Design and develop an inverter for solar PV system

Abstract

This project is to design an inverter circuit that will produce a 230 VAC square wave with a power rating of 200 Watt and will be used in solar photovoltaic (PV) system. Conceptually, an inverter is an electrical device that convert direct current (DC) to alternating current (AC) where the resulting AC can be at any required voltage and frequency with the use of appropriate transformer, switching and control circuits. A 12 VDC battery will be used as a voltage source of this project and then will be inverted to a 230 VAC square wave output. The method in which the low voltage DC power is inverted to a desired output is complete by convert the low voltage DC power to AC power with an appropriate switching technique and then a transformer is used to step up the voltage to 230 VAC. For a continuously operation of this inverter circuit, a solar panel will be used to recharge the battery.
