It saves the life of costlier appliances, CNC machines, electrical equipment, medical equipment, motors lab equipment etc. through connecting AC voltage which is not stabilized, and dips at one point of time and at other point of time rises to very high value.It involves comparing the output voltage with built in stable reference voltage source. The solid state control circuit operates the motor whenever the output voltage falls or rises beyond the preset voltage.  Servo voltage stabilizer features a microcontroller based circuit to control the AC Synchronous Servo Motor. The motor is mechanically attached to the arm of a continuously variable auto transformer which feeds to the primary of a series control buck boost transformer. The stabilizer output voltage is compared with the reference voltage & resultant error signal controls the Servo Motor providing true proportional control systems rather than on/off circuit.
