Hi Radhakrishna,

Exactly what issue are your having?

When I run the file I immediately receive this error.

Then, I get this convergences problem.

Convergence problems can be resolved by adjusting the simulation accuracy parameters and/or setting a maximum time step (like 100ns).

Regards,

Eric

Hello,

As much as I'd like to help I'm not a transformer designer. There are numerous papers discussing transformer design for flybacks on the web. Is that from TINA? I could not find a multi-winding transformer model in the TINA library.

We're here to help with the application of our controllers.

Regards,

Eric
