ALTERNATE VOLTAGE CONTROLLER Russian patent published in 2008 - IPC G05F1/20 H02M5/12 

FIELD: physics.

SUBSTANCE: alternate voltage controller includes discrete adjusting element connected between input and output, analog-to-digital converter with input connected to control signal outputs, counter, locking pulse shaper with input connected to device inputs and output connected to zero counter setting input, code converter with input connected to counter output, 'log.0' signal generator, adder with first input connected to high orders of analog-to-digital converter and output connected to control inputs of discrete adjusting element, and comparator with first input connected to low order output of analog-to-digital converter, second input connected to code converter output and output connected to low order input of second adder, high order of which is connected to 'log.0' signal generator output. Additionally the controller features cascade of rectifier with input connected to device outputs and voltage-controlled generator with output connected to counter input.

EFFECT: improved adjustment regularity of industrial power network with distorted voltage type.
