Abstract: A two-wire load control device (such as, a dimmer switch) for controlling the amount of power delivered from an AC power source to an electrical load (such as, a high-efficiency lighting load) includes a thyristor coupled between the source and the load, a gate coupling circuit coupled between a first main load terminal and the gate of the thyristor, and a control circuit coupled to a control input of the gate coupling circuit. The control circuit generates a drive voltage for causing the gate coupling circuit to conduct a gate current to thus render the thyristor conductive at a firing time during a half cycle of the AC power source, and to allow the gate coupling circuit to conduct the gate current at any time from the firing time through approximately the remainder of the half cycle, where the gate coupling circuit conducts approximately no net average current to render and maintain the thyristor conductive.

Abstract: A two-wire load control device (such as, a dimmer switch) is operable to control the amount of power delivered from an AC power source to an electrical load (such as, a high-efficiency lighting load) and has substantially no minimum load requirement. The dimmer switch includes a bidirectional semiconductor switch, which is operable to be rendered conductive each half-cycle and to remain conductive independent of the magnitude of a load current conducted through semiconductor switch. The dimmer switch comprises a control circuit that conducts a control current through the load in order to generate a gate drive signal for rendering the bidirectional semiconductor switch conductive and non-conductive each half-cycle. The control circuit may provide a constant gate drive to the bidirectional semiconductor switch after the bidirectional semiconductor switch is rendered conductive each half-cycle. The bidirectional semiconductor switch may comprise, for example, a triac or two field-effect transistors coupled in anti-series connection.

Abstract: Provided herein are examples of a remote control device that provides a retrofit solution for an existing switched control system. The remote control device may comprise a control circuit, a rotatable portion, a magnetic ring coupled to the rotatable portion, and first and second Hall-effect sensor circuits configured to generate respective first and second sensor control signals in response to magnetic fields generated by the magnetic elements. The control circuit may operate in a normal mode when the rotatable portion is being rotated, and in a reduced-power mode when the rotatable portion is not being rotated. The control circuit may disable the second Hall-effect sensor circuit in the reduced-power mode. The control circuit may detect movement of the rotatable portion in response to the first sensor control signal in the reduced-power mode and enable the second Hall-effect sensor circuit in response to detecting movement of the rotatable portion.
