Abstract

In this paper the AC winding resistance of the litz wire wound planar square coil is derived. The Biot-Savart’s law is used to derive analytical expression for the AC winding resistance. Analytical calculations are done for two planar square coils of different size. Experimental verification and comparison of the calculated and measured winding resistances are performed.
