摘要： A load control device for controlling the power delivered from an AC power source to an electrical load includes a thyristor, a first current path for conducting current through a gate terminal of the thyristor, and a control circuit for controlling the first current path to conduct a pulse of current through the gate terminal to render the thyristor conductive at a firing time during a half cycle. The first current path is able to conduct at least one other pulse of current through the gate terminal again after the firing time until, a transition time before the end of the half-cycle, but prevented from conducting pulses of current after the transition time until the end of the half-cycle. The load control device may comprise a second current path for conducting current through the electrical load between the transition time and the end of the half-cycle.

摘要： A multiple location load control system comprises a main device and remote devices, which do not require neutral connections, but allow for visual and audible feedback at the main device and the remote devices. The main device and the remote devices are adapted to be coupled in series electrical connection between an AC power source and an electrical load, and to be further coupled together via an accessory wiring. The remote devices can be wired on the line side and the load side of the load control system, such that the main device is wired “in the middle” of the load control system. The main device is operable to enable a charging path to allow the remote devices to charge power supplies through the accessory wiring during a first time period of a half-cycle of the AC power source. The main device and the remote devices are operable to communicate with each other via the accessory wiring during a second time period of the half-cycle.

摘要： A two-wire load control device (such as, a dimmer switch or an electronic switch) for controlling the power delivered from an AC power source to an electrical load includes a controllably conductive device for controlling the power to the load, a microprocessor operable to generate a control signal that is representative of whether the load should be controlled on or off, a capacitor operable to produce a supply voltage for powering the microprocessor, a power supply that charges the capacitor when the controllably conductive device is non-conductive, and a control circuit that receives the control signal from the microprocessor. The control circuit is operatively coupled to the controllably conductive device for maintaining the controllably conductive device non-conductive after the beginning of each half-cycle until the magnitude of the supply voltage exceeds a predetermined threshold.
