網路變壓器及製造網路變壓器的方法Network transformer and method of making a network transformer

本發明的實施例是關於一種變壓器及製造變壓器的方法。更具體而言，本發明的實施例是關於一種網路變壓器及製造網路變壓器的方法。Embodiments of the present invention relate to a transformer and a method of manufacturing the same. More specifically, embodiments of the present invention relate to a network transformer and method of manufacturing a network transformer.

在現今的網路通訊架構中，各種電子裝置可經由局部區域網路（Local Area Network，LAN）而彼此連接。在高速的局部區域網路（例如1G、2.5G、5G、10Gbps）下傳遞及接收數據的情況下，傳輸訊號往往會受到嚴重的衰減及干擾，而網路變壓器是一種被設計來決如此問題的裝置。In today's network communication architecture, various electronic devices can be connected to each other via a local area network (LAN). In the case of transmitting and receiving data under high-speed local area network (such as 1G, 2.5G, 5G, 10Gbps), the transmission signal is often severely attenuated and interfered, and the network transformer is designed to solve this problem. installation.

阻抗不匹配容易造成訊號嚴重失真或電磁波散逸，而為了實現阻抗匹配，網路變壓器的特性阻抗（Characteristic Impedance）必須符合預設規格（即，網路變壓器的特性阻抗必須在特定工作頻段內維持在一預設範圍內）。特性阻抗與網路變壓器的電阻值、電感值與電容值有關，而網路變壓器的電阻值、電感值與電容值會因為其設計模式的不同而不同。一般來說，在網路變壓器的設計階段，可以完整地量測或估測出網路變壓器的電阻值與電感值，但由於纏繞在網路變壓器鐵芯上的複數漆包線之間的線電容在網路變壓器內的位置是相當分散的，故通常難以完整地量測或估測網路變壓器的電容值，這也導致無法在網路變壓器的設計階段就正確地計算出其特性阻抗，而是必須等到完成網路變壓器的設計之後，才根據設計好的網路變壓器的電阻值、電感值與電容值計算其特性阻抗。Impedance mismatch is likely to cause serious signal distortion or electromagnetic wave dissipation. In order to achieve impedance matching, the characteristic impedance (Characteristic Impedance) of the network transformer must meet the preset specifications (that is, the characteristic impedance of the network transformer must be maintained within a specific operating frequency band. within a preset range). The characteristic impedance is related to the resistance, inductance, and capacitance values of the network transformer, and the resistance, inductance, and capacitance values of the network transformer will vary due to its design mode. Generally speaking, in the design stage of the network transformer, the resistance value and inductance value of the network transformer can be completely measured or estimated, but due to the line capacitance between the complex enameled wires wound on the iron core of the network transformer The locations in the network transformer are quite scattered, so it is usually difficult to completely measure or estimate the capacitance value of the network transformer, which also makes it impossible to correctly calculate its characteristic impedance in the design stage of the network transformer. After the design of the network transformer is completed, the characteristic impedance of the network transformer can be calculated based on the resistance value, inductance value and capacitance value of the designed network transformer.

由於影響網路變壓器的特性阻抗的因子是難以控制的，一旦發現設計好的網路變壓器的特性阻抗不符合預設標準，傳統的做法是回到網路變壓器的設計階段，並對網路變壓器的設計模式進行調整，而這樣的做法顯然耗時費力而沒有效率。除此之外，當為了改變特性阻抗而調整網路變壓器的設計模式時，通常也將一併改變了網路變壓器的其他屬性（例如，***損失（Insertion Loss）、回波損失（Return Loss）等等），這將增加了將網路變壓器設計為同時符合多種預設標準（例如，特性阻抗標準、***損失標準、回波損失標準等等）的難度。因此，傳統的做法也不乏有直接降低或甚至不考慮網路變壓器的特性阻抗的預設標準。Since the factor affecting the characteristic impedance of the network transformer is difficult to control, once it is found that the characteristic impedance of the designed network transformer does not meet the preset standard, the traditional method is to return to the design stage of the network transformer and make an adjustment to the network transformer. It is obviously time-consuming, labor-intensive and inefficient. In addition to this, when the design pattern of a network transformer is adjusted in order to change the characteristic impedance, other properties of the network transformer (e.g., Insertion Loss, Return Loss) are usually also changed. etc.), which increases the difficulty of designing network transformers to comply with multiple preset criteria simultaneously (eg, characteristic impedance criteria, insertion loss criteria, return loss criteria, etc.). Therefore, there is no shortage of traditional practices with preset standards that directly reduce or even ignore the characteristic impedance of the network transformer.

