What is the impact or radial/axial current crowding on AC resistance of stacked foil windings in axially/radially wound transformers?
The orientation of the winding inside the transformer tends to not effect the magnetic (H) field. We use idealized fields to calculate leakage inductance. So basically, there isn’t any difference in a PC foil vs. a wound foil. Fringing does effect this, but so far its an intractable problem because there isn t enough geometrical data present and the complexities of the interaction of the windings, gap, and core.
