Description
Technical field
This utility model relates to transformer technology field, particularly relates to a kind of resonance transformer.
Background technology
Along with the release of efficiency six grade standard, the power more than 50w converts Switching Power Supply and requires transformation efficiency extremely
Few more than 85%, and general Switching Power Supply topology converter is difficult to meet standard.So LLC resonance is opened
Closing the application of electric source topology converter and give birth to, its transformation efficiency is up to more than 90%.Meanwhile, because of its excellent EMI
(Electromagnetic Interference, electromagnetic interference) characteristic, its application will be more and more extensive.
Its interior resonance transformer is the Primary Component of this topology, and its performance design will directly affect the performance of changer.
Resonance transformer designs at present mainly two kinds of technology:
In small-power occasion, the resonance transformer used as main power transformer uses the skeleton coiling of multiple-grooved
Design.The most main power transformer provides magnetizing inductance for resonant tank, because of the diversity of magnetic circuit, and primary line
The magnetic field that circle is encouraged can not be coupled to secondary coil completely, thus forms a certain size leakage field, for humorous
The circuit that shakes provides leakage inductance.So with peripheral resonant capacitance, form LLC resonant converter.Due to main power
The leakage inductance that transformator provides is the least, is provided leakage inductance so this by main power transformer, participates in resonance
Converter design, suitable for application in large-power occasions.And the function now with electrical equipment increases,
Electricity consumption integrated level is more and more higher, and this just requires that the power that power supply provides wants big.So it is this low power
Resonance transformer design is just not suitable with present demand.
In high-power applications occasion, one resonant inductance of extra increase in resonant tank often, i.e. at LLC
In controlled resonant converter, in addition to resonance transformer, an also resonant inductance, so cause the body of changer
Long-pending big, and now equipment to be required to volume little, this device density allowing for equipment is big, power density requirements
Height, so this design is also not suitable with the design requirement of present equipment；Meanwhile, because adds additional inductance,
Also accordingly increase material cost, have impact on the competitiveness of product in market.
Also have and reach to regulate leakage inductance by adjustment skeleton groove width (i.e. primary coil and the spacing of secondary coil)
Purpose, but this adjustment generally require amendment skeleton mould could realize, so cause project to be opened
The cycle of sending out is long, and Expenses Cost is high, DeGrain.
Utility model content
Technical problem to be solved in the utility model is to provide and a kind of the most additionally increases little humorous of device, cost
Shake transformator.
This utility model is achieved in that
A kind of resonance transformer, including magnetic core and skeleton, described magnetic core is located in described skeleton, described bone
Be wound with primary coil and the secondary coil of mutually insulated on frame, the side at described secondary coil place be provided with
Described secondary coil, magnetic core isolation, for regulating the regulation magnetic core of leakage inductance.
Further, described skeleton includes primary skeleton and secondary framework, described primary skeleton and secondary framework
In be all equipped with magnetic core, described primary coil is wound on primary skeleton, and described secondary coil is wound on secondary
On skeleton.
Further, it is provided with skeleton grooves between described primary skeleton and secondary framework.
Further, it is coated with insulating barrier outside described secondary coil.
Further, it is coated with insulating barrier outside described primary coil.
Further, magnetic core one end that described regulation magnetic core isolation is connected in described secondary coil.
Further, described regulation magnetic core is installed in outside the insulating barrier of secondary coil.
Further, described regulation magnetic core is installed in outside described secondary framework.
Further, described magnetic core is soft magnet core.
Further, described regulation magnetic core is Hard Magnetic iron core.
This utility model compared with prior art, has the beneficial effects that: in this transformator, by secondary wire
Circle side increases by a stable regulation magnetic core, improves transformer leakage inductance, thus promotes the through-put power of transformator,
So there is no need to the most additionally increase by a resonant inductance, thus reached to reduce the effect of volume；This transformation
Device reaches to regulate the purpose of leakage inductance also without by adjustment skeleton, i.e. need not revise the shaping mould of skeleton
Tool；This materials processing is convenient, and its size material can arbitrarily adjust, and debugging is convenient, shortens the construction cycle,
Reduce development cost.
Accompanying drawing explanation
Fig. 1: this utility model example structure schematic diagram.
In figure: 1-magnetic core 2-skeleton 21-primary skeleton 22-secondary framework 23-skeleton grooves 3-is primary
Coil 4-secondary coil 5-regulates magnetic core
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And embodiment, this utility model is further elaborated.
As it is shown in figure 1, be this utility model one preferred embodiment, a kind of resonance transformer, including magnetic core 1
With skeleton 2, magnetic core 1 is located in skeleton 2, and skeleton 2 is wound with primary coil 3 He of mutually insulated
Secondary coil 4, the side at secondary coil 4 place is provided with that insulate with secondary coil 4, magnetic core 1, for adjusting
The regulation magnetic core 5 of joint leakage inductance.
In this resonance transformer, by increasing by a stable regulation magnetic core 5 in secondary coil 4 side, improve and become
Depressor leakage inductance, thus promote the through-put power of transformator, so there is no need to the most additionally increase by a resonant inductance
, thus reached to reduce the effect of volume.This transformator reaches regulation also without by adjustment skeleton
The purpose of leakage inductance, i.e. need not revise the mould of skeleton 2.This materials processing is convenient, its size material
Matter can arbitrarily adjust, and debugging is convenient, shortens the construction cycle, reduces development cost.
Specifically, skeleton 2 includes primary skeleton 21 and secondary framework 22, primary skeleton 21 and secondary framework
