而該一次側漏電感Lpl及該二次側漏電感Lsl的設置位置卻導致了上述的變壓器模擬電路在分析的過程中常有錯誤的產生。 The setting position of the primary side leakage inductance Lpl and the secondary side leakage inductance Lsl causes the above-mentioned transformer analog circuit to often have an error in the analysis process.
舉例來說，請參閱圖21所示，係繪製了透過量測獲得的一變壓器的一次側阻抗頻率響應圖以及透過計算獲得的模擬該變壓器的一變壓器模擬電路的一次側阻抗頻率響應圖。當中該變壓器的一次側阻抗頻率響應圖係在圖21中以實線Lp[P1S3]表示，而該變壓器模擬電路的一次側阻抗頻率響應圖係在圖21中以虛線Lp[MOD1,P1S3]表示。 For example, referring to FIG. 21, a primary side impedance frequency response diagram of a transformer obtained by measurement and a primary side impedance frequency response diagram of a transformer analog circuit simulating the transformer obtained by calculation are plotted. The primary side impedance frequency response diagram of the transformer is represented by a solid line Lp[P1S3] in FIG. 21, and the primary side impedance frequency response diagram of the transformer analog circuit is indicated by a broken line Lp[MOD1, P1S3] in FIG. .
在該變壓器的一次側阻抗的第一個自諧振點f1s係與該變壓器模擬電路的一次側阻抗的第一個自諧振點f1s’的頻率相近。其中該變壓器的第一個自諧振點f1s係一極點，且該變壓器模擬電路的第一個自諧振點f1s’亦為一極點。 The first self-resonance point f1s of the primary side impedance of the transformer is close to the frequency of the first self-resonance point f1s' of the primary side impedance of the transformer analog circuit. The first self-resonance point f1s of the transformer is a pole, and the first self-resonance point f1s' of the transformer analog circuit is also a pole.
但在該變壓器的一次側阻抗的第二個自諧振點f2s卻與該變壓器模擬電路的一次側阻抗的第二個自諧振點f2s’的頻率相去甚遠。其中該變壓器的一次側阻抗的第二個自諧振點f2s係一零點，且該變壓器模擬電路的一次側阻抗的第二個自諧振點f2s’亦為一零點。 However, the second self-resonant point f2s at the primary side impedance of the transformer is far from the frequency of the second self-resonant point f2s' of the primary side impedance of the transformer analog circuit. The second self-resonance point f2s of the primary side impedance of the transformer is a zero point, and the second self-resonance point f2s' of the primary side impedance of the transformer analog circuit is also a zero point.
而該變壓器的一次側阻抗的第二個自諧振點f2s與該變壓器模擬電路的一次側阻抗的第二個自諧振點f2s’之間的頻率差異係因為該變壓器模擬電路中設置有該二次側內部線圈電容Cs，且該二次側內部線圈電容Cs係等同與該一次側內部線圈電容Cp並聯，導致整體電容性阻抗的增加，進一步使得該變壓器模擬電路的一次側阻抗的第二個自諧振點f2s’的頻率降低。 The frequency difference between the second self-resonance point f2s of the primary side impedance of the transformer and the second self-resonance point f2s' of the primary side impedance of the transformer analog circuit is because the secondary is set in the transformer analog circuit The side internal coil capacitor Cs, and the secondary side internal coil capacitor Cs is equivalent to the primary side internal coil capacitor Cp in parallel, resulting in an increase in the overall capacitive impedance, further making the second side impedance of the transformer analog circuit The frequency of the resonance point f2s' is lowered.
此外，請參閱圖22所示，係繪製了透過量測獲得的一變壓器的一次側漏阻抗的頻率響應圖以及透過計算獲得的模擬該變壓器的一變壓器模擬電路的一次側漏阻抗的頻率響應圖。當中該變壓器的一次側漏阻抗的頻率響應 圖係在圖22中以實線Lpl[P1S3]表示，而該變壓器模擬電路的一次側漏阻抗的頻率響應圖係在圖22中以虛線Lpl[MOD1,P1S3]表示。 In addition, referring to FIG. 22, the frequency response diagram of the primary side leakage impedance of a transformer obtained by the measurement and the frequency response diagram of the primary side leakage impedance of a transformer analog circuit simulating the transformer obtained by the calculation are plotted. . The frequency response of the primary side leakage impedance of the transformer The figure is represented by a solid line Lpl [P1S3] in Fig. 22, and the frequency response diagram of the primary side leakage impedance of the transformer analog circuit is indicated by a broken line Lpl [MOD1, P1S3] in Fig. 22 .
在該變壓器的一次側漏阻抗的第一個自諧振點f3s係與該變壓器模擬電路的一次側漏阻抗的第一個自諧振點f3s’的頻率不同。其中該變壓器的第一個自諧振點f3s係一極點，且該變壓器模擬電路的第一個自諧振點f3s’亦為一極點。 The first self-resonant point f3s of the primary side leakage impedance of the transformer is different from the frequency of the first self-resonant point f3s' of the primary side leakage impedance of the transformer analog circuit. The first self-resonance point f3s of the transformer is a pole, and the first self-resonance point f3s' of the transformer analog circuit is also a pole.
且在該變壓器的一次側漏阻抗的第二個自諧振點(圖未示)卻與該變壓器模擬電路的一次側漏阻抗的第二個自諧振點f4s’的頻率亦不相同。其中該變壓器的一次側漏阻抗的第二個自諧振點係一零點，且該變壓器模擬電路的一次側漏阻抗的第二個自諧振點f4s’亦為一零點。 The second self-resonant point (not shown) of the primary side leakage impedance of the transformer is also different from the frequency of the second self-resonant point f4s' of the primary side leakage impedance of the transformer analog circuit. The second self-resonant point of the primary side leakage impedance of the transformer is zero, and the second self-resonant point f4s' of the primary side leakage impedance of the transformer analog circuit is also a zero point.
