ABSTRACT

In this paper, an inverter system of 1KVA Power is designed from transformation ratio equations and relay configuration and on to electronic components and devices
that converts DC Supply from Battery to AC Supply suitable for household and office appliance to cater for instability in power supply. The AC supply given out has a relatively smooth Sine Wave required for normal operation of any appliance. The Inverter is designed to operate for a minimum of thirty (34)
minutes, which depends on the ampere hour rating of battery used in the inverter. The charged battery of the 1KVA inverter is capable of maintaining the continuity and quality of electric power supply in a living home with a battery charger using a square wave oscillation, power MOSFET switching circuits and
two lead acidic 60AH batteries. The results of the analysis of the inverter interface are attached as appendix.
