VARIABLE VOLTAGE CONTROLLER Russian patent published in 2010 - IPC G05F1/00 

FIELD: electrical engineering.

SUBSTANCE: proposed controller comprises discrete regulator connected between input and output terminals, ADC with its input connected to control signal terminals, counter, sync pulse generator with its input connected to input terminals and its output connected to counter counting input. It comprises also "log. 0" signal source, adder with its first input connected to top digits of ADC and its output connected to discrete regulator control inputs, comparator with its first input connected to ADC low-order digits and its second input connected to counter output, while its output is connected to low-order digit of adder second input. Adder top digits are connected to "log. 0" signal source output. Additionally, proposed control comprises code converter with its input connected to ADC top-digit outputs and its output connected to counter setting input.

EFFECT: reduced adjustment error.
