Design And Construction Of An Automatic Voltage Regulator

This project proposes a new type of voltage regulator based on single-phase converter otherwise known as transformerless AVR that compensates wide range voltage variations. This is not only capable of compensating variations at a much higher bandwidth but also does not experience mechanical wear down and is cost effective. The proposed device employs a pulse width modulation (PWM) z-source ac–ac converter along with a simple closed loop control. High speed MOSFETs are used as bi-directional switch of the ac–ac converter and the circuit ultimately can easily and steadily maintain regulated volt…
