Optimum design of high current power planar inductors with flat winding Universiteit Gent
High current power planar inductor as a key component of high-power Switch Mode Power Supply (SMPS) is presented in the paper. The main advantages of the planar inductor over a conventional wire wound component are discussed. A design process including detailed fringing coefficients for different shape E and ER planar cores is introduced. FEM models with ANSYS®/Maxwell® are investigated, and the results are presented.
