Servo-controlled voltage stabilizers are known as servo stabilizers that use servo motor for voltage correction. These stabilizers consist of a servo motor, buck-boost transformer, auto transformer, control circuitry, and motor driver as essential components. In this stabilizer, the electronic control circuit detects voltage fluctuation and in case of error, the circuit operates a motor that moves the arm on the autotransformer. This feed primary of buck-boost transformer in a way that voltage across secondary should be the desired voltage output. The servo stabilizers use a microcontroller or processor so that control circuitry can achieve intelligent control.
