ALTERNATING VOLTAGE ADJUSTER Russian patent published in 2005 - IPC

FIELD: electric engineering.

SUBSTANCE: device includes discontinuous action adjusting tool, switched in between input and output contacts, and analog-digital converter, connected by input to outputs for connecting control signal, as well as synchronizing pulses forming device and circuit of, connected in cascade, frequency multiplier, pulse forming device and counter, and comparator and adder, first input of which is connected to output of higher digits of analog-digital converter, lower digit of second input - to comparator output, and higher digits - to special signals source, while output of device for forming synchronous pulses is connected to zero mounting tool of counter, adder output - to control input of discontinuous action adjusting tool, and first input of comparator - to output of lower digits of analog-digital converter. Additionally, device contains codes converter, connected by input to counter output, and by output - to second comparator input, and first and second decoders, connected by inputs to counter output, while output of first decoder is connected to input for controlling counter subtraction, and output of second one - with signal for controlling its summing.

EFFECT: higher efficiency.
