a wire wound inductor of a switched-mode power supply and switched-mode power supply with the wire-wound inductor

摘要

The present invention represents a wire-wound inductor of a switched-mode power supply and a switched-mode power supply with the wire-wound inductor ready. Of the wire-wound inductor has a magnetic core and a winding which is wound on the magnetic core, on. A buffering pad, between the magnetic core arranged and the winding. Of the wire-wound inductor, which is provided by means of the present invention, is connected to the buffering pad between the magnetic core and the winding is provided in order for the dimensionally changes of the magnetic core, which, by means of the magnetostriction phenomenon, are caused to absorb and thus, the relative positions of the components is maintained. The collision between the magnetic core and the winding can be prevented, and then the noise is reduced.
