ALTERNATING VOLTAGE STABILIZER Russian patent published in 2007 - IPC H02M5/22 

FIELD: electric engineering, possible use for controlling voltage, in particular, in precise, fast action stabilizers of alternating voltage.

SUBSTANCE: alternating voltage stabilizer includes input and output clamps, transformer-switching controlling organ, inputs of which are connected to input clamps, analog-digital converter, measuring organ, input of which is connected to output clamps, digital-analog converter and impulse modulator, coupled between outputs of transformer-switching controlling organ and output clamps, control input of impulse modulator is connected to output of digital-analog converter, inputs of which are connected to outputs of second group of outputs of analog-digital converter, outputs of first group of outputs of which are connected to control inputs of transformer-switching controlling organ, input of analog-digital converter is connected to output of measuring organ.

EFFECT: increased precision.
