Investigation of Current Sharing in Paralleled Winding at High Frequency Transformers

Automatized connection of the layers of planar transformers with parallel windings to improve the component behavior

“…Some default interleaving is assigned before optimization to improve the coupling among windings: primary layers occupy positions 3,4,7,8,11, and 12, and secondary layers are 1,2, 5,6, 9, 10, 13, and 14.…”

“…The high frequency behavior of the magnetic component depends on many effects that must be evaluated to get an appropriate design: the working frequency, the geometry of the windings, their connections, and their loads. This problem has been studied before [1][2][3][4][5]. In [1] a gapped transformer for a LLC resonant converter is designed, but this work lacks of a systematic search of windings connections.…”

Selection of the appropriate winding setup in planar inductors with parallel windings

“…There are some works where the analysis of these components design is covered [1][2][3]. However, the goal of this paper is to describe the problem of designing planar inductors with parallel windings and to provide a methodology to select the appropriate winding setup in order to optimize the current sharing.…”
