  • Publication number: 20210321502
    Abstract: A zero-crossing detection method, and devices incorporating the method, enable a selectively enabled bias to pull-up a zero-crossing signal, thereby enabling monitoring of the zero-crossing of both half-cycles of the alternating current (AC). This improves synchronization of the device in noisy environments and enables the detection of dimming problems during either half-cycle. Aspects can detect improper dimmer firing events on either polarity of the power cycle and restore normal dimmer operations when needed.

  • Patent number: 11128115
    Abstract: The present disclosure relates to arc fault detection in an electrical switch apparatus. In aspects of the present disclosure, an arc fault electrical switch apparatus includes a conductive path, a switch configured to interrupt electrical current in the conductive path, a current sensor in electrical communication with the conductive path and configured to measure the electrical current to provide current measurements, and a controller. The controller is configured to execute instructions to sample the current measurements to provide current samples, computing an estimated signal-to-noise ratio of the electrical current based on at least a portion of the current samples, determine whether the signal-to-noise ratio is less than a predetermined threshold, and activate the switch to interrupt the electrical current in the conductive path, if the signal-to-noise ratio is less than the predetermined threshold.

  • Publication number: 20210105882
    Abstract: Two-wire dimmer operation includes controlling conduction of power to a lighting load. In one aspect, based on a conduction angle adjustment, power supply voltage is monitored and a maximum conduction angle is established based thereon. In another aspect, a dimming level signal is received and a dimming level for a dimmer is set based on the received dimming level. The dimming level signal indicates a desired dimming level for a dimmer, and a maximum value for the dimming level signal is based on a dimmer power supply voltage. In yet another aspect, based on detecting an adjustment to increase a conduction angle of a dimmer, the conduction end angle is increased and the conduction start angle is also increased. This results in a net increase in the conduction angle for controlling operation of the dimmer.

  • Patent number: 10641812
    Abstract: An apparatus includes an interruption circuit in a power delivery path, and a fault detection circuit configured to provide a fault signal to selectively cause the interruption circuit to interrupt power delivery, wherein the fault detection circuit includes a fault detection integrated circuit and a sensing coil configured to sense a differential current between a phase conductive path and a neutral conductive path in the power delivery path. A processor is configured to selectively control a fault simulation circuit to simulate a fault in the power delivery path, detect a response of the fault detection circuit to the simulated fault, and determine if the response of the fault detection circuit is an expected response. The processor provides an override signal to the interruption circuit to prevent the interruption circuit from receiving a fault signal from the fault detection circuit during, and for a predetermined time after, the simulated fault.

  • Patent number: 10568185
    Abstract: Two-wire dimmer operation includes applying first and second control pulses to a switching circuit controlled between ON and OFF states, the first control pulse beginning at a first starting time and extending for a first duration of time that ends at a first ending time, and the second control pulse beginning at a second starting time, after the first ending time, and extending for a second duration of time that ends at a second ending time, detecting levels of current provided to a lighting load during the first duration of time and during the second duration of time, comparing current levels determined based on applying the first and second control pulses, based on the comparing, ascertaining a load type of the lighting load, and selecting, based on the ascertained load type, parameters that control dimming operation of the dimmer.
