AC VOLTAGE REGULATOR Russian patent published in 2013 - IPC G05F1/00 

FIELD: electricity.

SUBSTANCE: AC voltage regulator comprises a control element of discrete action, connected between input and output leads, and also a counter, a clock driver connected with an input to input leads, and with an output - to the count input of the counter, and a circuit of code comparison, the first input of which is connected to the output of the calculation unit, the second input - to the counter output, and the following components are introduced: a unit of existing value meters, outputs of which are connected to inputs of analogue comparators and to inputs of two analogue multiplexors, a combination device, inputs of which are connected to outputs of analogue comparators, and the output is connected to one of inputs of a summator and address inputs of analogue multiplexers, a unit of analogue comparators, two multiplexors, outputs of which are connected with inputs of the ADC unit, to the input of which a signal is also connected from a setpoint setter, a calculation unit, to inputs of which ADC outputs are connected, and the output is connected to one of inputs of the code comparison circuit, and a setpoint setter.

EFFECT: increased stability of existing voltage value at a regulator output.
