FIELD: electrical engineering; generator voltage regulation while throwing it on line. ^ SUBSTANCE: novelty is that automatic voltage regulator that has generator voltage rectifier, supply mains voltage rectifier, inverter, multiplier, algebraic adder, and first comparator is provided with newly introduced second comparator, and that subtraction and addition inputs of algebraic adder are connected to outputs of generator voltage rectifier and supply mains voltage rectifier, respectively, algebraic adder output is connected to first inputs of first and second comparators, output of supply mains voltage rectifier is connected to input of multiplier whose output is connected through inverter to second input of first comparator and directly to second input of second comparator. Signal affording reduction of generator voltage is shaped across LOW output of first comparator and that affording generator voltage rise, across HIGH output of second comparator; multiplier functions as constant multiplier. ^ EFFECT: enhanced precision of device due to response to relative inadmissible difference between generator and supply voltages. ^ 1 cl, 1 dwg |
