Thank you, Sheldon!
The transformer model should be correct (the capacitance has been measured between primary and secondary side). Due to the trifilar winding, the interwinding capacitance should be very low. Furthermore, I have omitted the resistances as the impact on simulation results is quite low.
But indeed, your simulation results look like my measurements. The differences in your simulation results are quite low compared to my simulation results. Up to now, I have not been able to measure the interwinding capacitance as I did not find any resonance frequency. These capacitance seems to be the key for a successful simulation.
Hence, I will take a closer look at the transformer model. Wish, it would be easier to get all these transformer's parasites.
What stays is, that I will feel quite unconfident about simulation results when simulating circuits with large inductances and I will check all integration methods and errpresets.
Many thanks, Joerg
