Abstract

This paper summarizes the winding geometrical and core gap effects on inductor winding loss. Relevant DC and AC winding resistance equations are derived, and an optimal inductor design is given for the ratio of direct to ripple current ${\text{k}} = \frac{{{I_{av}}}}{{{{\Delta }}I}}$. A new concept of a curve-gapped inductor solution is proposed to improve the line harmonic current for lighting equipment.
