A magnetic device includes a winding, and insulators by which the winding is surrounded. Each of the insulators is in contact with the winding. A gap exists between each two adjacent of the insulators in a winding direction of the winding.

Magnetic device including winding and insulators, and power conversion device using the same

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.
