hi
please help me to simulation of Z-source inverter with PWM in MATLAB or PSCAD

question:
how produce and control the signal of switching in shoot-throogh-state

Fig 11 show switching signal in traditional inverter.
Fig 12 show switching signal in Z-source inverter. in Z-source inverter the switches of one leg, can turn on in the same time (shoot-throogh zero state) . with control time of shoot-throogh zero state, we can step up or down the DC link voltage. Now, we make switching signal for Z-source inverter from switching signal in the Fig 11 and we attention to PWM control
Excuse me about my bad writing.
Thanks a lot.

Perhaps if you show what you have accomplished so far, someone might be able to help. Few here are motivated to do your homework for you.

I understand the concept of Z-source inverter, but i can produce signal in shoot through zero state in the Matlab or PSCAD.
In the Matlab or PSCAD, we can not shift the signal in negative time.
Do you know Z-source inverter perfect?
