Abstract
This paper presents the results of investigations on a planar sandwich air-gapped transformer with two different winding configurations. Experimental results of the coil self inductances, voltage ratio versus frequency, and the numerical results for the magnetic flux and eddy-current distributions are presented. It is shown that the voltage ratio and turns ratio are not equivalent and that the voltage ratio is frequency dependent
