Abstract
Multilevel inverters are the backbone of the industrial world in this age of technological revolution. It finds its application in several fields including medium voltage high power drives, integration of distributed generation and power utility applications in flexible AC transmission to name a few. Cascaded multilevel inverters (MI) stand out among all other MI for being the pioneer in MI technology and for being the forerunner in the practical application till date. Hence this paper represents 5-level and 11-level cascaded inverter’s simulation using sinusoidal pulse width modulation technique in MATLAB. Compare total harmonic distortion [THD] of 5-level and 11-level cascaded inverter’s phase voltage and line-to-line voltage.
