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 ]The capacitance is thus, the number of coulumbs stored per unit voltage across the capacitor i.e.C= Where C is the capacitance in farads Q is the charge in coulumb V is the voltage across the capacitor in voltsFig 3..2 capacitor 3.1.3 DIODE A diode is a semi-conductor device which allow flowing of current in one direction. Diode is a device which can be either forward or reversed biased. It has a low resistance and is unidirectional. Diodes are various types such as a rectifier diode, turning diode, zener diode, light emitting diode (LED) and ph ... Continue Reading
CHAPTER FOUR - [ Total Page(s): 5 ]Ns = 3520/12=293 turnsTherefore Es = 240vNs/Np = Es/EpNs = (Np Es)/EpNs = 240 x 16 12Ns = 3840 = 320 turns 124.1.3 FREQUENCY DIVISION COUNTER This unit is made up of integrated circuit, it serve as a counter to divide the 100Hz signal generated into two equal part i.e 50Hz (Nigeria Standard), these divided frequency of 50Hz each is in the anti-phase and therefore are each alternating fed to the base of the MOSFET in the inverting stage.4.1.4 FREQUENCY UNIT The purpose of this project is to remove all harmonic i.e distortion from the modified sine-wave so that the output could be ...

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
