an analog signal extracted from the power line by the signal coupling and isolation modules to be loaded into the power line. The digital signal processing module digitally processes and exchanges signals obtained from power lines for A and B phases.

  • Publication number: 20100320926
    Abstract: A light modulation control method applied to control a lamp is disclosed. The control method includes the following steps: first, providing an AC voltage; then, rectifying the AC voltage into a first DC pulse; modulating the first DC pulse into a modulated wave; filtering the modulated wave into a second DC pulse; finally, alternatingly switching the second DC pulse to a modulated AC voltage for the lamp through a switching unit.
