TINA/Spice/TINA-TI: Non-linear transformer magnetizing inductance TINA

Lukasz Huchel

Part Number: TINA-TI

Tool/software: TINA-TI or Spice Models

Hi,

I would like to use a model of a flyback transformer in my simulation. It looks like using non-linear model is a good way to define turns ratio, winding resistance and magnetizing inductance. My question is how can I add new core type to make sure that the equivalent magnetizing inductance is what I need (at the operating point)? Or maybe there are models that I can directly set a constant value of magnetizing inductance plus turns ratio?

Thanks

Hi,

I have seen this thread. I was asking if there is any way to use non-ideal transformer (with finite magnetizing inductance) but linear, where Lm and all parameters are fixed. I am trying to model it as below with magnetizing inductance Lm and ideal transformer but maybe there is other way.
