Abstract

The utility model relates to a power factor correction (PFC) inductor for an energy-saving power supply, which is characterized by comprising a first U-shaped iron core, a second U-shaped iron core, a first inductor coil and a second inductor coil. The first U-shaped iron core and the second U-shaped iron core are in butt joint through end surfaces of respective extending arms and accordingly form a rectangular structure, and the first inductor coil and the second inductor coil are respectively installed on two butt joint portions between the first U-shaped iron core and the second U-shaped iron core. The iron cores of the PFC inductor are changed from annular shapes to rectangular shapes so that the iron cores can be filled in after the coils are well wound, and winding is more convenient due to the fact that winding is changed from manual winding to automatic winding.

Description

A kind of PFC inductance that is used for energy-saving electric power
Technical field
The utility model relates to a kind of PFC (Power Factor Correction, power factor correction) inductance that is used for energy-saving electric power.
Background technology
PFC (Power Factor Correction) i.e. " power factor correction " mainly is used for characterizing the utilization ratio of electronic product to electric energy.Power factor is high more, explains that the utilization ratio of electric energy is high more.Through the computer power of CCC authentication, all must increase pfc circuit.The position is after second layer filtering, before the full bridge rectifier.
PFC has two kinds, and a kind of is passive PFC (also claiming passive PFC), and a kind of is active PFC (also symmetrical active PFC).Passive PFC adopts generally the inductance compensation method to make to exchange that phase difference reduces to improve power factor between fundamental current and the voltage of input, but the power factor of passive PFC is not very high, can only reach 0.7-0.8; Active PFC is made up of inductance capacitance and electronic devices and components, and volume is little, can reach very high power factor, but cost to exceed passive PFC some.
The wire winding of traditional P FC inductance is till directly from first to last once backbone winding being expired with stranded wire mostly.Its shortcoming and defect part is:
1), winding ratio is difficult; 2), temperature rise, radiating effect is poor; 3), can only on lower wattage power supply, use.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming of prior art, and a kind of PFC inductance that is used for energy-saving electric power is provided, and can effectively improve winding efficiency.
For solving above technical problem; The utility model technical scheme is: a kind of PFC inductance that is used for energy-saving electric power; Its difference is: it comprises a U sections core, the 2nd U sections core, first inductance coil, second inductance coil; Thereby both dock a U sections core, the 2nd U sections core each other through the end face of cantilever arm separately and constitute rectangular configuration, and first inductance coil, second inductance coil are installed in two docking sections between a U sections core, the 2nd U sections core respectively.
By above scheme, also comprise can, a U sections core, the 2nd U sections core, first inductance coil, second inductance coil all are arranged in the can.
The contrast prior art, the beneficial features of the utility model is following:
1), iron core changes rectangle into by annular, reinstalls iron core after can winding coil earlier like this, coiling changes the automatic coil winding machine coiling into by artificial coiling, it is convenient to wind the line.
2), inductance coil is the double wrap coil structures that is made up of first inductance coil and second inductance coil, thereby has better radiating effect.
3), this is used for the PFC inductance of energy-saving electric power, increases can, is convenient to produce and install and use, and reduces the electromagnetism interference of PFC inductance to other components and parts in the power supply.
Description of drawings
Fig. 1 is used for the PFC inductance example structure sketch map of energy-saving electric power for the utility model.
Fig. 2 is used for the PFC inductance overall structure sketch map of energy-saving electric power for the utility model.
Wherein: 1-the one U sections core, 2-the 2nd U sections core, 3-first inductance coil, 4-second inductance coil, 5-can.
Embodiment
Combine accompanying drawing that the utility model embodiment is done further explain through embodiment below.
Please refer to Fig. 1; A kind of PFC inductance that is used for energy-saving electric power of the utility model embodiment; It comprises a U sections core 1, the 2nd U sections core 2, first inductance coil 3, second inductance coil 4; Thereby both dock a U sections core 1, the 2nd U sections core 2 each other through the end face of cantilever arm separately and constitute rectangular configuration, and first inductance coil 3, second inductance coil 4 are installed in two docking sections between a U sections core 1, the 2nd U sections core 2 respectively.
Concrete, comprise that also can 5, the one U sections cores 1, the 2nd U sections core 2, first inductance coil 3, second inductance coil 4 all are arranged in the can 5.Can 5 can armoured magnetic field, reduces the electromagnetism interference of PFC inductance to other components and parts.Simultaneously, can 5 bodies relatively also more easy mounting in energy-saving electric power.
Iron core changes rectangle into by annular and is made up of two parts (a U sections core 1 and the 2nd U sections core 2), reinstalls iron core after can winding coil earlier like this, and coiling changes the automatic coil winding machine coiling into by artificial coiling, and it is convenient to wind the line; Machine coiling can increase line footpath can be used on more powerful power supply.
Inductance coil by the multiply fine copper wire and around, can reduce the coiling difficulty, and effectively reduce the high-frequency current temperature rise; The double wrap circle that inductance coil is made up of first inductance coil 3 and second inductance coil 4, thus better radiating effect had.
Concrete, the PFC inductance uses the heat-conducting glue embedding, and effective heat conduction also reduces temperature rise, can also be moistureproof, grease proofing, be adapted at using under any adverse circumstances.
Above content is the further explain that combines concrete execution mode that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection range of the utility model.
