someone working on z-source inverter

I being testing, for my z-source, its only stable up to 0.35 shoot through, so it might be pretty hard to reach from 48V to 350V dc. What have you managed to get as the gain?

Hi friends,

Can you share with me how you determine L and C for the Z network and design the output filter to get sine wave output? Thanks a lot

Hi Julio,

Thanks a lot for sharing your simulink with me. You use Vc for feedback. You put a gain of 0.66/526 right after the feedback Vc. How do you get this value? Thanks.

Hi, Julio can you shared with me the model of z-source for simulink matlab?

thanks in adnvance

hi julio,

can you shared with me model of z source inverter using PSIM... pls help me.....

hi,

I am working on my master level thesis. Any one help me for simulate z source inverter and guidance of design L & C value for Z - network.

Do you have any documentation regarding this simulation. TQ

hi....
I am trying z source inverter in PSIM... but output voltage has no boost up... i am confuse about switching sequence.... pls any one help....

help understanding the mdel

hey julioreye,
I was studying simulink model of z source inverter posted by you.i need some help regarding that model.I want to know why is there a peak capacitor voltage before it settles?i really need to know this so do reply plz.thanks.

hey budiyanto,
i am also looking for the answer of the same question that you asked.so if your doubt is cleared please share it with me.thanks

:lol:i also need that please

hi
is anyone working on quasi z source inverter? I need help to design a pi contoller to control modulatio index ratio. refering to paper " quasi z-source inveter for photovoltaic system connected to single phase AC grid"?

Regards
Adnan

Hello.

I am to build design and test a single phase 3kW inverter for a fuel cell, and I intend on using a Z-source inverter. I have just started this for my individual project and need all the sources I can get, so if anyone on here knows any good sources please send them to me.

I have choosen the Z-source as I wont need a DCDC converter this way. I need to build a model in MATLAB SIMULINK so the one on here should prove most useful. I have to have ideally a unity power factor also.

I got some experience on Z-source inverter. we built it for solar energy, single phase. we find it low efficiency and a little hard to soft start. actually we need a low real load for soft start or the output will climb very high...

hi julioreye

i just starting study on z-source inverter. do you have any experience using the PWM generator block? how to allocate a correct pulse to the correct gate if i'm using individual IGBT/diode block to develop the 3phase inverter?

in the help matlab document did mention that pulse 1, 3, 5 for the upper switches but when i try to allocate to the gate of IGBT/diode block the output seems not working properly.

thanks

hi friend. well i'm finishing my thesis too, although i made an implementation about the z source inverter. i have my report in spanish, if you want it i can give you. Currently i have some results about variables gotten from osciloscope.

CAn you send me your report or simulations programs, we just must to share our knowledge, bye.

Hi.
Would you please share with me how did u do the implementation part?
What was the power ratings for the ZSI you built? and what type of IGBT module u used? Thanks a lot

Hi Friends,

I K Anil Kumar from hyderabad. i was pursuing M-tech (power electronics)from 2009 still not yet completed.And my project is Comparison of Single-Phase Uninterruptible Power Supply Based on Z-Source Inverter with traditional UPS .first help me out how to design L and C values in Z-source inverter. plz Friends Looking forward to ur response.

Regards

Good Circuit . helped me lot to understand

Hello julioreye
thnks for posting the simulink part it is very helpfull,could you please send me how it works? if you have it, as i am doing MEng final year project please

Hi everyone I an currently working on z source inverter. Can anyone tell me what is the formula to calculate the value for capacitor and inductor for the impedance network.
