    Hello! I was working on my simulation for a buck boost converter. Here are the specs I originally assumed

    Vg=24
    Vo=48
    Io=1A
    delta Il=100ma
    It worked on the ideal case, but when I tried implementing real transistors to the buck boost model, I get different results

    Can anyone give some advice on what I did wrong with my model?

    Can't suggest anything without knowing the difference between the simulation results and the real circuit results.
