Claims

[Scope of utility model registration request]

In an AC voltage regulator that adjusts the voltage on the line output side by applying the output of the main transformer to which the line voltage is applied to the transformer in series with the line through an AC thyristor switch, including polarity switching, the line output side A detection circuit that detects the deviation between the voltage setting value and the detected value, a comparison circuit that detects that the detection value of this detection circuit exceeds the voltage fluctuation range allowed on the line output side, and the detection output of this comparison circuit. 1. A control device for an AC voltage regulator, comprising: a counter circuit that increases or decreases the count content according to the following steps; and a decoder that decodes the count content of the counter circuit to obtain a thyristor gate control signal of the AC thyristor switch.
