Description
Technical field
The present invention relates to a kind of transformer device structure, refer to it is a kind of transformer whose drain inductance structure that increases especially.
Background technology
Transformer is the electronic building brick that often uses in the various electric equipments.See also Fig. 1, it is the structural representation of a traditional transformer.As shown in Figure 1, this transformer 1 mainly comprises an iron core group 11 (magnetic core assembly), a winding base 12 (bobbin), main coiling 13 (primarywinding coil) and level coiling 14 (secondary winding coil) etc.Wherein, main coiling 13 and secondary rolling thread about in the of 14 lap wound in the winding region of winding base 12, and with an adhesive tape 15 (tape) separation insulated from each other.Iron core group 11 is generally EE sections core (EE-core), EI sections core (EI-core) or ER sections core (ER-core), it can be arranged at axle center 111 in the sleeve pipe 121 of winding base 12, make iron core group 11 and main coiling 13 and secondary rolling thread 14 produce the electromagnetic coupled induction, to reach the purpose of voltage transitions.
The control of transformer leakage inductance (leakage inductance) is very important to power supply changeover device, because it will have influence on the power conversion efficiency of power supply changeover device.For improving the power conversion efficiency of power supply changeover device, correlation technique has been devoted to increase the coupling efficiency of transformer coiling, reduces leakage inductance, and then reduces the energy loss of voltage transitions.In transformer device structure shown in Figure 1, since main coiling 13 and secondary rolling thread about in the of 14 lap wound in the winding region of winding base 12, therefore main coiling 13 forms less magnetic leakage with secondary rolling thread 14, coiling coupling efficiency (coupling coefficient) increases, leakage inductance reduces, energy loss through the transformer changing voltage is less, so just can improve the power conversion efficiency of power supply changeover device.
Yet in the power system of electronic products of new generation such as LCD TV, transformer is a main flow to have transformer whose drain inductance.The LC resonant circuit that the electric current of power system can be earlier constituted through the intrinsic leakage inductance L of a transformer primary and a capacitance component C; Simultaneously, the electric current that is similar to half sine wave can pass through power field effect transistor switch.When electric current was zero, switch was conducting, and when returning zero through half sinusoidal wave after-current, switch will cut out.Adopt this soft switch designs, can reduce the switching loss and reduction noise of switch module with resonant circuit.
The mode that increases transformer leakage inductance has many kinds, and it mainly is that the main coiling is separated a specific range with secondary rolling thread, reduces the coiling coupling efficiency, to increase the leakage inductance of transformer.See also Fig. 2, it is the structural representation that a tradition has transformer whose drain inductance.As shown in Figure 2, this transformer 2 comprises a winding base 21,22, level coilings of main coiling, 23 and one adhesive tape 24, and wherein this winding base 21 has one first side plate 211, one second side plate 212 and winding section 213.Adhesive tape 24 is wound in central in fact position, winding section 213 and has a width d, winding section 213 is divided into one first winding region 2131 and one second winding region 2132.Main coiling 22 is wound in respectively in first winding region 2131 and second winding region 2132 with secondary rolling thread 23, and respectively separately with one first side adhesive tape 25 and one second side adhesive tape 26 and first side plate 211 and second side plate 212, separation by adhesive tape 24 can make between main coiling 22 and the secondary rolling thread 23 and keep certain electrical safety distance, in addition by the first side adhesive tape 25 and the second side adhesive tape 26 can make wind the line 22,23 and the external conductive thing between also can keep meeting the electrical safety distance of electrical safety.In addition, the adhesive tape 24 width d that main coiling 22 and secondary rolling thread are 23 are wide more, and then representative coiling coupling efficiency reduces, and leakage inductance increases, and this will help the control of resonant circuit in the power system.
Yet,, still have many problems though said structure can increase leakage inductance.For example, the size of leakage inductance depends on the width d of main coiling 22 and 23 adhesive tapes 24 of secondary rolling thread, because adhesive tape 24 soft materials and can't being completely fixed, therefore structure is comparatively loose and easily be shifted because of using for a long time or shaking, cause the reduction or the instability of leakage inductance value, and then have influence on the resonant circuit control of power system.In addition, do separator to keep the mode of electrical safety distance with adhesive tape 24, the first side adhesive tape 25 and the second side adhesive tape 26, need manually to carry out the action that adhesive tape twines in a large number, because adhesive tape has stickiness and width is again little, therefore it is not only time-consuming but also loaded down with trivial details to add man-hour, cause production capacity to promote, consume manpower and cost in vain.What is more, also may be because of the not good quality that has influence on transformer of the winding of adhesive tape.
In addition, owing to need on the winding section 213 of winding base 21, to twine adhesive tape 24, the first side adhesive tape 25 and the second side adhesive tape 26, area and the volume that main coiling 22 and secondary rolling thread 23 can be twined in the winding section 213 reduced, and then have influence on the usefulness of heat radiation.Moreover transformer can be covered with the one layer tape insulation again outside main coiling 22 and secondary rolling thread 23 after coiling and the step that twines adhesive tape are finished, and the heat that coiling 22,23 is produced is difficult for leaving.What is more, the fusing point of adhesive tape 24 is lower, and therefore the Operating Temperature Limit value of whole transformer just is subjected to the fusing point restriction of adhesive tape 24, causes transformer application limited.
And, progress along with electronics technology, electronic equipment requires increasing for the power conversion efficiency of power supply changeover device, for example: require transformer the voltage transitions of 400V to be become the voltage of 2000V, because the magnitude of voltage after the conversion is excessive, therefore aspect the safety standard specification (being safety) of product, then require the main coiling of transformer and the electrical safety distance between secondary rolling thread to strengthen, just can avoid the phenomenon that connects the insulating barrier between main coiling and the secondary rolling thread and then make generation conducting between main coiling and the secondary rolling thread because the magnitude of voltage of conversion is excessive.And in Fig. 2 known technology, utilize width d that adhesive tape 24 is twined insulate main coiling 22 and secondary rolling thread 23, too short and voltage is crossed and will be connected very much adhesive tape 24 and make conducting between main coiling 22 and the secondary rolling thread 23 owing to distance, to cause electronic equipment to meet the requirements, and can't use.
Therefore, how to develop a kind of defective of improving known transformer device structure, and can effectively control with increase leakage inductance, improve electrical security, simple in structure, can simplify manufacture process, can meet safety and require, save transformer device structure artificial and cost, real is the problem that presses for solution at present.
