Title:
EMI COMMON-MODE INDUCTOR OF NEW WINDING METHOD AND WINDING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/001402
Kind Code:
A1
Abstract:
The embodiments of the present invention disclose an EMI common-mode inductor of a new winding method and a winding method for the EMI common-mode inductor, relating to the technical field of common-mode inductors. The EMI common-mode inductor of the new winding method comprises a toroidal magnetic core, and wound at symmetric positions on two sides of the toroidal magnetic core, two windings and four lead ends. Each winding is a multi-segment winding, and multiple layers are wound around each segment of a winding. Two lead ends of each winding are disposed at two ends of the winding respectively, and one of the lead ends is positioned at the innermost layer of the winding and the other lead end is positioned at the outermost layer of the winding. The embodiments of the present invention can ensure EMI effect, realize automatic winding, effectively improve production efficiency, greatly save labor, lower reject ratio, reduce product cost, and achieve win-win between a client and a supplier.
