How does this Servo Voltage Stabilizer, Power Regulators and controllers Operates?

These types of Servo Stabilizers and power controllers essentially employ a Solid-State circuit, which controls the Servo Motor. The motor is mechanically coupled to the arm of a continuously variable Auto Transformer (Variacs) that feeds to the primary of a series control Buck-Boost transformer. The stabilizer / regulator output voltage is then compared with the reference voltage and the resultant error signal controls the Servo Motor providing true proportional control systems rather than On/off circuits.

Types of Servo Voltage Stabilizer and Power Controllers ?
UNBALANCED TYPE: Widely accepted design to suit various conditions. All the phase/s are independently sensed & corrected. Suitable for both balanced/ unbalanced loading & incoming voltage
BALANCE TYPE: One phase (master) sensed & all the 3 corrected in accordance to the master phase. Suitable for balanced loading & balanced incoming voltage only (not suitable for unbalanced loading/unbalanced input voltage)
