Description
Technical field
The present invention relates to a kind of transformer, particularly relates to a kind of circuit arrangement that is applied to need the transformer of leakage inductance characteristic in the power transfer module and is used for control transformer.
Background technology
As shown in Figure 1, 2, first kind of existing transformer 1 comprises a drum stand 11, two iron cores 12, primary side magnetizing coil 13, secondary side induction coil 14, an insulation film 15, and a shell 16.
This drum stand 11 is a hollow support body, and has most demarcation strips 111 to be distinguished into two winding sections 112,113, reaches the lead terminal 114 that most spaces are positioned at both sides.
Its assembling, be that two enamelled wires 131,141 in collinear footpath are not wrapped on the described winding section 112,113 to constitute primary side magnetizing coil 13 and secondary side induction coil 14, and this secondary side induction coil 14 is to be wound with most layers in a continuous manner in an overlapping, and is coated between each layer by this insulation film 15.Described iron core 12 is to be extended through to be bonded with each other in the hollow bulb 115 of this drum stand 11 to constitute a closed magnetic path, adjust primary side magnetizing coil 13 via described demarcation strip 111 thickness size and obtain required leakage inductance characteristic with the spacing of secondary side induction coil 14, yet, when cause is adjusted leakage inductance by adjusting demarcation strip 111 or setting up barricade thickness, owing to be difficult for obtaining control when a large amount of production, the efficient quality in this transformer 1 electrical characteristic is unstable.
Shown in Fig. 3,4, second kind of existing transformer 2 comprises a drum stand 21, an iron core group 22, primary side magnetizing coil 23, and secondary side induction coil 24.
This drum stand 21 has a hollow bulb 211, and is formed between this first and second winding section 212,213 and the breach 214, two that is connected with this hollow bulb 211 lays respectively at the short slot 215 of these hollow bulb 211 both end sides and most the lead terminals 216 that are positioned at both sides separately for first winding section 212 of twining this primary side magnetizing coil 23, for second winding section 213, of twining this secondary side induction coil 24.
This iron core group 22 has first iron core 221 that penetrates in the hollow bulb 211 of this drum stand 21, and second iron core 222 that is centered around these drum stand 21 outsides, this second iron core 222 has two and extends and be cross-placed on first protuberance 2221 on the described short slot 215 towards this drum stand 21 directions from both end sides, and one extends second protuberance 2222 that penetrates this breach 214 and be connected to first iron core, 221 1 sides from the middle section towards these drum stand 21 directions.
This type of transformer is to utilize iron core group 22 formed magnetic circuits to separate primary side magnetizing coil 23 and secondary side induction coil 24, to increase the magnetic shunt footpath of leakage magnetic flux A, and the permeance of second protuberance 2222 that utilizes this second iron core 222 is to increase the purpose of its leakage inductance, but so also reduce coupling effect, because utilize magnetic conductive component to increase leakage magnetic flux, its magnetic capacity is between 2000～5000, this value is very high multiple, during practical application, accuracy is wayward, causes efficient not good.
According to as can be known last, general transformer, all be included in and be wound with a coil on the drum stand, an and iron core group that is centered around on this drum stand, and the canoe of this coil need form two windings at least, respectively this coil winding direction at least with an iron core portion in vertical direction, the magnetic line of force in order to this iron core portion induction coil generation, the winding canoe of primary side field winding and secondary side induction just is corresponding to mutually by the iron core group magnetic conduction and then produce coupling effect (as shown in Figure 4, flux M just is coupled), and utilize the number of turn of each winding recently to obtain required voltage, utilize the application of iron core group again, increase effective flux change, to improve the efficient of power transfer, yet, the meaning that winding around is corresponding mutually, all be in order to improve coupling effect, but, when reality is used, all can produce leakage inductance after the transformer production, thereby produce loss, therefore, prior art still can't reach under the situation of no leakage inductance, how the loss with leakage inductance utilizes resonance principle as power-conversion application, with effective control leakage inductance problem, is the target of the shared effort of each dealer.
