I am considering the use of the UCC28513 due to the success one of my colleagues has had with it. However, I'm considering using the PFC in a SEPIC configuration as that naturally solves an inrush issue I have to deal with. Certainly there are more trade-offs when going from boost to SEPIC, but I was hoping to get a feel for how the controller would act in this configuration. SEPIC is notoriously difficult to hand-calculate the power train's gain/phase and modelling tends to be the most efficient way to find this / design for stability.
All that to say, any chance there is a PSPICE model for this part or perhaps something that is very similar?
