Yesterday Gechy Electric Co.,Ltd share the different components of servo stabilizer and its functions. Today we continue to tell the Working of Servo stabilizer or stablizer.

To understand working of servo stabilizer please note that voltage across secondary of Buck Boost transformer is nothing but output voltage of stabilizer. It work as follow:

◆ Voltage received from main at input of automatic voltage regulator is continuously sensed by accessories circuitry and gives feedback to Main control circuitry which consists of Microprocessor. This microprocessor continuously receives values of input voltages. Whenever there is high or low voltage at input of AVR automatic voltage regulator, the microprocessor gives trigger to motor driver.

◆ Based on amount of high voltage or low voltage observed at input, “motor driver” moves servo motor across winding of autotransformer so as to increase of decrease no of winding and hence voltage across primary of buck boost transformer. It is since Servo motor shaft is connected to primary of buck boost transfer.

And hence when there is change in voltage across primary of buck boost transfer then induce voltage across its secondary also changes. The motor moves in such a way that proper voltage should be observe across primary of Buck Boost transformer so that voltage across secondary should be equal to set or desired output voltage of servo stabilizer. And voltage across secondary of Buck Boost transformer is output voltage of stabilizer.

◆ This process takes place continuously so as to correct input voltages.

◆ In case of 3 Phase automatic Voltage Regulator is independent phase controlled then it will have above arrangement for all three phases separately. It means it is as good as 3 number of Single phase servo stabilizer in one unit.

As explained above servo stabilizer works. Gechy Electric  is  reputed Three Phase Servo Stabilizer suppliers in all over the world.
