Abstract

This paper proposes implementation of Two and Three Level Diode-Clamped Multilevel inverter using IGBT’s fed to both built -in and mathematical model of PMSM drive. The pulses for the inverters have been developed by using Space Vector Pulse Width Modulation Technique (SVPWM). Space Vector Pulse Width Modulation Technique is most prominent PWM technique for three phase voltage source inverters for the control of AC Induction Motors, Brushless DC Motors, Switched Reluctance and Permanent Magnet Synchronous Motors. The output voltages, currents, torque and speed characteristics have studied for two and three-level inverters fed to both mathematical model and built -in model. It has observed that both have same results. Three -level inverter can use more DC link voltage than two- level inverter and also SVPWM Technique utilizes DC bus voltagemore efficiently and generates less harmonics.
