Abstract
An RMS regulation system for power supplies characterized by a digital loop feedback of a quickly sampled peak crest voltage value of a trapezoidal waveform, whereby a microprocessor controls either the timing of, or rate of, the trapezoidal waveform rise/fall time in order to modulate the crest width of succeeding waveform outputs and provide RMS voltage regulation.
