PREDICTION AND RECOVERY OF ZERO-CROSSING INFORMATION AND SELECTIVE CONTROL SIGNAL PULSE DURATION

Operating an electrical load controller includes determining a firing angle at which to fire a switching circuit of the electrical load controller, the firing angle corresponding to a firing delay time. In some aspects, the operating includes selecting a control signal pulse duration between a fixed...

More Information
Summary:Operating an electrical load controller includes determining a firing angle at which to fire a switching circuit of the electrical load controller, the firing angle corresponding to a firing delay time. In some aspects, the operating includes selecting a control signal pulse duration between a fixed duration and a variable duration, and controlling the supply of AC power to the load based on the selected control signal pulse duration. In some aspects, the operating includes detecting whether a voltage sag is present in the AC waveform and the selecting is based on determining that voltage sag is present in the AC waveform.
