| Abstract |
This article presents a method for reducing AC resistance in planar transformer windings by using a new type of cut-winding structure. The proposed winding modification aims at improving the current density distribution in the winding's area, by increasing the resistance of the eddy current's loop and organizing the proximity effects between primary and secondary interleaved layers. A physical prototype with the modified windings has been implemented on a 2 kVA planar transformer and compared with common planar windings. 2D FEA simulations has been used to investigate the proposed technique. Empirical measurements on the physical prototypes shows that the modified cut-windings present a 45\% lower AC resistance under full load. |
