    • A lighting control circuit is provided for controlling illumination and dimming of at least one light in a lighting circuit for operation at a selectable one of a plurality of applied voltages. The lighting control circuit includes a power supply circuit for receiving an AC line voltage input and for converting the AC line voltage to selectable rectified AC and DC power for delivery to the lighting control circuit. A timing generator circuit is also coupled with the power supply circuit and is responsive to a rectified AC sample from the power supply for generating and shaping an electrical timing signal. A timing comparator circuit is responsive to the electrical timing signal for generating a variable duty cycle output signal. A switching control circuit is coupled with the lighting circuit for gating current therethrough in accordance with the variable duty cycle output control signal.

    • An improved method and apparatus for handling the large load currents which occur with overloads, short circuits, and momentary overcurrents such as in starting motors or cold incandescent lamp filaments. The method involves turning the load current off when an overcurrent is detected, and then back on again before the end of the half-cycle in which the overcurrent occurred. This allows more current to flow during the half-cycle without the need to increase the peak current capability of the power-handling components. With an incandescent lamp load, this results in more rapid lamp brightening without the need for larger, more expensive components. Several embodiments are disclosed which respond to different features of the power line voltage cycle, including a very low-cost microprocessor circuit and power supply.
    • 一种用于处理由过载,短路和瞬时过电流引起的大负载电流的改进方法和装置,例如起动电动机或冷白炽灯灯丝。 该方法涉及当检测到过电流时关闭负载电流,然后在发生过电流的半周期结束之前再次接通。 这允许在半周期期间更多的电流流动,而不需要增加功率处理组件的峰值电流能力。 使用白炽灯负载,这将导致更快速的灯泡增亮,而不需要更大,更昂贵的组件。 公开了响应电力线电压周期的不同特征的几个实施例,包括非常低成本的微处理器电路和电源。

    • An improved phase-controlled power control apparatus includes a semiconductor switching element for varying the effective power delivered to a load from the power lines. The conduction angle of the semiconductor power switch element is varied from a nominal angle to compensate for changes in power line voltage and for changes in load current. The amount of load current flow is continuously compared to the power line voltage to detect any overcurrent condition, even very close to the zero-crossing of the power line voltage. The shape of the transition from load current on to load current off (or vice versa) in controlled to minimize audible noise from the load. The load current can be shared between a plurality of compatible power control sections.
    • 一种改进的相位控制功率控制装置包括用于改变从电力线传送到负载的有效功率的半导体开关元件。 半导体功率开关元件的导通角从额定角度变化,以补偿电力线电压的变化和负载电流的变化。 负载电流流量与电力线电压持续比较,以检测任何过电流状态,即使非常接近电力线电压的过零点。 从负载电流转换到负载电流关闭(或反之亦然)的形状被控制以最小化来自负载的可听噪声。 负载电流可以在多个兼容功率控制部分之间共享。
