Abstract

Recently, almost all industrial devices are mostly built on electronic devices which are precisely sensitive to harmonic. In order to meet the requirement from the industries demand aimed at a free-harmonics and high power rating source is remarkably increased in past few years. An inverter which a device or electric circuit that convert direct current to alternating current is one of the electronic devices that give concern to researchers for improvement of generating a neat power source. The inverter can be categorized into a single level and multilevel inverter. As compared to single level inverter, multilevel inverter offers minimum harmonic distortion and higher power output. This paper presents a model of multilevel inverter using 7-level Cascaded H-Bridge of multilevel DC-AC inverter to reduce total harmonic distortion with different sinusoidal pulse width modulation such as phase disposition and phase opposition disposition. Simulation output of single phase multilevel inverter cascaded H-bridge are analysed and verified in the Matlab/Simulink software. The result show that the 7-level cascaded H-Bridge multilevel inverter with phase disposition technique generate less total harmonic distortion if it is compared to the phase opposition disposition technique.
