摘要
This paper presents an estimation of high-frequency winding resistance and power loss in individual inductor layers made of foil, taking into account the skin and proximity effects. Approximated equations for power loss in each layer are given and the optimal values of foil thickness for each layer are derived. It is shown that the winding resistance of individual layers significantly increases with the operating frequency and the layer number, counting from the center of an inductor. The winding resistance of each foil layer exhibits a minimum value at an optimal layer thickness. The total winding resistance increases with the total number of layers.
