Abstract: The main purpose of this project is to design and verification of a 1000 Watts 220 Volts inverter at a frequency of 50Hz. The inverter is one of the most important and most important components in an independent energy system. It provides power supply when there is cut in government power supply. It plays very important role in areas where there is regular cuts in power supply. It works on the basic principal of charging and discharging of battery. This device is constructed with locally sourced components and materials of regulated standards. The basic principle of operation is a simple conversion of 12V DC into 220V AC from a battery using integrated circuits and semiconductors at a frequency of 50Hz, across the windings of a transformer. Our aim behind this project is to provide an additional power supply at and with the same power output.
