In the last decade, multilevel inverters have gained popularity in academics and business for maximum-power and level-voltage energy regulation. Due to lower switch ratings and lower total harmonic distortion (THD), their performance far outperforms that of traditional two-level inverters. Thus, while keeping the inverter output constant the multilevel method is used to eliminate harmonic distortions. They do, however, have several limitations, such as an increase in the components, a complicated PWM control system, and difficulty in the voltage balance. The research looks at multiple topologies of a Nine level inverter (NLI) based on criteria such as harmonic distortion (THD), circuit intricacy and the usage of power components and other components, all with DC voltage as input sources. The designs being investigated are DCMLI, FCMLI, CHBMLI and RSCHBMLI. For a nine-level inverter, these designs are simulated using MATLAB/Simulink. A PWM generator controls each switch on the NLI. The results are compared, presented and discussed.
