PSpice model for Outputtranformers

[Posthorn]

I need help for these topics:

1.) How can I use the transformer TX_1 (included in the
evaluation Version of PSpice) to simulate a SE transformer ?

2.) What is in Norman Koren's PAT model the right way to connect
the two secondary windings ?

3.) Where can i get other transformer models

Tried it, never got it to work well enough, use Korens model.

The second secondary is the cathode feedback coil, check plitrons website for details on how to use it.

You make them yourself. Simply measure primary inductance, leakage inductance, primary capacitance and winding DCR (or estimate from datasheet) and enter into the model. Voila. A Transformer.
