Abstract
An r.m.s. voltage regulating circuit for maintaining substantially constant the r.m.s. output voltage of an A.C. source. The circuit preferably includes a triac and a timing circuit for controlling the non-conduction angle thereof, preferably at the beginning of each half cycle. A function generator compensates for the non-linearity in the relationship between the r.m.s. value of the output voltage and the amplitude of the A.C. voltage source.
