Coupled inductor

Abstract

A coupled inductor includes a magnetic structure, a first winding wire set, a second winding wire set, and an insulating oxide film set. The magnetic structure includes a magnetic core. The first winding wire set is disposed in the magnetic structure and wound outside the magnetic core. The second winding wire set is disposed in the magnetic structure and wound outside the magnetic core. The first winding wire set and the second winding wire set overlap and stagger with each other in a height direction of the magnetic structure. The insulating oxide film set is disposed between the first winding wire set and the second winding wire set to electrically isolate the first winding wire set and the second winding wire set.
