Title:
INDUCTOR AND POWER-SWITCHING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/223715
Kind Code:
A1
Abstract:
An inductor (10). The inductor comprises a first portion winding, a second portion winding, a magnetic core (12) and a winding, wherein the first portion winding is a conductive path (140) disposed on a circuit board (14), the second portion winding is a set of conductors (16) that are plugged into the circuit board, and the conductive path of the circuit board and the conductors plugged into the circuit board are mutually connected; and the inductor forms, by means of plugging-in between the conductors and the circuit board, a continuous conductive winding wound around the magnetic core. The inductor uses different types of conducting media to form, by means of combination, an inductor winding, so that during a manufacturing process, the action of repeatedly winding wires like single winding is not needed, and cutting and bonding a magnetic core during the manufacturing process are also not needed.
