ABSTRACT

The design and construction of a 50HZ, 240V 1 kV A 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 subcircuits

to give optimum performances. The sub circuit include; the oscillator circuit, PWM

circuit, driver circuit, low battery/overload shutdown circuit, charging control/soft charging

circuit, surge protection circuit, changeover/power supply circuit, and the output circuit . The

focus is on designing an inexpensive, noiseless, no weather ( environmental) pollution and

efficient inverter that give a modified sine wave at the output. The project can as well be used to train students.
