Title:
INTEGRATED INDUCTOR, CIRCUIT BOARD ASSEMBLY AND INVERTER
Document Type and Number:
WIPO Patent Application WO/2024/012155
Kind Code:
A1
Abstract:
The present application provides an integrated inductor, a circuit board assembly and an inverter. The integrated inductor comprises a first magnetic core, at least two second magnetic cores and at least two windings, the first magnetic core comprising a first surface and a second surface which are opposite one another in a first direction, and the first magnetic core being provided with a first through hole penetrating through the first surface and the second surface. The second magnetic cores are arranged on a side of the first surface distant from the second surface in the first direction, and the second magnetic cores are provided with second through holes. The windings are wound around the first magnetic core and the second magnetic cores, the windings and the first magnetic core forming a common mode inductor, and the windings and the second magnetic cores forming differential mode inductors. A second magnetic core comprises a first part and a second part, the first part being located between the winding and the first surface in the first direction and on the side of the first surface distant from the second surface, and the second part being located on a side of the winding distant from the first surface. The first magnetic core and a second magnetic core share one set of windings, which can save area occupied by the integrated inductor during installation while ensuring the working efficiency of the integrated inductor.
