Abstract :
In high performance AC drive systems, the large power three-level voltage source inverters equipped with IGCTs are widely used now and have promising future. In this paper, the principle of space vector PWM (SVPWM) for three-level inverter is introduced. Some problems of SVPWM for three-level inverter are discussed. Based on the system simulation, a high power three-level inverter equipped with IGCTs is designed. The working performance of the inverter is verified with system experiment. The experiment results show that the inverter has excellent performance
