impedance converter 中文意思是什麼

impedance converter 解釋
阻抗匹配變換器
  • impedance : n. 【物理學】阻抗。 acoustic impedance聲阻抗。
  • converter : n. 1. 使轉變[改變信仰]的人。2. 改裝者，改裝品。3. 【冶金】煉鋼爐，吹風轉爐；【電，無】換流器，變壓器；變頻器；【自動化】變換器；密碼翻譯[編制]機。
  1. Compare to the normal rectangular waveguide, ridge waveguide has the character of broader bandwidth, smaller dimension, lower equivalent characteristic impedance, etc. because of these merits, it is used more and more widely, such as broadband ridge waveguide filter, broadband direct coupler, diplexer, frequency converter, phase shifter, ridge waveguide slot antenna array, and so on

    與普通矩形波導相比，脊波導具有工作頻帶寬、尺寸小、等效特性阻抗低等特點。由於脊波導本身的特點，使其得到了越來越多的應用，例如寬帶脊波導濾波器、寬帶定向耦合器、雙工器、變頻器、移相器、脊波導縫隙天線陣等等。
  2. Negative impedance converter

    負阻抗變換器
  3. By selecting the voltage space vector of the voltage across the equivalent converter impedance as the control variables, the steady - state model of hvdc - vsc is developed. on this basis, a steady - state feedback linearization strategy is proposed, then, linear and decoupled control is realized using pi controllers and feedforward compensation

    建立了以vsc等效換流阻抗上的基波壓降所對應的電壓空間矢量為控制量時hvdc - vsc的穩態模型，並根據所建立的穩態模型，提出了基於穩態模型的hvdc - vsc反饋線性化控制策略。
  4. At first, the average - current controlled boost pfc and buck converter small - signal model are estabished. the average - current controlled boost pfc and buck converter prototype are designed and manufactured. on basis of the small - signal model, the two - stage i / o impedance characteristic and miller effect are analyzed by simulation with matlab software

    其次單獨設計了前級、后級變換器樣機，在兩級模型基礎上，應用matlab軟體模擬分析了前後級變換器對接處的i o阻抗特性和密勒效應，運用奈奎斯特判據對兩級結構寬輸出電壓范圍的功率因數校正器的穩定性進行了分析設計。
  5. In order to make the converter operate normally without the interference by emf, the cable connecting the converter to a 3 - phase motor must have high resistance to emf interference, low effective capacitance and low transmission impedance

    為保持變頻率器正常工作不受電磁干擾，因此連接變頻器與三相交流電機之間的電纜就要求具有抗干擾性能、較低的有效電容及較低的傳輸阻抗。
