Abstract
The utility model provides a power inductance, the utility model discloses a power inductance of improvement electric current. The utility model provides a following technical scheme: the utility model provides a power inductance, the inductance including magnetic core, coil and permanent magnet, the magnetic core be the I shape magnetic core, including first horizontal part, second horizontal part and connection the vertical part of first horizontal part and second horizontal part, the coil winding be in vertical part, the permanent magnet inlay respectively and locate the diameter range of the magnetic core vertical part on first horizontal part and the second horizontal part, the magnetic field that produces when the magnetic field that produces and inductance circular telegram opposite direction. The beneficial effects of the utility model reside in that: when the inductor is electrified, the direction of an induced magnetic field generated by the inductor is opposite to that of a magnetic field of the permanent magnet, so that the internal magnetic field is reduced, the anti-magnetic saturation capacity of the inductor is improved, and the saturation current of the inductor is increased.
Description
Technical Field
The utility model discloses a power inductance, especially a power inductance who improves electric current.
Background
At present, in the common winding power inductor in the market, the current passing through the inductor is influenced by the magnetic field generated by the inductor, so that the inductor with the increased current is necessary in many application scenes.
SUMMERY OF THE UTILITY MODEL
This solve the above-mentioned problem, the utility model provides a following technical scheme:
the utility model provides a power inductance, the inductance including magnetic core, coil and permanent magnet, the magnetic core be the I shape magnetic core, including first horizontal part, second horizontal part and connection the vertical part of first horizontal part and second horizontal part, the coil winding be in vertical part, the permanent magnet inlay respectively and locate the diameter range of the magnetic core vertical part on first horizontal part and the second horizontal part, the magnetic field that produces when the magnetic field that produces and inductance circular telegram opposite direction.
Furthermore, the lead pin of the coil is led out from the first transverse part direction.
The beneficial effects of the utility model reside in that: when the inductor is electrified, the direction of an induced magnetic field generated by the inductor is opposite to that of a magnetic field of the permanent magnet, so that the internal magnetic field is reduced, the anti-magnetic saturation capacity of the inductor is improved, and the saturation current of the inductor is increased.
Drawings
FIG. 1 is an exploded view of the present invention;
fig. 2 is a simplified overall schematic diagram of the present invention.
Detailed Description
The invention will be further explained and explained with reference to the drawings.
Referring to fig. 1 and 2, the power inductor comprises a magnetic core (1), a coil (2) and a permanent magnet (3), wherein the magnetic core is an i-shaped magnetic core and comprises a first transverse part (11), a second transverse part (12) and a vertical part (13) connected with the first transverse part (11) and the second transverse part (12), the coil (2) is wound on the vertical part (13), the permanent magnet (3) is respectively embedded in the diameter range of the magnetic core vertical part (13) on the first transverse part (11) and the second transverse part (12), and the magnetic field generated by the permanent magnet (3) is opposite to the magnetic field generated by the inductor when the inductor is electrified. The permanent magnet (3) material includes but not limited to neodymium iron boron, ferrite. The magnetic core (1) can be soft magnet, and the soft magnet is formed by pressing metal powder particles, such as alloy powder, carbonyl iron powder, reduced iron powder and organic curing agent which are fully stirred and mixed. The current direction of the inductor is preferably kept uniform.
Furthermore, the lead-out pin of the coil (2) is led out from the direction of the first transverse part (11).
