hi,
I am having problems designing a ferrite core for my SMPS.It does not give the desired results. The circuit works fine with ideal transformer model but the moment I introduce this core it gives absurd results. I need imformation on how to extract parameters while feeding in the B-H curve values from the datasheets as I have observed that it makes a lot of difference if I change the order of extraction with the same points.also there is no PACK parametre for a ferrite core so what am I supposed to do with that.
I think I have stated the problem explicitly,hope somebody can help.
regards
anshul
