Abstract
The locally constructed inverter in this paper has the rating of 1kva and 220V AC output. Requirement for the implementation include locally sourced 100AH 12V deep cycle battery, IC SG3524 oscillator, MOSFET’S and BJT types of transistors, transformer, diodes, resistor, contactor, relay, capacitor and other electronic components. The stages comprise of oscillator unit, MOSFET assembly unit, Transformer unit and battery charge unit. Each constructed unit was independently tested for accurate functionality before the composite was coupled. The inverter in an electronic device converts DC supply to AC. The input is 12VDC and the output is 220V modified sine wave. The waveform and the output stability parameters of these two inverters were compared and the result shows that the locally constructed inverter has a better performance and cost effective than the branded one.
