ABSTRACT:
A method and apparatus for regulating the RMS voltage applied to a load from an AC source having a peak-to-peak amplitude which varies within a predefined range. The apparatus comprises a waveform generator for producing a predefined periodic waveform, a comparator circuit for comparing such waveform with the sinusoidal waveform of the source whereby a signal is produced each time the algebraic difference between the instantaneous values of the compared waveforms changes sign, and a switching circuit responsive to the comparator circuit output for interrupting the voltage applied to the load at the start of each cycle or half-cycle. The shape of the waveform produced by the waveform generator is such that the desired RMS voltage appearing at the output terminals is produced.
