Servo Controlled Voltage Stabilizer (SCVS)

The Servo Controlled Voltage Stabilizer incorporates an auto transformer paired with a motor and a Buck Boost Transformer. The Buck Boost Transformer features two windings: the primary and the secondary. The primary winding is connected to the Auto Variable Transformer, and the secondary winding is connected in series with the supply line.

The primary voltage of the Buck Boost Transformer is regulated by adjusting the position of the moving arm of the auto transformer, facilitated by the motor. This arrangement allows for precise control over the addition or subtraction of line voltage.
