  • Magnetic component and power transfer device
    Patent number: 9672974
    Abstract: A magnetic component includes a first winding and a second winding which is insulated from the first winding and magnetically couples with the first winding. The first winding forms a first coil unit by being wound. The second winding forms a second coil unit by being wound about the same axis as the first winding. The second winding forming the second coil unit is disposed in areas X and Z. The magnetic component has the first coil unit and the second coil unit at positions that satisfy Equations 1 and 3.
