A Nine-Level Diode Clamped Inverter with Sinusoidal PWM technique is presented in this paper. Three Phase inverter is studied and simulated in MATLAB/SIMULNK. In this paper the inverter is controled with the Level Shifted scheme of Sinusoidal PWM i.e. Phase Diosposition (PD), Phase Opposition Displacement (POD) and Alternative Phase Opposition Displacement (APOD). The inverter is simulated for R-L load and THD for output waveforms is observed for differnt controlling schemes. The THD for the output waveforms is observed and the the technique with least THD is seleted for furhter simulations
