Background technology
Inducer is the element that electric energy can be converted into magnetic energy and be stored.Inducer is similar to that transformation
Device, but only one of which winding.Inducer has certain inductance, and it only hinders the change of electric current.If inducer is without electricity
In the state of stream passes through, it will attempt to hinder electric current to flow through it during circuit ON；If inducer is in the state for having electric current to pass through
Under, it will attempt to maintain electric current constant when circuit disconnects.Inducer is also known as choke, reactor, dynamic reactor.Inductance can be by
Conducting material wound around magnetic cores are made, typical such as copper cash, also magnetic core can be removed or be replaced with ferrimagnet.Than air
The high core material of pcrmeability more closely can constrain in magnetic field around inductance element, thus increase inductance.Inductance has very
It is various, made with outer layer enamel coil encircling ferrite bobbin mostly, and some protection inductance are completely disposed at ferrite coil
It is interior.The core of some inductance elements can be adjusted.It is possible thereby to change inductance size.But existing PFC inductor products poor performance,
Magnetic energy loss is big, affects the use of inductance.
Utility model content
The purpose of this utility model is to provide a kind of high magnetic permeability PFC inductance, possesses low excellent of good product performance, magnetic loss
Point, solves the problems, such as that existing PFC inductor products poor performance, magnetic energy are lost the impact inductance such as big and use.
For achieving the above object, this utility model provides following technical scheme：A kind of high magnetic permeability PFC inductance, its feature
It is that the inductance includes firm banking, becket is fixedly connected with the top of the firm banking, becket is provided with fin, institute
The inside for stating becket is fixedly connected with magnetic core, and the magnetic core is by Fe based Microcrystalline Alloy magnetic powder material layer, permalloy magnetic powder material

The bottom of seat is fixedly connected with connect base, and the bottom of the connect base is fixedly connected with pin.
Preferably, the quantity of the pin is eight, is divided to upper and lower two rows parallel equidistant to arrange, after uplink and downlink pin serial connection
Electrically connect with the left connecting line of coil and the right connecting line of coil respectively.
Compared with prior art, the beneficial effects of the utility model are as follows：
This utility model is by Fe based Microcrystalline Alloy magnetic powder material layer, permalloy magnetic powder material layer and cobalt-based by magnetic core
Non-crystaline amorphous metal magnetic powder material layer is composited, and has the advantages that high saturation magnetic strength, high initial magnetoconductivity and magnetic loss are low, by setting
Becket is put, the thermal diffusivity and stability of PFC inductance is improve, the low advantage of good product performance, magnetic loss has been reached.Magnetic core is combined
The advantage of various materials, can be very good suppression common mode noise, filter EMI harmonic waves, absorb the spike that Switching Power Supply is produced, and keep away
Exempt from surge voltage and damage device, reduce circuit size, improve the stability and reliability of system.It is existing so as to effectively solve
PFC inductor product poor performances, the big problem for affecting inductance to use of magnetic energy loss.
