Abstract
The utility model discloses an LLC high-frequency transformer. The LLC high-frequency transformer comprises a skeleton and a magnetic core component penetrated inside the skeleton, wherein the skeleton is provided with a first wire winding portion and a second wire winding portion arranged in parallel; a primary coil is wound on the first wire winding portion; a secondary coil is wound on the second wire winding portion; the skeleton is provided with a retaining wall; the retaining wall is used for partitioning the first wire winding portion and the second wire winding portion. According to the LLC high-frequency transformer, the coupling degree of the primary coil and the secondary coil can be adjusted by adjusting the width of the retaining wall, thus the leakage inductance of the transformer is accurately adjusted, and high-frequency transformers with different transformer leakage inductances are convenient to obtain so as to meet the resonance inductance requirement of the transformer.
Description
Technical field
The utility model relates to a kind of transformer, is specifically related to a kind of LLC high frequency transformer.
Background technology
Power supply, when adopting resonant mode to open up benefit mode, need to be used transformer and resonant inductance.Conventional solution has following two kinds: the first, independently separately, wasting space so not only, and make PCB plate cabling complexity, electromagnetic interference large, causes that product efficiency is low, volume is large, cost is high for transformer and resonant inductance.The second, resonant inductance is integrated in transformer simply, utilize the leakage inductance of transformer to do resonant inductance use, this mode will be that enamelled wire is wound on the skeleton of customization conventionally, armature winding is arranged on a side of skeleton, secondary winding is arranged on the opposite side of skeleton, the leakage inductance that changes transformer by the distance changing between primary and secondary winding is to reach the requirement of resonant inductance, yet the transformer of this mode is higher to the structural requirement of transformer framework when requiring leakage inductance to change, cause transformer framework structure complicated.
Utility model content
For the deficiencies in the prior art, the utility model proposes a kind of LLC high frequency transformer, it realizes the adjusting to transformer leakage inductance easily.
In order to achieve the above object, the technical scheme that the utility model adopts is as follows:
A kind of LLC high frequency transformer, comprise that a skeleton and is arranged in intraskeletal core assembly, on described skeleton, be set side by side with the first winding section and the second winding section, on the first winding section, be wound with primary coil, on the second winding section, be wound with secondary coil, described skeleton is provided with a barricade, and this barricade is used for separating the first winding section and the second winding section.
Preferably, described barricade is nonwoven layer.
Compared with prior art, the utility model adopts a barricade to separate the first winding section and the second winding section, and the width of barricade can regulate as required, thereby regulate the degree of coupling of primary coil and secondary coil, thereby the leakage inductance to transformer realizes accurate adjustment, obtain easily the high frequency transformer of different transformer leakage inductances, to meet the requirement of transformer resonance inductance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of LLC high frequency transformer of the utility model;
Fig. 2 is the longitudinal profile schematic diagram of Fig. 1.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further, so that clearer, understand the utility model technological thought required for protection.
As shown in Figure 1, be the structural representation of a kind of LLC high frequency transformer of the utility model, comprise a skeleton 200, in this skeleton 200, be provided with an accommodation space for accommodating core assembly, core assembly is located in this accommodation space.On skeleton 200, be set side by side with the first winding section 210 and the second winding section 220, wherein on the first winding section 210, be wound with on primary coil 310, the second winding sections 220 and be wound with secondary coil 320.
In the utility model, skeleton 200 is provided with a barricade 230, and this barricade 230 is for separating the first winding section and the second winding section.The width of barricade 230 can arrange as required, and the barricade 230 of different in width is set, distance between primary coil 310 and secondary coil 320 also changes thereupon, therefore can regulate the degree of coupling of primary coil and secondary coil by the width of adjusting barricade 230, thereby the leakage inductance of transformer is realized to accurate adjustment.Meanwhile, resonant inductance of the present utility model is integrated in transformer simply, and the leakage inductance of transformer is resonant inductance, regulates leakage inductance that the width of barricade 230 just can change transformer to reach the requirement of resonant inductance.
In the present embodiment, primary coil 310 can adopt layering coiling, adjacent is provided with an insulating tape 330 between two-layer, and this insulating tape 330 draws adhesive tape for agate.Secondary coil 320 can adopt layering coiling, adjacent is provided with an insulating tape 330 between two-layer.
As preferably, barricade 230 adopts nonwoven layer.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion all should belong to the protection range of the utility model claim within.
Claims (2)
1. a LLC high frequency transformer, comprise that a skeleton and is arranged in intraskeletal core assembly, on described skeleton, be set side by side with the first winding section and the second winding section, on the first winding section, be wound with primary coil, on the second winding section, be wound with secondary coil, it is characterized in that: described skeleton is provided with a barricade, this barricade is used for separating the first winding section and the second winding section; Primary coil adopts layering coiling, adjacent is provided with an insulating tape between two-layer; Secondary coil adopts layering coiling, adjacent is provided with an insulating tape between two-layer.
