Description
Technical field
The present invention relates to a kind of transformer device structure, relating in particular to a kind ofly increases magnetic leakage sense (leakageinductance), guarantees the electrical safety distance of inner winding department and the transformer device structure of improving electric safety.
Background technology
Transformer is the electronic component that often uses in the various electric equipment.See also Fig. 1, it is the structural representation of a traditional transformer.As shown in Figure 1, this transformer 1 mainly comprises magnetic core set 11 (magneticcore assembly), winding base 12 (bobbin), elementary coiling 13 (primary winding coil) and secondary rolling thread 14 (secondary winding coil).Wherein, elementary coiling 13 and secondary rolling thread 14 are to overlap each other ground (overlap) lap wound in the winding section 121 of winding base 12, and with for example insulating tape 15 (isolation tape) insulated separation.Magnetic core set 11 is made up of first magnetic core component 111 and second magnetic core component 112 usually, the part-structure of magnetic core set 11, for example axle center part 111a, the 112a of first magnetic core component 111 and second magnetic core component 112, be arranged in the passage 122 of winding base 12, make magnetic core set 11 and elementary coiling 13 and secondary rolling thread 14 produce the electromagnetic coupled induction, thereby reach the purpose of voltage transitions.
Generally speaking, the control of transformer magnetic leakage sense (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 promoting the power conversion efficiency of power supply changeover device, correlation technique has been devoted to increase the coupling efficiency of transformer coiling, reduces the magnetic leakage sense, and then reduces the energy loss of voltage transitions.In transformer device structure shown in Figure 1, because elementary coiling 13 is to overlap each other the ground lap wound in the winding section 121 of winding base 12 with secondary rolling thread 14, therefore elementary coiling 13 forms less magnetic leakage with secondary rolling thread 14, coiling coupling efficiency (coupling coefficient) is higher, the magnetic leakage sense is lower, energy loss through the transformer changing voltage is less, can promote the power conversion efficiency of power supply changeover device thus.
Yet in the power system of electronic products of new generation such as for example LCD TV, transformer is a main flow with the transformer of tool magnetic leakage sense type.In the application of this class, the LC resonant circuit that the electric current of power system can be earlier constituted through the intrinsic magnetic leakage sense L of a transformer primary and a capacity cell 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 switching loss, the reduction noise of switch element and promote usefulness with resonant circuit.
The mode that increases the sense of transformer magnetic leakage has many kinds, and it mainly is that a specific range is separated in elementary coiling and secondary rolling thread, reduces the coiling coupling efficiency, thereby increases the magnetic leakage sense of transformer.See also Fig. 2, it is the structural representation of a traditional tool magnetic leakage sense type transformer.As shown in Figure 2, this transformer 2 comprises magnetic core set 21, winding base 22, elementary coiling 23, secondary rolling thread 24 and insulating tape 25, and wherein this winding base 22 has first side plate 221, second side plate 222 and winding section 223.Insulating tape 25 is wound in fact central position, winding section 223 and has width d, winding section 223 is divided into first winding region 2231 and second winding region 2232.Elementary coiling 23 is wound in respectively in first winding region 2231 and second winding region 2232 with secondary rolling thread 24, and pass through the first side adhesive tape 26 and the second side adhesive tape 27 and first side plate 221 and second side plate 222 separately respectively, separation by adhesive tape 25 can make keeps certain electrical safety distance between elementary coiling 23 and the secondary rolling thread 24, can make the electrical safety distance that also can keep meeting electrical safety between elementary coiling 23 and secondary rolling thread 24 and the outer member by the first side adhesive tape 26 and the second side adhesive tape 27 in addition.In addition, the insulating tape 25 width d that elementary coiling 23 and secondary rolling thread are 24 are wide more, and then representative coiling coupling efficiency reduces, and the magnetic leakage sense increases, and this will help the control of resonant circuit in the power system.
Yet,, still have many problems though above-mentioned transformer device structure can increase the magnetic leakage sense.For example, the size of magnetic leakage sense is the width d that depends on elementary coiling 23 and 24 adhesive tapes 25 of secondary rolling thread, because adhesive tape 25 is soft materials and can't be completely fixed, therefore structure is comparatively loose and easily be shifted because of using for a long time or shaking, cause magnetic leakage sense value to reduce or instability, and then have influence on the resonant circuit control of power system.In addition, when high-voltage applications, adhesive tape also can't provide enough electrical safety distances in winding department effectively.In addition, make separator to keep the mode of electrical safety distance with adhesive tape 25, the first side adhesive tape 26 and the second side adhesive tape 27, need manually to carry out in a large number the action that adhesive tape twines, 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, take manpower and cost on foot.Even, also may be because of the not good quality that has influence on transformer of the winding of adhesive tape.
Therefore, how to develop a kind of disappearance of improving the known transformer structure, and can effectively control with increase the magnetic leakage sense, guarantee inner winding department safe distance, improving electric safety, simple in structure, can simplify process, save the transformer device structure of artificial and cost, be the problem that presses for solution at present really.
