Hello,
I am having a persistent “Cyclic behavior during switching” error in my Quadratic Buck-Boost Converter simulation in PLECS, specifically when the duty cycle falls below 0.67. Above this value, the simulation runs perfectly and reaches steady-state.
I checked the solution on the Plexim website at What does the error message "cyclic behavior during switching" mean? | Plexim but I couldn’t find a solution for my case.
I have attached my .plecs file to this post. Thanks in advance.
