Reply To: Leakage inductance realization in transformer

[Tamami Yamanaka]

Hello,

If you see asymmetrical inductance, it could be due to several factors, including the physical geometry of the windings or the presence of the air gap you've introduced. It's important to first make sure that the actual physical layout in the windings, core, and air gaps matches the intended symmetrical design. Second, check that the mesh around the air gaps is fine enough. You can also simplify the design by removing the air gap and simulating with only one primary and one secondary winding, and then gradually add complexity back in to see where the asymmetry occurs.
