Abstract
The present invention relates to a kind of inductor group, more particularly to a kind of inductor to pass through the inductor group of the composite magnetic circuit of the yoke portion composition of common magnet, and this inductor group is in power electronics energy conversion system, belonging to inductor structure design field.Present invention seek to address that inductor group when inductor especially requires multiple same specifications, same occasion while worked is low into the problem of high, volume is big, poor reliability.A kind of the present invention is intended to provide Multiple coil composite magnetic circuit inductor group, forming the inductor unit of inductor group mainly includes winding, magnet, it is characterized in that the inductor group is formed by more than 2 inductor units by sharing the composite magnetic circuit link that the yoke portion of the magnet is formed, the winding of each unit inductor the same side is opposite by the magnetic flux for sharing yoke portion to ensure around to identical.The present invention is used in the structure design of power electronics high-frequency inductor.
Description
Technical field
The present invention relates to a kind of inductor group, more particularly to a kind of inductor pass through common magnet yoke portion form it is compound
The inductor group of magnetic circuit, this inductor group are used in power electronics energy conversion system, belong to inductor structure designing technique neck
Domain.
Background technology
With the development of process of industrialization, inductor requires low cost, small size, high reliability, especially required multiple
For the inductor of same specification when same occasion works simultaneously, the inductor of commercialization at present is mostly the inductor of several same specifications
Spelling group is together.There is individual manufacturer to lean on structure member mechanically coupled together the inductor of several same specifications, it is each independent
Work, does not have magnetic linkage relation between each other, the composite magnetic circuit yet just not shared, and cost is high, and volume is big.
The content of the invention
The present invention is intended to provide a kind of Multiple coil composite magnetic circuit inductor group, the inductor unit for forming inductor group is main
Including winding, magnet, it is characterised in that yoke portion of the inductor group by more than 2 inductor units by the shared magnet
The composite magnetic circuit link of composition forms, and the winding of each unit inductor the same side is around to identical, to ensure by sharing yoke portion
Magnetic flux is opposite；At work, sharing yoke portion can adapt to the inductor group in the rated flux of 0~inductor unit
Inevitably there are the different changes of electric current in real work in each inductor unit winding, improves the reliable of inductor group
Property；The sectional area in the shared yoke portion is equal with the sectional area at other positions of its magnet, so, relative to two same specifications
For separate inductor, a magnet yoke portion can be saved, material is also just saved, reduces cost, reduce volume.
Brief description of the drawings
Fig. 1 is the axonometric drawing of institute's inductor group of the present invention；
Fig. 2 is the axonometric drawing that inductor unit of the present invention forms " L " shape inductor group by evolution；
Fig. 3 is the axonometric drawing that inductor unit of the present invention forms Z-shaped inductor group by evolution；
