Abstract

The invention relates to an interleaved magnetic integration type coupling inductor, consisting of an E-Chinese character 'Wang'-I-shaped core body and a coil, wherein the E-Chinese character 'Wang'-I-shaped core body consists of a Chinese character 'Wang'-shaped core, an E-shaped core and an I-shaped core; the E-shaped core and the I-shaped core are arranged at the both sides of the Chinese character 'Wang'-shaped core in the middle of the core body; two-phase coils are respectively wound on two middle posts of the Chinese character 'Wang'-shaped core; three magnetic path air gaps are arranged at contact positions of one sides of three transverse yokes of the Chinese character 'Wang'-shaped core and three transverse yokes of the E-shaped core; and other three magnetic path air gaps are arranged at contact positions of the other sides of the three transverse yokes of the Chinese character 'Wang'-shaped core and the I-shaped core. The interleaved magnetic integration type coupling inductor provided by the invention has the beneficial effects in that the coupling inductor is used for inductive coupling integration; the quantity of the air gaps is increased for one time; the length of the air gaps is reduced for a half; the diffusion flux of the air gaps can be obviously reduced; energy and materials can be saved; and the electromagnetic interference is reduced.

Description

technical field [0001] The invention relates to an inductor, in particular to an interleaved parallel magnetic integrated coupling inductor, which can be widely used in various interleaved parallel switching power supplies with single-phase operation and bidirectional operation. technical background [0002] In recent years, switching power supplies that provide electrical energy for various electrical equipment are developing in the direction of low voltage, high current, small size, light weight, high efficiency, thinning and integration, including the widely used in electric vehicles that have emerged in recent years , hybrid vehicles, uninterruptible power supplies, power quality regulation power supplies, aviation power supplies, renewable energy power generation and superconducting energy storage and other bidirectional switching power supplies that require bidirectional energy flow. These switching power supplies use a multi-phase interleaved parallel topology. It can...
