Description of Auto Voltage Stabilisers

The auto voltage stabilizer system is designed to operate with rated voltage in accordance and is expected to be connected between main power supply and load.
The purpose is to supply the loads a stabilised voltage having an input voltage variable with respect to the rated value. The highest input current is obtained with the minimum rated voltage; as the output voltage is stabilised within a close range, the output current is considered to be constant. This auto load booster takes place on the ‘rms’ value of the voltage and is not affected by harmonic distortion in the mains.
