Abstract

The invention relates to an inductor. The inductor comprises a magnetic core and a winding which comprises a first part winding and a second part winding, wherein the first part winding is a conductive path arranged on a circuit board, the second part winding is a group of electric conductors connected with the circuit board in a plug-in mode, the conductive path of the circuit is connected with the conductors connected with the circuit board in a plug-in mode, and the inductor forms continuous conducting winding which winds around the magnetic core through plug-in between the electric conductors and the circuit board. The inductor uses different types of conducting media which are combined to form the inductor winding, in the manufacturing process, the action of repeatedly winding wires like single winding is not needed, and the process of cutting and bonding the magnetic core in the manufacturing process is not needed.

Description

technical field [0001] Embodiments of the present invention relate to the circuit field, and more specifically, relate to an inductor and a power conversion circuit. Background technique [0002] In integrated circuits or power supply circuits in various electronic devices at present, integrated inductors or inductive components are widely used, and use their own magnetic induction characteristics to act on current and voltage in the circuit. The basic components of a common inductor are a magnetic core and a winding, typically a metal conductive wire wound around the perimeter of the core. At present, such wire-wound inductors are manufactured by inductor manufacturers using magnetic cores, enameled wires, and glue auxiliary materials. The manufacturing process involves repeated winding of metal conductive wires around the magnetic core, which is cumbersome and time-consuming. Contents of the invention [0003] The embodiment of the present invention provides an inductor...
