Abstract
The utility model discloses a plane high-frequency switching transformer, which comprises magnetic cores and coil windings arranged on the magnetic cores. The magnetic cores are flat frame-shaped magnetic cores. By using the plane high-frequency switching transformer, the defects of a conventional high-frequency switching transformer are overcome, and the height of the high-frequency switching transformer can be decreased. A wound conducting coil can be a single-layer coil, so that the skin effect and the proximity effect of the high-frequency switching transformer are decreased greatly, and the power density of the high-frequency switching transformer is improved greatly. Due to the planarity of the magnetic cores used by the high-frequency switching transformer, the heat-radiating area of the high-frequency switching transformer is increased greatly, so that the temperature rise of the high-frequency switching transformer is decreased greatly.
Description
Technical field
The utility model relates to a kind of transformer, specifically is meant a kind of plane high frequency switch transformer.
Background technology
At present, in the middle of prior art, traditional high frequency switch transformer all adopts the enclosed shape magnetic core of different shape, is wound with the multilayer conductive coil therein on the post.Because the HF switch converter has distinctive signal waveform, thereby makes traditional high frequency switch transformer have serious skin effect and proximity effect, can cause the power density of high frequency switch transformer to be restricted, temperature rise is also higher.In addition, to make that also the height of high frequency switch transformer can't be done very low for the core const ruction of traditional high frequency switch transformer.
The utility model content
The purpose of this utility model is to provide a kind of core planeization, highly little, area of dissipation is big, temperature rise is low plane high frequency switch transformer.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the plane high frequency switch transformer, comprise magnetic core and the coil windings that is arranged on the magnetic core, and described magnetic core is flat shaped as frame magnetic core.
Described magnetic core is made up of two halves, and its composition surface is arranged on the centre on two long limits of shaped as frame.
Described magnetic core is made up of two halves, and its composition surface is arranged on the centre of two minor faces of shaped as frame.
Described coil windings is arranged on the long limit of shaped as frame magnetic core.
Described coil windings is the single or multiple lift coil windings.
The utility model also comprises winding bracket, and described coil windings is wound on the winding bracket, and winding bracket is installed on the magnetic core.
Owing to adopted above-mentioned structure, the utlity model has following beneficial effect:
1, adopts flat shaped as frame magnetic core, reduced the height of high frequency switch transformer, make high frequency switch transformer can make writing board shape.
2, adopt flat shaped as frame magnetic core, the area of dissipation of high frequency switch transformer is increased, can reduce the temperature rise of high frequency switch transformer.
3, adopt the single layer winding mode, reduced the proximity effect of high frequency switch transformer, the current density of Transformer Winding is promoted, and the power density of high frequency switch transformer obtains very big increase, saves used core material and the winding material of high frequency switch transformer.
4, can be with the diverse location of winding technique at magnetic core, covering to be convenient to form has the integrated inductor of certain degree of coupling assembly.
