Some stabilizers use a transformer with taps on winding to provide different voltage corrections while servo stabilizers use an auto transformer to have wide range of correction. To understand this concept, let us consider simple step down transformer of 230/12V rating and its connection with these operations are given below. filexlib. Shuogong Power is the best automatic voltage stabilizer manufacturer in China, we supply affordable single-phase and 3-phase automatic voltage stabilizers. Can meet your voltage stabilization needs. However, in the case of an autotransformer type stabilizer, the motor (servo motor) is used with sliding contacts to get a boost or step down automatic voltage stabilizer. Measuring unit includes control circuit. The function of the measuring unit is that of detection a change in the input or output voltage of the automatic voltage stabilizer and producing a signal to operate the regulating unit. Fig. 2 show the block diagram of a measuring unit of automatic voltage stabilizer.

Autotransformer Terminal Markings. An autotransformer is used mainly for the adjustments of line voltages to either change its value or to keep it constant. If the voltage adjustment is by a small amount, either up or down, then the transformer ratio is small as VP and VS are nearly equal. Currents IP and IS are also nearly equal.
Single-phase tapped autotransformer with an output voltage range of 40%-115% of input An autotransformer is an electrical transformer with only one winding. The "auto" (Greek for "self") prefix refers to the single coil acting alone, not to any kind of automatic mechanism.
The main implementation of this paper is the design of variable autotransformer and buck-boost transformer. Three identical 20 kVA automatic voltage stabilizers are needed to get 60 kVA automatic voltage stabilizer. So, 20 kVA rating is designed. This stabilizer will operate within the fluctuation range from 130 V to 250 V.
AC voltage stabilizers, DC voltage stabilizers, and automatic voltage stabilizers are the three types of voltage stabilizers[3]. Static voltage, an ac voltage stabilizer, is the subject of this paper. The most commonly used stabilizer is the servo stabilizer, which has a number of drawbacks as compared to static voltage stabilizers[4].
At voltages within the specific input voltage range, the stabilizer gave an output voltage of 220 VAC (±6%) and voltages outside the specified input range, the over/under voltage protection prevents power from being supplied to the autotransformer thus making the stabilizer output to be 0 V.
