ABSTRACT:
Improved circuitry for regulating the average power supplied by an AC source to a load includes switching circuitry that the power applies to the load for integral numbers of full cycles of the AC source. Control of the circuit for switching the power on and off is accomplished by sensing and storing the peak current drawn by the load during the most recent application of power, reducing the stored quantity linearly with time, and causing another application of power wnen the stored quantity has dropped below a predetermined threshold.
