    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

    hi every body
    please help !!!
    I need simulation of Z_source with PWM
    nobody have this!!!

    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.[​IMG]

    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?
