Design And Construction Of A DC To AC Inverter System

Abstract

This project is titled the design and construction of a DC to AC inverter system. It is designed to meet up with the power demand in the offices and in homes in the absence of power supply from the national supply authority, NEPA. In order words the device / item serves as a substitute for NEPA which almost monopolises the power supply to people.
It is designed in such a way that it will take up 12v DC from battery and inverts it to an output of 220v, 50H2 AC. It makes no noise during operation and no hazardous carbon monoxide is generated in the surrounding.
This is a feature that makes it safe to use any were when compared to generator. Also, the circuit is capable of charging the battery (i.e 12v source) when the power from the supply authority is on. This greatly reduces the cost of operation of the system.

1.0 INTRODUCTION
The idea behind the design and construction of this system is to make available or alternative means of power supply for household or industrial purpose. This goes a long way in helping to curb the problem frequently encountered as a result of power failure. That not with standing it makes it possible to have other means of providing power our doorstep rather than solely depending on the power from he national grid.
Moreover, rate of power failure in this wantry is high. So there is every need that other means of power supply should be made available for constant running of our electronic equipments and gadgets and also to provide comfort to man. Hence, with the help of a DC to AC inverter system, which has come to solve the problem of frequent power failure of Nigeria, a steady running and operation of our electronic equipments and gadgets is guaranteed.

1.2 INVERTER SYSTEM
The inverter system was built to convert a DC voltage to an AC voltage with the help of oscillator
This inverter system also consists of two stages of switching circuits which comprises of power transistors connected in the common drain configuration.
Since the oscillator has two outputs. Each of the switching circuit is coupled to the two output of the oscillator respectively. This is well explained in detail in chapter three below.
When the oscillator is powered from the 12v DC battery, the oscillator of the system generates 60 which is then used to open the gate of the transistors which has specific power and current ratings.
The combined output power and current of the transistors will then be applied to the transformer which then steps up the voltage to an output level of 220V AC.
