Abstract
In this paper, a decoupled Space Vector Pulse Width Modulation (SVPWM) technique for indirect vector controlled induction motor drive in open end winding configuration is presented. The decoupled space vector PWM technique provides independent control of each inverter in an Open End Winding Induction Motor (OEWIM) drive. With this advantage, failure of any one inverter in the drive can be operated with reduced output voltage. With the freedom in selecting different voltage vectors for each inverter, this decoupled PWM technique also reduces the Common Mode Voltage (CMV), when compared with other coupled PWM techniques. Within a sample time T , in conventional s continuous decoupled space vector PWM technique, each inverter is operated with zero voltage vectors and active voltage vectors. In this paper to reduce the CMV with good quality of output voltage inverters with different continuous and discontinuous PWM (DPWM) techniques were presented. Within a sample time T , these PWM techniques use active s vectors, but zero voltage vectors may be replaced by new active vectors or zero vectors which are unequally shared. The performance of these PWM techniques were analyzed in MatLab/Simulink and the results were presented.
