This project is on The construction of a 2kva automatic voltage regulator (AVR). The AVR is automatic voltage regulator and it is a device which is used to regulate or stabilize electrical power supply for electrical or electronic appliances. In this project, therefore, we are interested in the construction of this all important device. Furthermore, we shall discuss the techniques, processes, switching stages and then the working principle of the automatic voltage regulator. Chapter one of this project dwells on the introduction of the project topic. It also talks about the objectives of the project, bringing to mind what we intend to achieve at the end. Chapter two of the project reviews the research works that have been carried out by some other people in this study area. It also discusses on some of the components used in this project. Chapter three gives a detailed account of the basic construction and the operation of the AVR. It also highlights on some other components used, discussing their working principles using both the circuit and block diagrams. Chapter four of this project draws the conclusion and consequently gives the recommendation on how to better the operation of the AVR. It also includes the references and articles consulted in the course of this project.