有鑑於此，如何設計出一種能夠使網路變壓器符合特性阻抗標準的特定變壓器結構以及提供一種製造具備該特定變壓器結構的網路變壓器的方法，將是本發明所屬技術領域亟待解決的問題。In view of this, how to design a specific transformer structure that can make the network transformer meet the characteristic impedance standard and provide a method for manufacturing the network transformer with the specific transformer structure will be problems to be solved in the technical field of the present invention.

The first negative ground wire W12 and the first positive ground wire W21 together serve as the ground terminal of the primary side of the network transformer 1, wherein the first negative ground wire W12 and the first positive ground wire W21 are partially or completely twisted with each other, and The first negative ground wire W12 comes from the tail of the enameled wire W1, and the first positive ground wire W21 comes from the head of the enameled wire W2.

網路變壓器1的特性阻抗是由網路變壓器1的電阻值、電感值與電容值所決定，其中，該電感值主要取決於漆包線W1、W2、W3、W4纏繞變壓器鐵芯10的圈數，該電容值主要包含雜散電容值及線電容值。雜散電容值是指網路變壓器1的一次側與二次側之間所產生的電容，而線電容值是指形成在漆包線W1、W2、W3、W4之間的電容。由於第一正引線W11與第一負引線W22的互絞部分以及第二正引線W31與第二負引線W42的互絞部分可以在不改變網路變壓器1的設計模式的情況下額外增加網路變壓器1的線電容，進而使得網路變壓器1的特性阻抗符合一預設的特性阻抗標準。除此之外，該互絞結構還可改善網路變壓器的其他屬性（例如，***損失、回波損失等等）。The characteristic impedance of the network transformer 1 is determined by the resistance value, inductance value and capacitance value of the network transformer 1, wherein the inductance value mainly depends on the number of turns of the enameled wires W1, W2, W3, W4 wound around the transformer core 10, The capacitance value mainly includes stray capacitance value and line capacitance value. The stray capacitance value refers to the capacitance generated between the primary side and the secondary side of the network transformer 1, and the line capacitance value refers to the capacitance formed between the enameled wires W1, W2, W3, and W4.

Figure 3B, Figure 3D, and Figure 3F use the same network analyzer to measure the insertion loss, return loss and characteristic impedance of the network transformer improved according to the present invention. The resulting waveform. The only difference between the improved network transformer and the conventional network transformer is that the signal leads on the primary side and the secondary side of the improved network transformer are partially twisted with each other. The contents shown in FIGS. 3A to 3F are only for illustration, but not for limiting the protection scope of the present invention.

代表從差分埠1到差分埠1的差模增益（即，回波損失），

代表從差分埠1到差分埠2的差模增益，

代表從差分埠2到差分埠1的差模增益（即，***損失），

代表從差分埠2到差分埠2的差模增益。 The insertion loss and return loss of the improved network transformer and the traditional network transformer can be directly obtained through the signals measured by the differential port 1 and differential port 2 of the network analyzer, and the improved network transformer can be further calculated according to the following equations.

如圖3A~3B所示，在相同***損失的情況下，改良的網路變壓器較傳統網路變壓器可以工作在更高頻的頻帶。如圖3C~3D所示，在相同頻寬的情況下，改良的網路變壓器較傳統網路變壓器具有較低的回波損失。如第3E~3F圖所示，在相同特性阻抗的情況下（例如100±15dB），改良的網路變壓器較傳統網路變壓器具有較廣且較高的工作頻帶；另外，傳統網路變壓器的特性阻抗的偏移量大（不穩定），但改良的網路變壓器的特性阻抗的偏移量極小（很穩定）。因此，由圖3A~3F可知，根據本發明改良網路變壓器可以在不改變網路變壓器的設計模式的情況下額外增加網路變壓器的線電容，進而使得網路變壓器的特性阻抗符合一預設的特性阻抗標準。除此之外，根據本發明改良網路變壓器還可改善網路變壓器的其他屬性（例如，***損失、回波損失等等）。As shown in Figures 3A~3B, under the condition of the same insertion loss, the improved network transformer can work in a higher frequency band than the traditional network transformer. As shown in Figures 3C~3D, under the condition of the same bandwidth, the improved network transformer has lower return loss than the traditional network transformer. As shown in Figures 3E~3F, in the case of the same characteristic impedance (for example, 100±15dB), the improved network transformer has a wider and higher operating frequency band than the traditional network transformer; The offset of characteristic impedance is large (unstable), but the offset of characteristic impedance of the modified network transformer is very small (very stable). Therefore, as can be seen from FIGS. 3A to 3F , the improved network transformer according to the present invention can additionally increase the line capacitance of the network transformer without changing the design mode of the network transformer, thereby making the characteristic impedance of the network transformer conform to a preset value characteristic impedance standard. In addition to this, modifying the network transformer according to the present invention may also improve other properties of the network transformer (eg, insertion loss, return loss, etc.).
