Design and construction of Automatic Voltage Regulator

Abstract

In some developing nations of the world, problem with electric power system and its operation; most often, characterizes the main issue that poses a lifelong and protracted economic decrepitude of those nations. This menace, so to say, reflects on almost all facet of their economy at all times to decelerate productivity. Apart from what seems to be almost ‘all - day(s)’ generation failure, transmission failure and the associated recurrent total city black-out, voltage-profile degradation among other ailments, contributes in no small measure against what supposes to be a healthy culture of full capacity electricity supply and usage at tertiary power consumption areas - the homes. This work aims at proffering a solution on how power fluctuations can be handled in order to ensure voltage stability for home appliances. And so, a wide and appreciable volume of discussion are made here to precipitate a broad- range of understanding on how to design a hybrid of power and electronic circuits that yields a composite system with the capability of erasing voltage fluctuations and other power related irregularities which afflicts domestic electrical equipments. As a result, the design, construction and functional mechanisms of Autotransformer as the principal power device and electronic control circuits are thoroughly evaluated with greater attention on their principle of operation in order to create a comprehensive knowledge on how to achieve a device that ensures a steady voltage magnitude of 230V within a possible voltage variation range of 90V to 230V.
