Abstract
The utility model discloses a combined type induction transformer iron core which comprises an upper iron yoke, a lower iron yoke and intermediate columns. The upper iron yoke is matched with the lower iron yoke, and the intermediate columns are arranged between the upper iron yoke and the lower yoke. Through the method, the combined type induction transformer iron core can reduce magnetic core losses, and improve the efficiency of an inductor and a transformer.
Description
Technical field
The utility model relates to the transformer core technical field, particularly relates to a kind of compound inductive transformer iron core.
Background technology
In prior art, in the 1kHz-100kHz frequency range, the soft magnetic material iron core scope that high-power inductance can be selected is little, the FERRITE CORE size is too little, and the loss of silicon steel sheet magnetic core is larger, and the size of powder core magnetic core is little, permeability is low, loss is also larger, when using block amorphous state or ultracrystallite magnetic core, the air gap of magnetic core is concentrated, and causes near the leakage magnetic field of air gap larger, and the loss of inductance increases.
The utility model content
The technical problem that the utility model mainly solves is to provide a kind of compound inductive transformer iron core, can reduce core loss, improves the efficient of inductance, transformer.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of compound inductive transformer iron core is provided, comprise: upper yoke, lower yoke and intermediolateral column, described upper yoke and lower yoke are complementary, and described intermediolateral column is arranged between upper yoke and lower yoke.Upper yoke described in the utility model and lower yoke are complementary, and the shape that refers to described upper yoke and lower yoke is identical, area equates.
In preferred embodiment of the utility model, the material of described intermediolateral column is reguline metal ferrocart core, Fe-Si-Al magnetic core, iron silica magnetic particle core, high magnetic flux HF powder core or molybdenum perm MPP powder core.
In preferred embodiment of the utility model, the material of described upper yoke and lower yoke is amorphous material or ultracrystallite material.
In preferred embodiment of the utility model, being shaped as of described upper yoke and lower yoke is U-shaped, a kind of in C type or ellipse.
The utility model has also improved another technical scheme: the utility model also provides an inductor, described inductor comprises described compound inductive transformer iron core, the magnetic core that described inductor uses comprises: upper yoke, lower yoke and intermediolateral column, described upper yoke and lower yoke are complementary, and described intermediolateral column is arranged between upper yoke and lower yoke.
The utility model has also improved another technical scheme: the utility model also provides a transformer, and described transformer comprises described compound inductive transformer iron core.The magnetic core that described transformer uses comprises: upper yoke, lower yoke and intermediolateral column, and described upper yoke and lower yoke are complementary, and described intermediolateral column is arranged between upper yoke and lower yoke.
The beneficial effects of the utility model are: the compound inductive transformer iron core of the utility model can reduce core loss, improve the efficient of inductance, transformer, reduce the electromagnetic exposure of the upper and lower iron yoke part of iron core or concentrated air gap, reduce inductance value and increase the changing ratio that produces with magnetic field.

Fig. 1 is the structural representation of compound inductive transformer iron core one preferred embodiment of the utility model;
Fig. 2 is the structural representation of another preferred embodiment of the compound inductive transformer iron core of the utility model;
In accompanying drawing, the mark of each parts is as follows: 1, upper yoke; 2, lower yoke; 3, intermediolateral column.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection range of the present utility model is made more explicit defining.
See also Fig. 1, the utility model embodiment comprises: a kind of compound inductive transformer iron core comprises: upper yoke 1, lower yoke 2 and intermediolateral column 3, and upper yoke 1 is complementary with lower yoke 2, both shapes are identical and area equal, and intermediolateral column 3 is arranged between upper yoke 1 and lower yoke 2.
Furtherly, the material of described intermediolateral column adopts a kind of in reguline metal ferrocart core, Fe-Si-Al magnetic core, iron silica magnetic particle core, high magnetic flux HF powder core or molybdenum perm MPP powder core; The material of described upper yoke 1 and lower yoke 2 is amorphous material or ultracrystallite material, and wherein upper yoke 1 and lower yoke 2 is shaped as U-shaped, C type, ellipse or other shapes.
It is less that compound its upper yoke of inductive transformer iron core of the utility model, lower yoke are that amorphous alloy or ultracrystallite material have reduced the loss of magnetic core, intermediolateral column has used the reguline metal powder core, reduced due near the leakage magnetic field the concentrated air gap that air gap causes of use, the loss of inductance reduces.
The core structure of the compound inductive transformer iron core of the utility model is applied in inductor, the core structure of inductor comprises: upper yoke, lower yoke and intermediolateral column, described upper yoke is complementary with lower yoke and both shapes are identical, area equates, described intermediolateral column is arranged between upper yoke and lower yoke.
The core structure of the compound inductive transformer iron core of the utility model is applied in transformer, the core structure of transformer comprises: upper yoke, lower yoke and intermediolateral column, described upper yoke is complementary with lower yoke and both shapes are identical, area equates, described intermediolateral column is arranged between upper yoke and lower yoke.
See also Fig. 2, be another kind of embodiment of the present utility model, upper yoke 1 and lower yoke 2 be shaped as ellipse.
The above is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
