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

Hi,

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

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

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

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

3.) Where can i get other transformer models

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.
