with refrence to this suggestion a newer version of same model has been uploaded,however this model will proove to be helpful to students in learning the basic concept of z source inverter.

where is the feedback circuit?

even the paper presented in IEEE can be said a partially successful one. It shows a large overshoot in voltage(ie speed of motor) in < 1 second. The motor can't withstand this speed.

you have not included shoot through state pulses.This model is not an Z-source inverter, because of the absence of shoot through pulses. The impedenze network is correct.Without shoot through stste, it works as a SPWM inverter.
Shoot through pulses can't be generated along with the SPWM signals. It has to be generated seperately and added to the SPWM whenever it is necessary to boost the output voltage.The need for shoot through pulse is only when speed of motor falls below set speed. So a feedback system is needed to sense the speed and it has to be coupled with the shoot through pulse generator.
In this model there is no feed back circuit and speed comparator. In fact a PID controller is enough to do it. It will be better if we use microprocessor. There is no information about the THD also.
Needs a lot of more additions. I am trying to do it.
