ABSRACT - [ Total Page(s): 1 ]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

CHAPTER ONE - [ Total Page(s): 1 ]CHAPTER ONE BACKGROUND OF THE WORK In the world today for example our country Nigeria, the electricity power delivered to consumers either at their homes or offices is not upheld at an agreed voltage approximately 220volts as a result of voltage fluctuation from the supply of the power system. This voltage fluctuation occurs as a result of sudden changes in the real and reactive power drawn by loads. This fluctuating current that is drawn from the supply causes an additional voltage drops in the power system leading to fluctuation in the supply voltage [1]. Ne ... Continue Reading
