A Method of Improving the Inductance Coefficient of Air Gap Magnetic Core

Abstract

The invention discloses a method for improving the inductance coefficient of an air gap magnetic core. The air gap magnetic core is formed by combining more than two magnetic cores. The combined surface which magnetic flow passes comprises lateral surfaces, the mirror surface process is adopted for the lateral surfaces, and accordingly the inductance coefficient of the whole magnetic core can reach above 80%. Well wound windings are arranged on the magnetic core in an interdigitation mode and then are baked at a high temperature or are electrified on two magnetic cores for fusion, and accordingly the inductance coefficient of the magnetic core can be further improved. After adopting the method, the volume of a transformer or an inductor which is made of the magnetic core is small, and the winding process of the transformer or the inductor is simple.

Description

technical field

[0001] The invention relates to a magnetic core, in particular to a method for increasing the inductance coefficient of an air gap magnetic core. Background technique

[0002] Magnetic core: A magnetic core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures. Magnetic cores have a wide range of uses. Since the 1980s, computer power supplies have fully realized switching power supplies, and they took the lead in completing the replacement of computer power supplies. In the 1990s, switching power supplies have successively entered the fields of various electronic and electrical equipment, program-controlled switches, Communications, electronic testing equipment power supplies, control equipment power supplies, etc. have widely used switching power supplies. In household appliances, such as color TVs, routers, and mobile phone charging, switching power supplies have been used for power supply. Rapid development.
