Dear Prathusah, the theory on the boosting factor in Z source inverter is available in the literature. please refer to the paper...

this paper defined the control of the boost control and very simple and interesting explanation of this. may be this will be helpful to understand. If still find difficulty in making the simulation model plz mail me on [email protected]. I have the simulink model for this.

regards

Thankyou so much for the answer sir

with regards

Boosting factor can be considered as the ratio of the peak of the output phase voltage divided by half of the DC input voltage of the Z-Network.
