Coyle and contactless power transmission for contactless power transmission

摘要

The stability of Coyle for contactless power transmission equipment is stabilized.Solution 1 for the contactless power transmission apparatus, the Coyle 1 comprises a winding 3 through which alternating current flows, a core 2 for forming a part of a circular magnetic path intersecting the winding 3, and a bobbin 4 wound around the winding axis o.The core 2 comprises a bottom 21, an inner core 22 which rises from the bottom 21 and is disposed inside the windings, and an outer core 23 which rises from the bottom 21 and is disposed outside the winding.End surfaces 22a and 23a are formed in the inner core 22 and the outer core 23, respectively.A first flange portion 42 extending in the radial direction of the winding shaft o is provided in the bobbin 4, and the first flange portion 42 is disposed so as to extend over the end surface 22a of the inner core and the end face 23a of the outer core.Diagram
