The multilevel inverter utilization has been increased since the last decade. These new types of inverters are suitable in various high voltage & high-power application due to their ability to synthesize waveforms with better harmonic spectrum and faithful output. This paper presents a comparison of nine-level cascaded H-bridge multilevel inverter with five-level cascaded H-bridge multilevel inverter. Multicarrier phase-shifted pulse-width modulation method is used to achieve balanced power distribution among the power cells. The analysis of the output voltage harmonics is carried out. From the results, the nine-level cascaded H-bridge multilevel inverter provides higher output quality with relatively lower power loss as compared to the five-level cascaded H bridge multilevel inverter with the same output quality.
