Title:
VERTICAL MULTIPHASE INDUCTOR AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/122953
Kind Code:
A1
Abstract:
The present application discloses a vertical multiphase inductor and a manufacturing method therefor. The vertical multiphase inductor comprises a magnetic body, a plurality of first coils, and a plurality of second coils. The plurality of first coils and the plurality of second coils are arranged in the magnetic body at intervals in a layered manner in a second direction. A second coil is arranged between every two adjacent first coils in the second direction. The orthographic projection of the first coils falls into the orthographic projection of the second coils. According to the present application, a plurality of inductors can be integrated into one single multi-phase inductor, and the consistency of electrical parameters such as the inductance value L, RDC, and coupling coefficient K of the multi-phase inductor is high. A high electrical performance consistency can maintain signal stability in a working circuit, and the space of a PCB circuit to be occupied can be reduced.
