ALTERNATING VOLTAGE REGULATOR Russian patent published in 2012 - IPC G05F1/10 

FIELD: electricity.

SUBSTANCE: into alternating voltage regulator containing control element of step-by-step action actuated between inputs and outputs, and also counter, sync pulse former connected by input to input outputs and by output to counter inverting input, and comparing unit which first input is connected to output of duration codes converter and the second input is connected to counter output, there included are two units "log. AND" and unit "log. OR", RS-trigger, which setting input is connected to comparing unit output, and reset input is connected to high-order bit with counter output, direct and inverse outputs of trigger are connected to inputs of units "log. AND", converter of reference level codes to which input control code is sent and which output is connected to input of unit "log. AND", converter of final level codes to which input control code is sent and which output is connected to input of unit "log. AND", converter of duration codes to which input control code is connected.

EFFECT: improving accuracy of root-mean-square voltage control.
