The phase disposition pulse width modulation (PDPWM) based Reduced Switch Reverse Voltage (RSRV) multi level inverter is investigated and analysed in this chapter. This inverter has a smaller number of components than others. The amplitude and frequency modulation index values are examined in relation to improving output power quality using PDPWM. This PDPWM-based 9-level inverter produces a superior harmonic spectrum due to decreased components and an odd-valued frequency modulation index value. All of the lower order harmonics are well within the IEEE-519 standard's limits. To validate its operation, a simulation model of a PDPWM-based asymmetrical 9-level inverter with a decreased number of components is created, and the results are reported. When used for a larger number of output levels, this inverter requires fewer components.
