Improved Analysis and Modelling of Leakage Inductance for Planar Transformers [PDF]

, 2018
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
