ABSRACT - [ Total Page(s): 1 ]ABSTRACTThis project presents the design and construction of a DC to AC inverter system. It is designed to meet up with the power demand in the offices/homes in the absence of power supply from National Supply Authority.It is designed in such a way that it will take up to 12V DC from battery and inverts it to an output of 220V, 50Hz AC. It makes no noise during operation and not hazardous like carbon monoxide is generated to the surrounding. This is the feature makes it safe to used anywhere when compared to generator. Also, the circuit is capable of charging the battery [i.e 12V source]

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONEINTRODUCTION1.2 Background of the Study An inverter is an electronics device or circuitry that changes direct current (D.C) to Alternating current [AC]. The device make used of an in–built automatic circuit to achieve a complete automation of the entire system. The input voltage, output voltage, frequency and overall power handling depend on the design of a specific device or circuitry. An inverter is very important element that cannot be neglected in this Country as it is deeply fasten into the fabric of the society for the obvious reason of inadequate power supply. It ...

CHAPTER TWO - [ Total Page(s): 2 ]CHAPTER TWOLITERATURE REVIEW2.0 INVERTER An enabling technology, power electronics does it job with intelligence, precision and efficiency. It used the smartness of advanced control technology with the efficient conversion of electric power into the precise from required to control a function or process. In a industrial and commercial products, it is gaining ground mostly visible among inverters which converts direct current (DC) into a single or poly phase AC voltage at a desire aptitude and frequency whose power rating now runs from 1000W, 20MW and more.The operation of certain devi ...

CHAPTER THREE - [ Total Page(s): 9 ]There are two main categories of transistor:1. Bipolar junction transistor (BJT): it also divided into NPN and PNP transistors.2. Field effect transistor (FET): it has three terminal unipolar solid state device in which current is controlled by an electric field as is done in vaccum tubes (http://www.amplifieredparts.com/2017/05/27 product/transistor.tip416-npn-epitaxial-transistors).There are two types of FETs.a. Junction field effect transistor (JFET)Metal-oxide semi-conductor field effect transistor (MOSFET) is also called insulated gate FET(IGET). MOSFET require v ... Continue Reading
CHAPTER FOUR - [ Total Page(s): 4 ]DETERMINATION OF TRANSFOMER CAPACITY T.C= (A^2 X 31)/(p.f)= (6^2 X 31)/0.7= (36 X 31)/0.7= 1116/0.7=1594.28=1600W DETERMINATION OF TRANSFORMER RATIO = 8/A=8/6 = 1.33Therefore 8 is a constant value DETERMINATION OF NUMBER OF CURRENT Ip = Transformer capacity / primary voltage = 1600/12Ip = 133.3amp [Corresponding coverage used = 11]Is = Transformer capacity / primary voltage = 1600/220Is = 7.27Amp [Correspondent coverage used = 20]DETERMINATION OF NUMBER OF TURN PER WINDING Np = Transformer ratio x ...

CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVECONCLUSION AND RECOMMENDATION 5.1 CONCLUSIONThe basic objective of the project that were realized include the guarantee of the supply during the absence power from service authority, the elimination of power surges and energy management induction of bill amazed from fuel cost and generator maintenance. The inverter is more environmentally friendly, easier to operate and required very little maintenance compared to a generator.Through the project is efficient and reliable, it has some limitation;i. It lacks transfers speed to automatically switch over during power outage.ii. ... Continue Reading
