Hello everyone,

I am desiging a SMPS with a push pull and I would like to simulate it with a more-real transformer model.

I have found this model, which includes several parasitics (forget the given values):



The figure works with a transformer with a primary and a secondary winding. How would it be the magnetizing inductance in a a Push Pull converter?
What do you think about this model:


particularly, What do you think about the leakage (just one) and the magnetizing (two of them, one for each primary) inductances?

As always, I would be very thankful if you can help me.

David.
