which software you are used? you can use Orcad/Pspice to analysis this full-bridge boost converter and you can get an efficient and accurate results so close to the practical one.

I used MATLAB simulink, I also attached my mdl file of my project,

Dear Omid,

Unfortunately, I cannot check your SIMULINK file now but I recommend you verify it by PROTEUS results. It is much better than SIMULINK in power electronic circuit analyses.

Moreover, ORCAD is another possible option too. Try it!

Mr Omid,

I checked your simulation, What you simulated seems to be wrong. Actually for your simulation, the output you must get is 110V, but you are getting 55V for duty cycle of 0.5. Please check all gate pulses to the switches in your ckt. they are wrong. You are not allowing the inductor to charge by shorting all the switches. Thats why you are not getting boost operation. So please give pulses to the switches as mentioned in "Fundamentals of Power Electronics" text book by Ericson.

I found my problem, my problem was duty-cycle settings.

Thanks a lot,

I use Psim Sofware to simulate Power converter (free demo version).

this software is simple to use (i use it in simulations lessons with my students)

You can use MATLAB Simulink or PSIM software student version.
