The design and construction of a 50HZ, 240V 0.5kVA inverter is primarily based on an inverter circuit which inverts the D.C. source voltage from a battery, AC voltage for AC powered appliances. The overall operation of this system comprises inter connections of many sub-circuits to give optimum performances. The sub circuit include the PWM circuit, driver circuit, input transformer circuit, input side rectifier circuit, feedback opto-coupler circuit, and the output circuit (MOSFET and transformer section). The purpose of this project is to design and construct a 300Watts (0.3KW) 220 Volts Inverter at a frequency of 50Hz. This device is constructed with locally sourced components and materials of regulated standards. The basic principle of its operation is a simple conversion of 12V DC from a battery using integrated circuits and semiconductors at a frequency of 50Hz, to a 220V AC across the windings of a transformer.
