A magnetic integrated inductor according to an embodiment of the present invention is described below with reference to fig. 1 to 2, including an upper cover 1, a lower cover 2, a side column 3, and a center column 4;
the upper cover 1 is arranged above the lower cover 2;
the side columns 3 are arranged between the upper cover 1 and the lower cover 2 and are connected with the upper cover 1 and the lower cover 2;
a central pillar 4 is arranged between two adjacent side pillars 3, at least three central pillars 4 are arranged between the upper cover 1 and the lower cover 2, each central pillar 4 is connected with the upper cover 1 and the lower cover 2, wherein the number of the central pillars 4 is one more than that of the side pillars 3; each center pillar 4 is wound with a coil 12.
In the magnetic integrated inductor, the upper cover 1, the lower cover 2 and the two adjacent side pillars 3 can form an outer frame surrounding the center pillars 4, so that the magnetic fluxes in all the center pillars 4 can circulate in the paths formed by the upper cover 1, the lower cover 2 and the two adjacent side pillars 3, and between the two adjacent side pillars 3, a center pillar 4 is present, and the center pillar 4 is equivalent to a common magnetic path of the magnetic fluxes of the two adjacent side pillars 3, so that the magnetic fluxes of the center pillars 4 between the two adjacent side pillars 3 can be mutually offset, thereby reducing the magnetic core loss; between two adjacent center pillars 4, there is one side pillar 3, and the side pillar 3 corresponds to a common magnetic path of the magnetic fluxes of the two adjacent center pillars 4, so that the magnetic fluxes in the side pillars 3 between the two adjacent center pillars 4 can be offset with each other, thereby reducing the core loss. In addition, the volume of the magnetic core is reduced by sharing the center pillar 4 and the side pillars 3, thereby greatly reducing the product volume.
In some embodiments, the magnetic integrated inductor includes four side pillars 3 and three central pillars 4, and the four side pillars 3 and the three central pillars 4 are alternately distributed between the upper cover 1 and the lower cover 2, so as to form a three-phase seven-pillar structure.
As shown in fig. 1 and 2, the three center pillars 4 correspond to three phases of the power system one-to-one, and the four side pillars 3 and the three center pillars 4 are added up to form seven pillars in total, thereby forming a three-phase seven-pillar structure, which can be applied to a three-phase structure of the power system.
It is noted that the side pillars 3 and the center pillar 4 are parallel to each other.
As shown in fig. 2, the arrow direction is a direction of magnetic flux. In the left-to-right direction, the first side pillar 3 and the first center pillar 4 form a first magnetic path 6, the first center pillar 4 and the second side pillar 3 form a second magnetic path 7, the second side pillar 3 and the second center pillar 4 form a third magnetic path 8, the second center pillar 4 and the third side pillar 3 form a fourth magnetic path 9, the third side pillar 3 and the third center pillar 4 form a fifth magnetic path 10, and the third center pillar 4 and the fourth side pillar 3 form a sixth magnetic path 11, so that the directions of the magnetic fluxes flowing through the side pillars 3 are consistent, and the directions of the magnetic fluxes flowing through the center pillars 4 are consistent.
Optionally, a gap 5 is formed between the side column 3 and the center column 4. The provision of the gap 5 facilitates the winding of a large number of coils 12 around the center pillar 4.
Specifically, the width of each of the gaps 5 in the left-right direction is equal, and the length of each of the gaps 5 in the up-down direction is equal. The density of the coil 12 wound around the center pillar 4 is ensured to be equal everywhere, thereby ensuring that the density of the formed magnetic flux is also equal everywhere.
Preferably, the upper cover 1, the lower cover 2, the side pillars 3 and the center pillar 4 are integrally formed. The integrally formed structure can form a smooth magnetic path and reduce the magnetic resistance.
In some embodiments, the material of the side posts 3 is amorphous material and the material of the central post 4 is amorphous material. The side columns 3 and the middle columns 4 made of amorphous materials have low iron loss and coercive force, so that no-load loss can be further reduced, and the efficiency is improved. In addition, the amorphous material has high saturation and high magnetic induction intensity, and the same electrical performance can be achieved by smaller volume, which means that the volume of the magnetic integrated inductor can be further reduced.
