Abstract: A load control device for controlling power delivered from an AC power source to an electrical load includes a thyristor, a gate coupling circuit for conducting current through a gate terminal of the thyristor, a controllable switching circuit coupled between first and second main terminals of the thyristor, and a control circuit for controlling the gate coupling circuit to conduct a pulse of current through the gate terminal to render the thyristor conductive at a firing time during a half cycle. The gate coupling circuit is able to conduct at least one other pulse of current through the gate terminal after the firing time until a transition time before an end of the half-cycle. The control circuit is configured to render the controllable switching circuit conductive to conduct current through the electrical load between approximately the transition time until approximately the end of the half-cycle.

Abstract: A load control device may control the amount of power provided to an electrical load utilizing a phase control signal that operates in a reverse phase control mode, a center phase control mode, and a forward phase control mode. A load control device may be configured to determine that the electrical load should be operated via a phase control signal operating in a forward phase-control mode. After determining to operate the electrical load via the phase control signal in the forward phase-control mode, the load control device may provide the phase control signal in a reverse phase-control mode for a predetermined period of time to the electrical load, for example, to charge a bus capacitor of the electrical load. Subsequently, the load control device may be configured to switch the phase control signal to the forward phase-control mode and provide the phase control signal in the forward phase-control mode to the electrical load.

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 comprising two MOS-gated transistors, and a control circuit. The control circuit generates first and second drive voltages for individually controlling the MOS-gated transistors, and controls the gate coupling circuit to cause the MOS-gated transistors to conduct a pulse of current through a gate terminal of the thyristor to render the thyristor conductive at a firing time during a present half cycle of the AC power source, and to allow the MOS-gated transistors to conduct at least one other pulse of current through the gate terminal after the firing time during the present half cycle.

Abstract: A motorized window treatment provides a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment includes a covering material, a drive shaft, at least one lift cord rotatably received around the drive shaft and connected to the covering material, and a motor coupled to the drive shaft for raising and lowering the covering material. The window treatment also includes a spring assist unit for assisting the motor by providing a torque that equals the torque provided by the weight on the cords that lift the covering material at a position midway between fully-open and fully-closed positions, which helps to minimize motor usage and conserve battery life if a battery is used to power the motorized window treatment. The window treatment may comprise a photosensor for measuring the amount of daylight outside the window and temperature sensors for measuring the temperatures inside and outside of the window. The position of the covering material may be automatically controlled in response to the photosensor and the temperature sensors to save energy, or may also be controlled in response to an infrared or radio-frequency remote control.

Abstract: A circuit for controlling a lighting load may operate to minimize flicker in the lighting load and electromagnetic interference (EMI) noise generated on an AC voltage supply for the lighting load. The circuit comprises a bus-voltage-generating circuit for generating a bus voltage, a load regulation circuit having an inverter circuit, and a high speed control circuit characterized by a cutoff frequency much greater than a frequency of a voltage ripple on the bus voltage. The control circuit may comprise an error amplifier circuit configured to spread the frequency of operation of the inverter circuit at a set intensity level of the lighting load into a spread spectrum of frequencies to reduce the time average of peaks of the spectrum of frequencies and peak EMI levels. The circuit may also comprise a non-linear amplifier circuit amplifying a lamp-current-feedback signal representative of the magnitude of the load current through the lighting load.
