Description
本發明係有關一種變壓器，尤指一種漏感調整變壓器。The invention relates to a transformer, in particular to a leakage inductance adjusting transformer.
變壓器為目前電子設備中常用的電子元件，主要由一線架、一鐵心組、一初級線圈、以及一次級線圈所組成，其中該初級線圈與該次級線圈纏繞於該線架上，而該鐵心組穿設該線架與該初級線圈與該次級線圈產生電磁耦合感應，達到電壓轉換的目的。The transformer is a commonly used electronic component in electronic devices, and is mainly composed of a wire frame, a core group, a primary coil, and a primary coil, wherein the primary coil and the secondary coil are wound on the wire frame, and the core The group wears the wire frame and the primary coil and the secondary coil generate electromagnetic coupling induction to achieve voltage conversion.
變壓器的漏感(leakage inductance)為該初級線圈與該次級線圈之間的耦合並未達到百分之百，該初級線圈所產生的磁力線無通過次級線圈的部分產生漏磁的電感即為漏感，也就是該變壓器的該初級線圈與該次級線圈在耦合的過程中漏掉的部分磁通。以往在變壓器的設計上，皆希望能夠增加變壓器初級與次級線圈的耦合率，降低漏感以減少電壓轉換的能量損失。然而，在液晶電視等新一代的電子設備的電源供應系統中，則以具漏感型的變壓器為主流，可降低電流中的雜訊。目前用以增加漏感的變壓器如中華民國第I2911831號專利，其為一種變壓器結構，至少包括一主級繞線、一次級繞線、一繞線架模組與一鐵心組。鐵心組係設置於繞線架模組中，繞線架模組則包括一第一繞線部件與一第二繞線部件，該第一繞線部件係用於纏繞該主級繞線，該第二繞線部件係用於纏繞該次級繞線。其中，每一該第一繞線部件與該第二繞線部件具有一第一側板，且該第一繞線部件與該第二繞線部件彼此以該第一側板相間隔或連接，俾使該主級繞線與該次級繞線相分隔，以增加漏電感及電氣安全距離。然而，此方法所能調整的漏感值為一定值，並無法依照不同需求即時做調整。The leakage inductance of the transformer is such that the coupling between the primary coil and the secondary coil is not 100%, and the magnetic flux generated by the primary coil does not have a leakage inductance through the portion of the secondary coil, which is a leakage inductance. That is, part of the magnetic flux that the primary coil of the transformer and the secondary coil are missing during the coupling process. In the past, in the design of transformers, it is desirable to increase the coupling ratio between the primary and secondary coils of the transformer and reduce the leakage inductance to reduce the energy loss of voltage conversion. However, in a power supply system of a new generation of electronic devices such as a liquid crystal television, a leakage-sensitive transformer is mainly used, and noise in the current can be reduced. The current transformer for increasing the leakage inductance, such as the Republic of China No. I2911831, is a transformer structure comprising at least a main winding, a primary winding, a winding frame module and a core group. The core group is disposed in the bobbin module, and the bobbin module includes a first winding component and a second winding component, wherein the first winding component is used for winding the main winding. A second winding component is used to wind the secondary winding. Wherein each of the first winding member and the second winding member has a first side plate, and the first winding member and the second winding member are spaced or connected to each other by the first side plate, so that The primary winding is separated from the secondary winding to increase leakage inductance and electrical safety distance. However, the leakage inductance that can be adjusted by this method is a certain value, and it cannot be adjusted immediately according to different needs.
