Abstract
This paper presents an analysis and comparison of magnetics structures in a tapped boost converter for LED applications. The magnetic structure is a coupled inductor which is analyzed in a conventional wire-wound core as well as in a planar structure for different interleaving winding arrangements. The analysis is performed in terms of leakage inductance, winding capacitance and winding loss. Efficiency measurements are performed to verify the effect on the converter performance.
