摘要：
Dual inverter fed open end winding induction motor (IM) drive offers many advantages over other multilevel inverter fed IM drives. Pulse width modulation (PWM) techniques are employed for the control of output voltage and frequency. Space vector base PWM techniques are popular among all the PWM techniques. A simplified space vector PWM method with simple and small look-up table approach is presented for dual inverter configuration. Moreover the proposed space vector based PWM technique provides freedom in selecting the center voltage vector (CVV) by which different PWM techniques will be derived. The implementation of all these PWM techniques is generalized by using a constant ao. The derived PWM techniques show superior performance in reducing the zero sequence voltage (ZSV) by maintaining the same quality of output voltage. The performance of all these PWM techniques are evaluated theoretically and verified in real time through dSPACE 1104 control board. © 2019 IEEE. All rights reserved.
