Hello,
The first thing I noticed is that your model in its current form does not run do to an error message “cyclic behavior during switching”. To better understand what this means, I recommend you see our website post on the topic: What does the error message "cyclic behavior during switching" mean? | Plexim. I was able to get your model running simply by increasing the “Diode turn-on threshold” solver setting from 0 to 1e-3. The small-signal analysis tools should then be able to converge. Note that for your model, you might consider the Impulse Response Analysis tool for a much faster result. I attached a plot capture below showing the results I saw when using this. Regarding the settings you emboldened above, did you review our documentation about what they do? I hope this helps!
Regards,
Kris
