This paper proposes implementation of Three Level Diode-Clamped Multilevel inverter using IGBT's fed PMSM drive. The pulses for the inverters have been developed by using Carrier based Space Vector Pulse Width Modulation Technique (CB-SVPWM). Carrier based Space Vector Pulse Width Modulation Technique is most prominent PWM technique for three phase voltage source inverters for the control of Permanent Magnet Synchronous Motors. The output voltages, currents, torque & speed characteristics have studied for three-level inverters fed PMSM drive. It has observed three -level inverter with Carrier based Space Vector Pulse Width Modulation Technique (CB-SVPWM) can use more DC link voltage as compare to Space Vector Pulse Width Modulation Technique (SVPWM). And also CB-SVPWM Technique utilizes DC bus voltage more efficiently and generates less harmonics.
