Abstract:
Planar transformers have often been mistaken to essentially have lower leakage inductances. The “radial effect” is a nature characteristic for planar windings due to a higher aspect ratio of conductor width to conductor thickness, which gives a reduction of leakage inductance. Traditional formulas of leakage inductance calculation for traditional transformers where the winding width is much smaller than the winding height, b<