有鑑於此，為了能更方便的依情況需求而調整漏感值，遂有改良如中華民國第I280720號專利，其為一種定頻電源供應器，應用於具有一次側及二次側之一切換式電路上，該定頻電源供應器包含有：一第一鐵心、一第二鐵心、一第一線架以及一第二線架，該第一鐵心以及一第二鐵心為相對應設置，其分別具有一第一凸體與一第二凸體；該第一線架位於該第一凸體上，該第一線架纏繞有第一組線圈以及電訊連接一次側之一第一組接腳；該第二線架位於該第二凸體上，該第二線架纏繞有第二組線圈以及電訊連接二次側之一第二組接腳；其中，該第一線架更包括有可套合該第二線架之一套口，使該第一線架與該第二線架可利用該套口形成一滑動伸縮，於該第一凸體與該第二凸體上進行位移運動，而進行調整該一次側及二次側間之電感。然而，該第一線架與該第二線架之間彼此間並無法固定，該第一線架與該第二線架的相會位置容易改變，以至於該二線圈之間的間隙無法固定，在組裝時無法準確地按照預設的間隙組裝，而有電感值與預設不同的問題產生。再者，上述透過架體滑動伸縮改變線架長度進而改變一次側與二次側之間的結構，雖然可以調整電感值，但一般來說同一線架的鐵心組規格是固定的，其鐵心組的長度是配合線架長度而定，而如上述可調整長度之線架若其鐵心組長度固定，當調整線架長度時，固定規格的該鐵心組的二鐵心之間的距離即會改變，連帶改變電感值大小，因此這種伸縮線架在使用上必須要經過精密的計算才能將漏感值調整到預想的值，十分麻煩。In view of this, in order to adjust the leakage inductance value more conveniently according to the needs of the situation, there is a improvement such as the Republic of China No. I280720 patent, which is a fixed-frequency power supply, which is applied to one of the primary side and the secondary side. On the circuit, the fixed frequency power supply includes: a first core, a second core, a first wire frame and a second wire frame, wherein the first core and a second core are correspondingly disposed, Each has a first protrusion and a second protrusion; the first wire frame is located on the first protrusion, and the first wire frame is wound with the first set of coils and one of the first set of pins on the primary side of the telecommunication connection The second wire frame is located on the second protrusion, the second wire frame is wound with a second set of coils and a second set of pins of the secondary side of the telecommunication connection; wherein the first wire frame further comprises The first wire frame and the second wire frame are configured to form a sliding expansion and contraction, and the first convex body and the second convex body are displaced. And adjust the inductance between the primary side and the secondary side. However, the first wire frame and the second wire frame are not fixed to each other, and the meeting position of the first wire frame and the second wire frame is easily changed, so that the gap between the two coils cannot be fixed. When assembling, it is impossible to accurately assemble according to the preset gap, and there is a problem that the inductance value is different from the preset. Furthermore, the above-mentioned sliding frame expansion and expansion changes the length of the wire frame to change the structure between the primary side and the secondary side. Although the inductance value can be adjusted, generally, the core group specification of the same wire frame is fixed, and the core group is fixed. The length of the wire frame is determined according to the length of the wire frame, and if the length of the wire frame of the adjustable length is fixed, when the length of the wire frame is adjusted, the distance between the two cores of the core group of the fixed specification changes. In conjunction with changing the value of the inductance, the use of such a retractable wire frame must be carefully calculated to adjust the leakage inductance value to the expected value, which is very troublesome.

請復參閱圖2，更具體來說，該繞線架1為由二半體1a、1b所組成的，該半體1a包含該第一繞線部11、設於該第一繞線部11上該第一螺紋部12、一設於該第一繞線部11一端的第一組接部15、以及一設於該第一繞線部11內供該鐵心組2穿設的第一通道16。而另外該半體1b包含該第二繞線部13、設於該第二繞線部13上的該第二螺紋部14、一設於該第二繞線部13一端與該第一組接部15組接的第二組接部17、以及一設於該第二繞線部13內與該第一通道16連通的第二通道18。該第一調整部31具有一與該第一螺紋部12相配的第一內螺紋部311，該第二調整部32具有一與該第二螺紋部14相配的第二內螺紋部321。Referring to FIG. 2, more specifically, the bobbin 1 is composed of two halves 1a and 1b.

請參閱圖3及圖4，本發明於組裝時，僅需將該第一調整部31與該第一螺紋部12螺接，並將該第二調整部32與該第二螺紋部14螺接，之後再將該二半體1a、1b以該第一組接部15與該第二組接部17組接在一起，接著再將該第一線圈41纏繞於該第一繞線部11上作為該漏感調整變壓器的一次側，以接收一電力來源所提供的電流並將該電流轉換為磁能，該第二線圈42纏繞於該第二繞線部13上作為該漏感調整變壓器的二次側，接收該磁能再轉換為電流。其中，該第一線圈41與該第二線圈42為一絞線，該第一線圈41的線徑大於該第一螺紋部12的螺距且該第二線圈的線徑大於該第二螺紋部的螺距，令該第一線圈41與該第二線圈42在纏繞時不會卡合於該第一螺紋部12與該第二螺紋部14內。最後，再將該鐵心組2穿過該第一通道16與該第二通道18與該繞線架1組裝。Referring to FIG. 3 and FIG. 4 , in the assembly of the present invention, only the first adjusting portion 31 is screwed to the first thread portion 12 , and the second adjusting portion 32 is screwed to the second thread portion 14 . Then, the two halves 1a, 1b are assembled with the first set of joints 15 and the second set of joints 17, and then the first coil 41 is wound around the first winding portion 11. As a primary side of the leakage inductance adjusting transformer, to receive a current supplied from a power source and convert the current into magnetic energy, the second coil 42 is wound around the second winding portion 13 as the leakage inductance adjusting transformer On the secondary side, the magnetic energy is received and converted into a current. The first coil 41 and the second coil 42 are a stranded wire, the wire diameter of the first coil 41 is larger than the pitch of the first threaded portion 12, and the wire diameter of the second coil is larger than the second threaded portion. The pitch is such that the first coil 41 and the second coil 42 do not engage in the first threaded portion 12 and the second threaded portion 14 when being wound. Finally, the core group 2 is assembled through the first passage 16 and the second passage 18 with the bobbin 1.
