Abstract
The utility model relates to a two-phase direct-current uncoupled integrated inductor which comprises an iron core, inductive windings and magnetic barriers, wherein the iron core is of an up-down structure formed by overlying silicon steel sheet laminations. The two-phase inductive windings are laid on magnetic cylinders on the two sides of the iron core respectively, and the two magnetic barriers are arranged in the up-down structure of the iron core and located over the two-phase inductive windings. Anti-saturation air gaps of the structure of the iron core are used as the magnetic barriers at the same time, numerical values of the magnetic barriers are reasonably selected, flux linkages generated by the inductive windings are isolated, and decoupling of inductors of the same iron core is achieved. Accordingly, the problems that the number of magnetic cores and the size are large when two independent inductors are used as a single magnetic core to be wound are solved. Compared with the two independent inductors, the two-phase direct-current uncoupled integrated inductor has the advantages of being small in size, light in weight and the like and can be widely applied in the future.

Technical field
The utility model relates to a kind of inductance, particularly the non-coupling integration inductor of a kind of two-phase direct current.
Background technology
In modern power electronics devices, usually need many independently DC inductances, for example multiple DC transfer circuit, needs a plurality of separate inductors.But when each inductance carrys out coiling with independent magnetic core, magnetic core quantity is more, equipment volume is strengthened.And multiphase DC integrated inductor is with respect to a plurality of separate inductors, there is volume little, the lightweight supremacy clause that waits, will be used widely.
As everyone knows, can circulate by non-magnetic media in magnetic field, causes magnetic circuit decoupling zero and isolation ratio circuit relative complex.So the heterogeneous non-coupling direct current integrated inductor of direct current has certain technical advantage.This heterogeneous non-coupling direct current integrated inductor, adopts unique design, utilizes the anti-saturation magnetic resistance of DC inductance, and two discrete inductance are integrated in to an iron core.Formed heterogeneous non-coupling direct current integrated inductor.
Realize two inductance integrated, require on same magnetic core array, to there are many magnetic branch roads, and separate between magnetic circuit, can not there is magnetic coupling.That is to say, the magnetic linkage of an inductor winding generation can not be by other inductor winding coexisting on an iron core.Two discrete magnetic fluxs could be formed to a plurality of inductance like this realizes on an iron core.
Summary of the invention
The utility model is for using in a plurality of separate inductor equipment, inductance causes equipment volume large, the problem that equipment is heavy, the non-coupling integration inductor of a kind of two-phase direct current has been proposed, core structure anti-saturation air gap is hindered as magnetic simultaneously, choose reasonable magnetic barrier numerical value, the magnetic linkage that two inductor windings are produced isolation, has realized the decoupling zero between two inductance of same iron core.For direct current power translation circuit, provide miniaturization integrated inductive device.
The technical solution of the utility model is: the non-coupling integration inductor of a kind of two-phase direct current, comprise that lamination is overrided to form the iron core of up-down structure, inductor winding and magnetic barrier, two-phase inductor winding is laid in respectively on the magnetic post of iron core both sides, in iron core up-down structure, respectively have magnetic barrier, two magnetic barriers be positioned at two-phase inductor winding directly over.
Described magnetic barrier is comprised of nonmagnetic substance.
Described iron core is for to be overrided to form by UT shape lamination, and a slice U-shaped and a slice T shape lamination form one deck UT shape lamination, and T shape lamination inserts in U-shaped lamination.
Described iron core is that LLT shape lamination is overrided to form, and two L shaped laminations and a slice T shape lamination build up one deck LLT shape lamination, and two L shaped lamination symmetries are positioned at T shape lamination below.
The beneficial effects of the utility model are: the non-coupling integration inductor of the utility model two-phase direct current, and when by two, independently inductance carrys out coiling with independent magnetic core, magnetic core quantity is many, and volume is larger.Adopt the non-coupling direct current of two-phase integrated inductor, reduce core volume, reduce equipment volume and weight, greatly reduce equipment cost simultaneously.
