Abstract：

Winding　loss　is　the　key　to　the　design　of　magnetic　components.　The　traditional　theoretical　method　for　calculating　the　high-frequency　eddy　current　loss　of　transformer　foils　is　the　Dowell　model.　With　the　increase　of　the　operating　frequency　of　the　power　converter,　the　influence　of　the　two-dimensional　(2-D)　edge　effect　on　the　winding　loss　gradually　increases,　but　the　one-dimensional　(1-D)　model　cannot　predict　this　phenomenon.　According　to　the　model　of　multi-conductors　in　parallel　to　form　a　foil　conductor,　this　paper　proposes　a　foil　winding　high-frequency　loss　model　that　can　accurately　predict　the　2-D　edge　effect.　And　the　accuracy　of　the　proposed　model　is　verified　by　finite　element　method　(FEM).　©　2021　IEEE.
