Abstract

A dc-ac converter is a circuit that converts the dc voltage supply to an ac voltage output and this converter also known as inverter. Inverter is used in many types of industrial and commercial applications especially in dc–ac conversion, ac motor drives, system controls and Uninterruptible Power Supply (UPS). This project combines the knowledge of electrical and electronic. The objective of this project is to design Quasi Square Wave Inverter that supply 240 Vac which controlled by four switches of MOSFET (Metal Oxide Semiconductor Field Effect Transistor). The MOSFETs also are controlled by gate drive circuits. The project is started with simulation of inverter circuit by using OrCad software to get the waveform of output and switching of MOSFET. The hardware circuit is then constructed and the output waveforms are shown by oscilloscope. This project will include operation, analysis, control strategy and experimental result based on the software and hardware implementation.
