3.1.7 REGULATOR
The regulator is a component with an internal standard voltage which it continually compares the actual output of the supply and makes appropriate adjustment by electronically controlling the resistor as connected in the circuit. The regulation is used because many electronic circuits imposed a varying load on their power supplies which will not function properly when the supply alters.
The regulator IC provide internal thermal overload protection and internal short circuit limiting. It has 3 terminals: input, ground and output. The voltage is specified by the last two digit of the IC part number. The regulator used in this inverter is IC7812 and it supply 12V D.C.
3.1.8 BATTERY
An electric battery is a device consisting of one or more electrochemical cell with external connection provide to power electric device. This is converted into 220volts AC supply at the inverter output socket.
3.1.9 SWITCHES AND SOCKET
ON/OFF and rest switches are commonly used in inverters. The reset switch is used to cut-off an overload circuits and restart the supply.

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 whe ... Continue reading---

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 i ... Continue reading---
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 aptitu ...
