There are a variety of system designs available today to control AC voltage for sensitive loads, such as an AC PWM chopper, a unified power factor converter made up of a PWM rectifier and a PWM inverter, or a serial AC voltage regulator, among others. Serial AC voltage regulators can lower the switching strength and rating of the main circuit power devices in these arrangements. It has the smallest rating, which is determined by load capacity and the fluctuating range of supply voltage. As a result, it is rated for significant rating loads. This paper is review the different techniques for voltage regulator used in power system for voltage profile control. In this paper, the techniques based on artificial intelligence, fuzzy logic, using auto transformer, 9 step level; voltage regulator, coordinated control, predictive control method etc. This paper will be useful in future for students and researcher those interested in work in field of voltage regulator.
