Abstract

This paper presents an an alysis 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 term s of leakage inductance, winding capacitance and winding loss. Efficiency measurements are performed to verify the effect on the converter performance
