| Popis: | This paper summarizes geometrical effects on inductor winding loss based on a fixed diameter method and core gap effects. Relevant DC winding resistance equations of different winding configurations are derived and an effective inductor design method is given to the ratio of alternating to direct current $\displaystyle \frac{\triangle I}{I_{av}}$ =k 1 and ratio of skin depth to wire radius $\displaystyle \frac{\delta}{r}$. The core gap effect on the ac winding resistance can be minimized by increasing the distance far away from the gap, however the DC winding resistance will increase. The optimal distance between centre leg of a ferrite core and inductor winding, h, results in the minimum total winding resistance, which is validated by test and ANSYS FEM modelling. |
