Title:
VOLTAGE TRANSFORMATION METHOD, ELECTRONIC DEVICE, AND PLANAR TRANSFORMER AND WINDING STRUCTURE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/087484
Kind Code:
A1
Abstract:
Provided in the present application are a voltage transformation method, an electronic device, and a planar transformer and a winding structure thereof. A first winding and a second winding of the planar transformer are arranged in a cavity of a magnetic core, and a first coil of N turns of the first winding is arranged on the upper and lower sides and left and right sides of a second coil of M turns of the second winding, so that when a current flowing through the first winding and a current flowing through the second winding are flowing in opposite directions, the magnetic fields of the first coil and the second coil can cancel each other out, thereby reducing the magnetic field strength of the first winding and the second winding in multiple directions in the planar transformer, and thus reducing eddy current loss in the planar transformer.
