Abstract

The emerging multilevel inverters are superior to the two level inverters due to their improved modulation schemes, good power control, reduced device count, and their capability to handle various operational issues. This paper proposes an improved multilevel inverter topology which produces better results in the nine level output voltage waveform. The reduction in Total Harmonic Distortion (THD) is achieved by performing various experiments in the modulation strategies of the inverter. This serves as a major impact of the proposed work. The control methodology used for evaluating the performance of the inverter is variable frequency PWM strategy with disfigured carrier. The results were presented and compared.
