Optimize the driving transformer processed soon of coupling performance

Technical field

The utility model is related to the structure improved technology of driving transformer device, the fast system for especially optimizing coupling performance is driven Dynamic transformer.

Background technology

The basic principle of transformer is all based on electromagnetic induction principle, using the different circle of primary coil and secondary coil Conversion of the number than realizing voltage value size, the output voltage of transformer is very big with the influence of input network voltage and load, causes Spread of voltage.

Driving transformer has been widely used in the occasions such as Switching Power Supply, and driving transformer can realize square wave input, side Wave exports.But the presence of the parasitic parameter due to driving transformer itself, so as to be caused centainly to the use of driving transformer Influence.

Driving transformer requires good insulating properties in itself, such as the winding of existing isolation drive transformer is to adopt With more three-layer insulated conducting wires and it is wound on magnet ring, wherein, insulated conductor is made of insulator coated wire, and without twisted It is wound on magnet ring again later into a branch of, in this way, in winding process, line is more random, and the coupling effect between line and line obtains not To guarantee, leakage inductance can be bigger, and more preferable effect is not achieved in the performance of product.

Therefore in the prior art, conventional driving transformer winding is all independent layering coiling, is asked with the technology for solving aforementioned Topic.But this way, limit the coupling performance of coil, and coil winding process very very complicated, be susceptible to around Manufacturing quality is next.

Utility model content

The purpose of this utility model is to provide the driving transformer processed soon of optimization coupling performance, solution more than technical problem.

The purpose of this utility model will be realized by following technical measures：Including skeleton, the first winding, the second winding and The tertiary winding；Skeleton is wound with the coil windings including the first winding, the second winding and the tertiary winding, wherein, including bone Frame, the first winding, the second winding and the tertiary winding are with the identical parallel coiling that puts in order.

Especially, iron core is installed on skeleton.

Especially, there is shielded layer between inside and outside two layers of adjacent coil windings.

Especially, the first winding, the second winding, the tertiary winding are in coiling, the coiling direction of inside and outside two layers of coil windings On the contrary, use reciprocating coiling.

Especially, every layer of coil windings include the first winding, the second winding and the third of at least two circle same sequences arrangement Winding.

Especially, there is shielded layer on the outside of outermost one layer of coil windings.

Especially, every layer of coil windings, which are uniformly gathered, is wound in skeleton in winding slot, does not stay gap.

The advantages of the utility model and effect：By the way that each winding all and together on coiling skeleton, is saved process, winding Coiling speed is fast, and the coupling of transformer is good.Coil-winding spacing can be close to 0.1mm, in this way, the coupling effect between line and line Fruit can be fine, greatly reduces leakage inductance, improves the performance of product.The utilization rate in PCB printed circuit boards space can be improved, together When leakage inductance it is low, inductance value is high, and the distortion factor of signal can reduce, and the performance of product is more preferable.