而該變壓器的一次側漏阻抗的第二個自諧振點與該變壓器模擬電路的一次側漏阻抗的第二個自諧振點f4s’之間的頻率差異係因為該變壓器模擬電路中設置有相互串聯的該一次側漏電感Lpl及該磁化電感Lp，導致整體電感性阻抗增加，進一步使得該變壓器模擬電路的一次側漏阻抗的第二個自諧振點f4s’的頻率降低。 The frequency difference between the second self-resonance point of the primary side leakage impedance of the transformer and the second self-resonant point f4s' of the primary side leakage impedance of the transformer analog circuit is because the transformer analog circuit is provided in series with each other. The primary side leakage inductance Lpl and the magnetizing inductance Lp cause an increase in the overall inductive impedance, further reducing the frequency of the second self-resonant point f4s' of the primary side leakage impedance of the transformer analog circuit.
因為該一次側漏電感Lpl及該磁化電感Lp造成了該變壓器模擬電路的一次側漏阻抗的第二個自諧振點f4s’的錯誤產生，而無法準確的模擬實際的變壓器的一次側漏阻抗。因此該變壓器模擬電路勢必要做進一步的改良。 Since the primary side leakage inductance Lpl and the magnetizing inductance Lp cause an error of the second self-resonant point f4s' of the primary side leakage impedance of the transformer analog circuit, the primary side leakage impedance of the actual transformer cannot be accurately simulated. Therefore, the transformer analog circuit is necessary to make further improvements.

本發明的一次側漏電感模組及二次側漏電感模組係用來表示該一次側線圈與該二次側線圈未完全耦合時而洩漏的電感性阻抗以及漏磁通量。該漏磁通量係表示該一次側線圈產生的磁通量與該二次側線圈感應生成的磁通量差值。 The primary side leakage inductance module and the secondary side leakage inductance module of the present invention are used to indicate the inductive impedance and leakage magnetic flux leakage when the primary side coil and the secondary side coil are not fully coupled. The leakage flux indicates the difference between the magnetic flux generated by the primary side coil and the magnetic flux induced by the secondary side coil.
無論該二次側線圈與該一次側線圈耦合程度如何，該一次側線圈產生的磁通量並不會因此而改變。但當該二次側線圈越反抗該一次側線圈產生的磁通量，即該二次側線圈與該一次側線圈的耦合程度越低時，該漏磁通量的大小便會越高。此外，減少該一次側線圈產生的磁通量大小可使該一次側線圈與該二次側線圈的耦合程度越高。 Regardless of the degree of coupling of the secondary side coil to the primary side coil, the magnetic flux generated by the primary side coil does not change accordingly. However, when the secondary side coil is more resistant to the magnetic flux generated by the primary side coil, that is, the lower the degree of coupling between the secondary side coil and the primary side coil, the magnitude of the leakage magnetic flux is higher. Further, reducing the magnitude of the magnetic flux generated by the primary side coil can increase the degree of coupling between the primary side coil and the secondary side coil.
因此，本發明重新設計了習用的變壓器模擬電路，且本發明的變壓器模擬電路所模擬出的頻率響應能與實際變壓器的頻率響應更相似，如此一來，便可準確地模擬實際變壓器的頻率響應，提供廠商在量產變壓器前能更準確得利用電腦軟體分析變壓器的各種數值，提早確認變壓器的品質好壞。 Therefore, the present invention redesigns a conventional transformer analog circuit, and the frequency response of the transformer analog circuit of the present invention can be more similar to the frequency response of the actual transformer, so that the frequency response of the actual transformer can be accurately simulated.

該一次側漏電感模組及該二次側漏電感模組係用來表示該一次側線圈與該二次側線圈未完全耦合時而洩漏的電感性阻抗以及漏磁通量。 The primary side leakage inductance module and the secondary side leakage inductance module are used to indicate an inductive impedance and a leakage magnetic flux that are leaked when the primary side coil and the secondary side coil are not fully coupled.
該漏磁通量係表示該一次側線圈產Wp生的磁通量與該二次側線圈Ws感應生成的磁通量差值 The leakage flux is a difference between the magnetic flux generated by the primary side coil and the magnetic flux induced by the secondary side coil Ws.
無論該二次側線圈Ws與該一次側線圈Wp耦合程度如何，該一次側線圈Wp產生的磁通量並不會因此而改變。但當該二次側線圈Ws越反抗該一次側線圈Wp產生的磁通量，即該二次側線圈Ws與該一次側線圈Wp的耦合程度越低時，該漏磁通量的大小便會越高。此外，減少該一次側線圈Wp產生的磁通量大小可使該一次側線圈Wp與該二次側線圈Ws的耦合程度越高。 Regardless of the degree of coupling of the secondary side coil Ws with the primary side coil Wp, the magnetic flux generated by the primary side coil Wp does not change accordingly. However, when the secondary side coil Ws is more resistant to the magnetic flux generated by the primary side coil Wp, that is, the lower the degree of coupling between the secondary side coil Ws and the primary side coil Wp, the magnitude of the leakage magnetic flux is higher. Further, reducing the magnitude of the magnetic flux generated by the primary side coil Wp can increase the degree of coupling between the primary side coil Wp and the secondary side coil Ws.
