fast-recovery diode 中文意思是什麼
fast-recovery diode
解釋
快速回復二極體-
Power fast recovery diode, which is abbreviated to frd, is one of the key devices in modern power electronic technology. in the power electronic circuits, frd is usually parallel connected with three - end power devices as their freewheeling diode
高壓功率快恢復二極體（以下簡稱frd ）廣泛地應用於電力電子電路中，作為續流二極體與三端功率器件並聯使用，是現代電力電子技術中的關鍵器件。 -
On the base of the study on sige material physics characteristic, sige / si hetero - junction characteristic, we dissertate the advantage of sige / si hetero - junction power diodes and establish more accurately physical models and propose two novel kinds of fast and soft recovery p + ( sige ) - n - - n + hetero - junction power diodes : the one is p + ( sige ) - n " - n + diode with the multiplayer gradual changing doping concentration in the n - region, and the other is p + ( sige ) - n " - n + diode with ideal ohmic contact on the cathode interface
本文針對sige材料的物理特性、 sige si異質結特性建立了準確的物理參數模型。在詳細論述了sige si異質結功率二極體良好特性的基礎上，提出了兩種快速軟恢復sige si功率二極體新結構： n ~ -區採用多層漸變摻雜和陰極側採用理想歐姆接觸。 -
The researching results indicate that using the two kinds of novel structure, the fast - switching and the soft recovery characteristics of the device are much improved but not notable changed in forward drop, and the temperature characteristic is improved, too. most of the characteristics are far better than the normal pin diode structures
研究結果表明，在採用?基區漸變摻雜和臺面結構后的p ~ + （ sige ） - n ~ - - n ~ +異質結中，我們得到了更快而軟的反向恢復特性，和更低通態壓降的正向導通特性，且溫度特性也有明顯改善。 -
