Impedance will reflect back as the square of the turns ratio.
阻抗将會按照匝比的平方反射回來。
The output voltage is easily set by two external resistors and the transformer turns ratio.
輸出電壓非常容易由兩個外部電阻器和變壓器匝數比設定。
Other output voltages are possible by adjusting the transformer turns ratio and value of Zener diode VR2.
其它輸出電壓是可能的,經過調整變壓器匝數比齊納二極管VR2和價值。
However, as long as I kept the turns ratio the same, the wire gauge appropriate, and the flux density similar, I thought the risk should be low.
然而,隻要我保持同樣的轉換率,適當的線規格和相似的流量密度,我認為風險就會很低。
It has been shown that a primary input voltage can be transformed to any desired open-circuit secondary voltage by a suitable choice of turns ratio.
通過選擇合適的匝數比,一次側輸入電壓可任意轉換成所希望的二次側開路電壓。
匝數比(Turns Ratio) 是變壓器設計與分析中的核心參數,定義為變壓器初級繞組(輸入側)的匝數 (N_p) 與次級繞組(輸出側)的匝數 (N_s) 之比,其數學表達式為:
$$ text{匝數比} = frac{N_p}{N_s} $$
在理想變壓器中(忽略損耗),匝數比直接決定電壓變換特性:

“turns ratio”是一個與電磁學、電氣工程相關的專業術語,通常指變壓器中的匝數比,即初級線圈與次級線圈的匝數之比。以下是詳細解釋:
電壓與電流變換
根據電磁感應定律,變壓器的輸出電壓與輸入電壓之比等于匝數比,而電流比則為匝數比的倒數。例如:
變壓器測試
在工程中,需通過專用設備(如T-203H三相變壓器變比測試儀)測量實際匝數比,确保其符合設計值,避免能量損耗或設備故障。
