MAGNETIC INTEGRATED INDUCTOR

WIPO Patent Application WO/2015/106593

A1

The present invention relates to a magnetic integrated inductor comprising: two magnetic cores and two coils assembled vertically opposite. Each magnetic core comprises: a base plate, two first magnetic core columns arranged on the left and right sides on the base plate, and, two second magnetic core columns arranged at center positions on upper and lower sides on the base plate, where the base plate, the two first magnetic core columns, and the two second magnetic columns are integrally formed to constitute each magnetic core. When two magnetic cores are assembled vertically opposite, one or more first air gaps are provided between the first magnetic core columns arranged at a same side, and one or more second air gaps are provided between the second magnetic core columns arranged at a same side, where the sum of the lengths of the first air gaps of the magnetic cores is less than the sum of the lengths of the second air gaps. Two coils respectively are wound on the opposite first magnetic core columns on the left and right sides of the two magnetic cores to form left and right induction coils. When powered and excited while working, the two induction coils respectively generate magnetic fields that are directed in a same direction as the vertical alignment of the first magnetic core column being wound.
