Etc. technological deficiencies, be unfavorable for the reduction of reduction and the loss of core volume.
Summary of the invention
It is an object of the invention to overcome above-mentioned technical deficiency, provide it is a kind of it is easy to implement, iron core coupled structure is simple, magnetic
Road air gap and coil length are minimum, save copper material, the magnetic that coil copper loss and core loss are small integrates coupling inductor.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of integrated coupling inductor of " mesh " font magnetic, is made of " mesh " font iron-core workpiece and two-phase coil, described " mesh "
Font iron-core workpiece is made of four "U" shaped iron cores；The magnetic pole of the two of them "U" shaped iron core is staggered relatively and forms
" mouth " font iron core, four magnetic poles of the two of them "U" shaped iron core are two-by-two with respect to " mouth " font iron core described in composition
Two magnetic poles；Two phase coils described in coiling are distinguished in described two magnetic poles of " mouth " the font iron core；It is described other two
"U" shaped iron core is respectively placed in the magnetic pole two sides of described " mouth " font iron core, is buckled on two phase coil, it is described other two
The magnetic pole two sides of the magnetic pole of "U" shaped iron core and " mouth " the font iron core keep a distance and form air gap.
The beneficial effects of the present invention are:
1. the inductance that the present invention both can be used for the crisscross parallel Switching Power Supply of traditional unidirectional operation is integrated, can be used for
The inductance of the crisscross parallel Switching Power Supply of the way traffic of rising in recent years is integrated, to realize the integrated, small of Switching Power Supply
Type, planarization and high efficiency.
2. air gap quantity of the invention is doubled than the air gap quantity of traditional " EE " or " EI " type coupling inductor, and every
The length of a magnetic air gap reduces half, so the magnetic pressure distribution of magnetic circuit is more uniform, the dispersing flux of magnetic air gap significantly subtracts
Small, the electromagnetic consumable as caused by dispersing flux and electromagnetic interference are substantially reduced, not only can be energy saving, but also can increase iron core
Inductance coefficent saves copper material to reduce coil turn.
3. iron-core workpiece of the invention is composed of conventional "U" shaped iron core, large-scale production easy to accomplish.
4. the present invention replaces the method for grinding iron core to adjust gas length using the method for gasket, hold that gas length more
Easily adjustment.
5. the present invention can first around making coil, the magnetic pole of two "U" shaped iron cores is passed through into coil and dock and
" mouth " font iron core is formed, other two "U" shaped iron core is buckled on two phase coils, simple production process, it is easy to accomplish big
Scale automated production.
6. the mutual inductance magnetic circuit of two coils is most short, magnetic resistance is minimum, and coupling is most close, to increase from inductance value and coupled systemes
Number, and reduce coil turn, save copper material.
It is elaborated below in conjunction with attached drawing with embodiment.