請參閱圖4，而本發明漏感調整變壓器，透過調整該第一調整部31與該第二調整部32的位置，來調整該間距33的大小，進而可調整該第一線圈41與該第二線圈42的漏感值大小。具體來說，若希望增加漏感值，僅需於纏繞該第一線圈41與該第二線圈42之前旋轉該第一調整部31與該第二調整部32，令該第一調整部31沿該第一螺紋部12遠離該第二調整部32位移，且令該第二調整部32沿該第二螺紋部14遠離該第一調整部31位移，此時該間距33增加，纏繞後該第一線圈41與該第二線圈42之間的距離也隨之增加，進而增加漏感值。反之，若希望減少漏感值，旋轉該第一調整部31與該第二調整部32，令該第一調整部31與該第二調整部32彼此相互靠近，進而減少該間距33，而使該第一線圈41與該第二線圈42之間的距離減少，進而減少漏感值。Referring to FIG. 4, the leakage inductance adjusting transformer of the present invention adjusts the position of the first adjusting portion 31 and the second adjusting portion 32 to adjust the size of the spacing 33, thereby adjusting the first coil 41 and the first The magnitude of the leakage inductance of the two coils 42. Specifically, if it is desired to increase the leakage inductance value, the first adjustment portion 31 and the second adjustment portion 32 are rotated before the first coil 41 and the second coil 42 are wound, so that the first adjustment portion 31 is along The first threaded portion 12 is displaced away from the second adjusting portion 32, and the second adjusting portion 32 is displaced along the second threaded portion 14 away from the first adjusting portion 31. At this time, the spacing 33 is increased, and the winding portion is The distance between a coil 41 and the second coil 42 also increases, thereby increasing the leakage inductance value. On the other hand, if it is desired to reduce the leakage inductance value, the first adjustment portion 31 and the second adjustment portion 32 are rotated, so that the first adjustment portion 31 and the second adjustment portion 32 are close to each other, thereby reducing the pitch 33, thereby making the gap 33 The distance between the first coil 41 and the second coil 42 is reduced, thereby reducing the leakage inductance value.
此外，一般習用的變壓器其線圈的捲繞方式較鬆散，各圈絞線與絞線之間具有間距，而本發明在組裝的過程中，僅需調整該第一線圈41的各圈絞線之間的距離以及該第二線圈42的各圈絞線之間的距離，換句話說，就是在不改變線圈匝數的情況下，調整該第一線圈41與該第二線圈42之纏繞密度，因此本發明可以在不改變該繞線架1長度的情況下固定線圈匝數並調整漏感值。In addition, the conventionally used transformer has a loose winding manner of the coil, and there is a spacing between the twisted wires and the stranded wires, and in the assembly process of the present invention, only the twisted wires of the first coil 41 need to be adjusted. The distance between the distances and the distance between the loops of the second coil 42 , in other words, the winding density of the first coil 41 and the second coil 42 is adjusted without changing the number of turns of the coil, Therefore, the present invention can fix the number of turns of the coil and adjust the leakage inductance value without changing the length of the bobbin 1.
綜上所述，透過本發明的該第一螺紋部12、該第二螺紋部14、該第一調整部31、以及該第二調整部32的設計，以旋轉的方式調整該間距33，也就是調整該第一線圈41與該第二線圈42之間的距離，進而調整該第一線圈41與該第二線圈42的漏感值。且配合該第一調整部31與該第二調整部32之間的該間距33大小調整該第一線圈41與該第二線圈42的繞線密度，而能在不改變該繞線架1長度的狀況達到調整漏感的功效。更進一步來說，該繞線架1的長度不變，則該鐵心組的規格即可固定，而無習用調整漏感變壓器的鐵心組的二鐵心之間的距離會因線架長度改變而改變的問題。In summary, through the design of the first threaded portion 12, the second threaded portion 14, the first adjusting portion 31, and the second adjusting portion 32 of the present invention, the spacing 33 is adjusted in a rotational manner. That is, the distance between the first coil 41 and the second coil 42 is adjusted, and the leakage inductance values of the first coil 41 and the second coil 42 are adjusted. And adjusting the winding density of the first coil 41 and the second coil 42 according to the spacing 33 between the first adjusting portion 31 and the second adjusting portion 32, without changing the length of the bobbin 1 The condition has reached the effect of adjusting the leakage. Furthermore, if the length of the bobbin 1 is constant, the specification of the core group can be fixed, and the distance between the two cores of the core group without the conventional adjustment leakage inductance transformer changes due to the change of the length of the bobbin.
