Hi all,
I want to simulate a Flyback and a Forward converter. I've been trying, but there is a convergence problem in PSpice. I need the simulation to be quite long (1 sec or more) so all the transitory effects are stinguished. I've simulated a Buck and Buck-Boost and had no problem at all. I'm also a little lost finding a model for the transformer. I'd like to take the magnetization inductance, the turns and if possible the resistance into account. And the forward to have 3 wings.
Also, the voltage controlled switch I'm using doesn't seem a very elegant solution to me, is there any cleaner way to do it? Screenshots of the circuits I'm simulating:
Flyback:

(ignore the error, I just touched something right before taking the screenshot)
Forward:

(that only has 2 wings, but I just wanted to make the simulation work well)
What I'm trying to simulate are these models:

If you know any site that provides similar examples or maybe one with converter schematics files it would be appreciated, I tried Googling but found nothing.
Thanks in advance.
