This paper discusses a simulation configuration of three-phase multilevel diode-clamped inverter (DCI) employing Phase Disposition Pulse Width Modulation (PDPWM) with stepped wave as modulating signal. Three phase-three level inverters are simulated and PDPWM is used as the control method. The output waveforms of multilevel inverters are presented and comparison study between Sinusoidal Pulse Width Modulation (SPWM) and PDPWM is done. Total harmonic distortion of pole voltages are analyzed and compared. Analysis for over modulation condition is also simulated.
