Description
Technical field
This utility model relates to a kind of inductance element, especially relates to a kind of convertible frequency air-conditioner high frequency PFC inductance.
Background technology
Electronic component in working order time, be i.e. an electromagnetic interference object, be again an interference source.Electromagnetic interference is permissible
It is divided into two classes: series mode interference and common mode disturbances.The series mode interference function of current between two signal line, its conduction orientation and waveform and
Signal code is consistent, and common-mode interference current acts between signal line and ground wire, and interference electric current respectively flows in two signal line
Cross 1/2nd and in the same direction, and with ground wire as common return.If common mode current filters without decay, then common-mode interference current
Just it is easy to produce electromagnetic radiation.U.S. FCC, the CISPR22 and the GB9254 of China of international wireless electrical interference special commission
Etc. standard criterion, all the common mode Conduction Interference of Information Technology Equipment and radiation are had relevant restriction.Traditional PFC inductance core one
As use the ferrite production of low cost, but its saturation induction density is low, adjusting range is narrow, and temperature stability is poor, limits
The range of application of PFC inductance.Further, existing PFC inductance can only use in low-power, additionally, direct current biasing characteristic is general,
The serviceability causing PFC inductance declines.
Summary of the invention
This utility model purpose is to provide a kind of convertible frequency air-conditioner high frequency PFC inductance, to solve the saturated magnetic of existing common mode inductance
The technical problems such as induction is low, adjusting range is narrow, temperature stability is poor, range of application is restricted.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of convertible frequency air-conditioner high frequency PFC electricity
Sense, including base, described base bottom is provided with pin, base is provided with the magnetic core ring of circle, it is characterized in that described magnetic core ring
Including being positioned at the inner insulating layer of internal ring, outside inner insulating layer, it is arranged with Fe-based amorphous alloy core layer, Fe-based amorphous alloy core layer
Being arranged with outward super ferrum aluminum silicon powder last layer, be arranged with screen layer outside super ferrum aluminum silicon powder last layer, screen layer is externally provided with external insulation layer；
Being symmetrically wound on two sides with some circle inductance coils at magnetic core ring, the end of inductance coil is connected with the pin on base.
As preferably, described magnetic core ring holding is on PBT base.
As preferably, described Fe-based amorphous alloy core layer is the loop configuration turned to by Fe-based amorphous nanometer band.
This utility model has that size is little, iron loss is little, pcrmeability is high, inductance is high, temperature stability is good, anti-DC-bias
The advantages such as saturability is excellent, production cost is low.Its inductance coil uses sub-thread coiling, effectively reduces coiling difficulty.Inductor wire
Circle uses butterfly to have mercy on method, effectively reduces electric capacity between coil, reduces product temperature rise.Use at the bottom of flame-retardant PBT between inductance coil and PCB
Seat isolation, effectively prevents coil and PCB contact short circuit.This product can push away on a large scale in high-tech sectors such as convertible frequency air-conditioners
Wide application.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model；
Fig. 2 is structural representation of the present utility model；
Fig. 3 is the left view of structure shown in Fig. 1；
