A Voltage Stabilizer is an electrical device which is used to provide a constant voltage output to a load at its output terminals irrespective of any change/ fluctuation in the input i.e. incoming supply.A Static Voltage stabilizer has no moving parts as in case of Servo based Voltage Stabilizers. It uses a Power Electronic Converter Circuit to stabilize the voltage. These Static Voltage Stabilizers have very high accuracy and the voltage stabilization is within ±1%.This is the latest technology of voltage regulation to provide real-time control of voltage fluctuation, sag, surge and also to control other power quality issues such as spikes and EMI/RFI electrical noises. This uses an IGBT regulator engine generating pulse width modulated (PWM) AC voltage at high switching frequency. This AC PWM wave is superimposed on the main incoming wave through a buck-boost transformer, to provide precisely regulated AC voltage. The regulation in this technology is instantaneous, thus making it suitable for electronic machines which need precise regulated power.
