Abstract

This paper summarizes geometrical effects on power inductor winding losses based on 4 different winding configurations (concentrically cylindrical, disc-typed, constant, and variable wire diameter methods). Relevant DC winding resistance for 4 winding configurations are derived. An effective inductor design method is given by considering the ratio of k (k = Iav/ _∆I), the ratio of skin depth to wire diameter 2τ/δ for fixed and variable wire diameter cases as well as a ratio of skin depth to the winding thickness (t/δ) for concentrically cylindrical and disc-typed winding cases. The core gap effect on the AC winding loss can be optimized by smart selection of the ratio of h/lg.
