Air Cooled Servo Voltage Stabilizers

In Servo controlled voltage Stabilizer, one end of buck-boost Transformer primary is connected to the fixed tap of the auto Transformer, while other end is connected to the moving arm that is controlled by the servo motor. Secondary of the buck boost Transformer is connected in series with incoming supply which is nothing but Stabilizer output.

Electronic control circuit detects the voltage dip and voltage rise by comparing the input with built-in reference voltage source. When the circuit finds the error, it operates the motor that in turn moves the arm on the autoTransformer. This could feed the primary of buck boost Transformer such that a voltage across the secondary should be the desired voltage output. Our servo Stabilizer use embedded microcontroller or processor for the control circuitry to achieve intelligent control.
