hello everyone, is there a method where I can get the bode plot of my dcdc boost converter without using the linear analyis tools of simulink and the plecs analysis tools as these last are not working for me. best regards

Share your model.

Hello Birdman, I would like to share my model with you. are you still here? I have just uploaded the model with the 03 methods to get the bode plot. 02 of them(AC sweep and Linear Analysis toos) shows a bode plot without DC gain(takes 1 days to finish the simulation) and the Impulse response Analysis does not work. as you can on the pictre uploaded of the result there is no DC gain wich wrong in my understanding because when I use the transfer function given by Pr. Christophe basso there is a DC gain as simulated in Matlab

Which figure you want to obtain?

I don't have plecslib_extras2 library. Can you share that with me as well?

the figure I want to obtain is the second one which has a DC gain,the first one is the one I get from the simulink model using the AC sweep from PLECS extra and linear analysis tools from simulink. I don't understand why I am not getting the DC gain,.SOrry I did not get your point from the second comment(I don't have plecslib_extras2 library.).do you mean the library?

the second figure I got it from the math transfer function of boost converter given by Pr.christophe basso and I have obtained its bode plot using Matlab in his book, so I thought the bode plot from the model Simulink and the math transfer function must match, but I can see some differences in shape and most important no DC gain in model Simulink
