Dual inverter fed open end winding induction motor(IM)drive offers many advantages over other multilevel inverter fed IM *** width modulation(PWM)techniques are employed for the control of output voltage and *** 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 *** the proposed space vector based PWM technique provides freedom in selecting the center voltage vector(CVV)by which different PWM techniques will be *** implementation of all these PWM techniques is generalized by using a constant *** derived PWM techniques show superior performance in reducing the zero sequence voltage(ZSV)by maintaining the same quality of output *** performance of all these PWM techniques are evaluated theoretically and verified in real time through dSPACE 1104 control board.
