Abstract
An integrated inductor comprises a first winding (C) and a second winding (C); a first internal magnetic core in the first winding (C) and a second internal magnetic core in the second winding (C); and at least one external magnetic core (M) outside the first winding (C) and the second winding (C), used for being connected to end portions of the first and second internal magnetic cores to form a magnetic path, the external magnetic core (M) being formed by multiple sub-magnetic cores joint with each other; the magnetic conductivity of at least one sub-magnetic core of the multiple sub-magnetic cores is greater than the magnetic conductivity of other sub-magnetic cores, and the at least one sub-magnetic core at least covers a part of end faces of the first internal magnetic core and the second internal magnetic core. The integrated inductor can alleviate the phenomenon of flux leakage, and can reduce costs of the magnetic cores.
