Description
Technical field
It the utility model is related to a kind of big leakage inductance transformer.
Background technology
In field of power electronics, especially in field of switch power, it usually needs either AC or DC sources are transformed into one
The high-precision stable state power supply of kind.The Switching Power Supply is generally made up of rectifier, inverter, three big device of transformer, by a kind of shape
High-precision stable state electric energy of the transformation of electrical energy of state (AC or DC) into same form or another form.Transformer is in the Switching Power Supply
In be in inverter rear end, play isolation and buck effect.
The audiorange that can be heard due to human ear is substantially in the range of 20Hz~20kHz, therefore the switching frequency of inverter
Be selected in mostly 20kHz and more than, this avoid making us irritated noise pollution, but it is humorous at the same time to produce many high orders
Ripple, rear class transformer and the power supply output quality of power supply are had an impact, therefore inverter and rear end transformer under normal conditions
Between can add a filter inductor, for suppressing and reducing higher harmonic content, improve the output quality of power supply.
Utility model content
The purpose of this utility model is to provide a kind of small volume, in light weight, inexpensive big leakage inductance transformer, and can
Obtain a high-precision leakage inductance value.
A kind of big leakage inductance transformer, including main iron core, secondary iron core, input lateral coil and output lateral coil, its special feature
It is：The input lateral coil and output lateral coil independently coiling, and the outlet side mounting coil is on main iron core, and
The input lateral coil is sleeved on main iron core and secondary iron core simultaneously；
Wherein also include folder, foregoing main iron core and secondary iron core are fixed to clamp in the folder, and the folder bottom passes through
Pressing plate is fixedly mounted on same bottom plate so as to form an entirety.
The utility model provides the good big leakage inductance transformer of a kind of high accuracy and stability, specifically by filter inductor
Accomplish the input side of transformer in the form of leakage inductance, in an additional secondary iron core for transformer main iron core, by adjusting secondary iron core
Size of gaps, obtain desired leakage inductance value.Due to adding secondary iron core, while main magnetic circuit is not influenceed, by adjusting gas
Gap size obtains the size of leakage inductance value, therefore is not limited completely by leakage inductance value size, and can obtain a high accuracy
Leakage inductance value.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
In the case where pursuing small volume, in light weight, the inexpensive market demand, the utility model is by filter inductor with leakage inductance
Form accomplishes the input side of transformer, and filter inductance and transformer are combined into one, and maximizes its cost performance, so as to meet city
Field demand.
Therefore, the utility model provides a kind of big leakage inductance transformer, including main iron core 1, secondary iron core 2, input lateral coil 3
With output lateral coil 4, the input lateral coil 3 and the output independently coiling of lateral coil 4, and the output lateral coil 4 is set with
On main iron core 1, and the input lateral coil 3 is sleeved on main iron core 1 and secondary iron core 2 simultaneously；Wherein also include folder 5, it is foregoing
Main iron core 1 and secondary iron core 2 fix to clamp in the folder 5, the bottom of folder 5 is fixedly mounted on same bottom by pressing plate 6
So as to forming an entirety on plate 7.
Application method and operation principle of the present utility model are：
The utility model provides the good big leakage inductance transformer of a kind of high accuracy and stability, when transformer works, transformation
The input side leakage inductance of device plays a part of filter inductance.When transformer input side flows through electric current, leakage inductance will suppress and reduce
The high order current harmonic content being superimposed in electric current, improve the output quality of power supply.
