摘要： 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.

摘要： Timer-based switching circuit synchronization in an electrical dimmer is provided. The energizing of a switching circuit in a dimmer is synchronized with an AC wave to facilitate providing by the dimmer electrical power to a load. The synchronizing includes starting a timer having a predetermined timeout, responsive to receipt of a zero-crossing signal. Responsive to receipt of a subsequent zero-crossing signal prior to reaching the timeout, the timer is restarted, and responsive to expiration of the timeout, a switching circuit is energized at a predetermined firing angle with respect to the zero-crossing signal to supply electrical power to the load.
