The coil structure, power factor correction circuit including the coil structure, and power supply including the power factor correction circuit

Abstract

The term "shield" refers to a coil structure comprising an inductor with a linked coil wire structure and including a central hole, a detection coil electrically coupled to the inductor, a support unit surrounding at least part of the outer outer edge of the inductor, and a housing consisting of an upper and lower magnetic body facing each other vertically with the inductor in the middle to form an internal space in which the inductor and detection coil are arranged, each upper and lower magnetic body including a small part inserted into the central hole of the inductor.
