The anode structure of CI-LIGBT is optimized by numerical simulation, and it is pointed out that segmented p〓 anode region surrounded by n〓 anode region is the key to improve the ability of current limiting, and the more deeper the n〓 anode junction relative to the p〓 anode junction, the more powerful the ability of current limiting is. The affection of the breakdown voltage BV〓 of the reverse biased p〓n〓 junction and the sample resistance upon the latching current, the latching voltage and the on-state voltage have been studied, and it is indicated that the tradeoff between the on-state voltage and the latching characteristics is the excellentest when BV〓 is 1. 1V so that its on-state voltage can be just only 0.6V higher than conventional LIGBT. It is also found that this device is especially suit to high temperature environment. Based on X. B. Chen's surface voltage sustaining structure using optimized variational lateral doping and Ludikhuize's multiple floating rings structure, high voltage LIGBT and is studied in this paper.

通过数值模拟，优化了CI-LIGBT的阳极区结构，指出采用被n〓阳极区包围的单元状p〓阳极区是提高该器件限流能力的关键，而n〓阳极区结深相对p〓阳极区结深越大，器件的限流能力越强；分析了反偏p〓n〓结击穿电压BV〓和取样电阻对器件闩锁电压、闩锁电流和导通压降的影响，得出BV〓在1.1V时器件导通压降和抗闩锁能力间的折衷关系最优，其导通压降仅比普通LIGBT高0.6V；分析了温度对LIGBT闩锁性能的影响，表明CI-LIGBT即使在450K的高温下也不会闩锁，尤其适用于高温工作环境。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
