Title:
AN INTEGRATED INDUCTOR AND A METHOD FOR REDUCTION OF LOSSES IN AN INTEGRATED INDUCTOR
Document Type and Number:
WIPO Patent Application WO/2012/126993
Kind Code:
A3
Abstract:
An integrated inductor comprising a multi-winding inductor having a transformer winding (L1) and a resonant inductor (L2). Sections (1), (2) of the magnetic circuit of the transformer winding (L1) are incorporated into magnetic circuits of at least two parts (L2A), (L2B) of a resonant inductor (L2) so as to form common parts of magnetic circuit of the multi-winding inductor (L1) and at least two-part (L2A), (L2B) resonant inductor (L2), wherein the transformer winding (L1) of the multi-winding inductor is wound around a column (11), which has at least one air gap (G) having a width adapted so that the magnetic induction produced by the at least two-part (L2A), (L2B) resonant inductor (L2) does not exceed 25% of the magnetic induction produced by the transformer winding (L1) of the multiwinding inductor.
