Abstract
The utility model discloses an improved inductor which comprises two U-shaped magnetic cores and coils. Openings of the two U-shaped magnetic cores are in butt joint, the coils are wound on columns of the two U-shaped magnetic cores, air gaps capable of strengthening magnetic saturation are disposed on the columns of the magnetic cores, and epoxy glue filled layers are arranged in the air gaps. The improved inductor has the advantages that the air gaps are added into a magnetic circuit, magnetic saturation capacity is improved, accordingly, the inductor is low in loss and high in energy storage, the epoxy glue filled layers are disposed in the air gaps, and a radiating performance is good.
Description
Technical field
The utility model relates to a kind of inductor, particularly relates to a kind of rectifier that is applied to HF switch.
Background technology
In existing P FC inductance, adopt EI, EE, PQ, H type magnetic core mostly, because inductance value can not be linear change with current strength, so can't realize the Digital Control of PFC.Saturated in order to prevent, generally on existing magnetic core, increase an air gap, there is an air gap in two butted U-shaped magnetic cores at joint; But have only an air gap, loss is big, and energy storage is few; Be difficult to satisfy needs high-power, high-frequency Switching Power Supply, and radiating effect is also bad.
Summary of the invention
The utility model technical problem to be solved is, provides that a kind of loss is little, energy storage big, the inductor of perfect heat-dissipating.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of improved inductor; Comprise two with mode butted U-shaped magnetic core mouth to mouth be wrapped in two coils on the U type core post; It is characterized in that: the lateral surfaces of said core post is provided with the air gap that strengthens the magnetic saturation ability, is provided with the epoxy glue packed layer in the said air gap.
Aforesaid a kind of improved inductor is characterized in that: the material of described U type magnetic core is a ferrite.
Aforesaid a kind of improved inductor is characterized in that: described air gap evenly distributes on the lateral surfaces of core post.
Compared with prior art, the utility model has the advantages that, in magnetic circuit, increased air gap, improved the magnetic saturation ability, make that the inductor loss is little, energy storage is big, and be provided with epoxy glue packed layer, perfect heat-dissipating in the air gap.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
For further disclosing the technical scheme of the utility model; Now be described with reference to the accompanying drawings the execution mode of the utility model: as shown in Figure 1; A kind of improved inductor; Comprise two with mode butted U-shaped magnetic core mouth to mouth 1 be wrapped in two coils 2 on the U type core post, the material of U type magnetic core 1 is a ferrite.The lateral surfaces of core post is provided with the air gap 3 that strengthens the magnetic saturation ability, and air gap 3 evenly distributes on the lateral surfaces of core post, is provided with the epoxy glue packed layer in the air gap 3.
During manufacturing, on the lateral cross section of two U type core post, cut out certain air gap 3, fill epoxy glue then in the cut place, be beneficial to heat radiation with emery grinding wheel.
More than, the basic design and the basic principle of the utility model have been set forth through introduction to listed execution mode.But the utility model never is limited to above-mentioned listed execution mode, and every equivalent variations, improvement of doing based on the technical scheme of the utility model reaches and deliberately become of inferior quality behavior, all should belong to the protection range of the utility model.
Claims (3)
1. improved inductor; Comprise two with mode butted U-shaped magnetic core mouth to mouth be wrapped in two coils on the U type core post; It is characterized in that: the lateral surfaces of said core post is provided with the air gap that strengthens the magnetic saturation ability, is provided with the epoxy glue packed layer in the said air gap.
2. a kind of improved inductor according to claim 1 is characterized in that: the material of described U type magnetic core is a ferrite.
