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。

It is thought that the channel bay line evolution processes can be divided into four stages. The first stage is soon of the sea level stable when the bayhead mountines are eroded and developed abrasion geomorphy and the productive materials were transport into the bay deposition by the tidal current and wave current and were reworked into gravel dams. The second stage is characterized by the fluvial output sediments and eroded sediments mixed deposition in channel bay and developed marine accumulation plain and sand riges in the plain under the wave reworked. The third stage developed clay silt marine accumulation plain under the action of the channel current and the wave action is very limited. The fourth stage is marked by human being reclaim which result in the channel bay filled and evoluted into a strait arce coast.

文章认为，峡道海湾的充填经历了四个阶段，第一阶段以峡道海湾湾顶山体在波浪作用下产生的侵蚀物质充填为主，发育了海蚀崖、海蚀洞、海蚀穴等侵蚀地形和湾顶砂砾石堤等堆积地形交替的峡道湾顶地貌，第二阶段以河流输出物质和峡道湾岛屿、礁石侵蚀物质在潮流作用下向峡道湾输运，由潮流和波流共同沉积为特征，发育海积平原，部分粗颗粒泥沙在波浪的改造峡，发育平原沙堤，第三阶段以河流输出物质为主，在涨落潮流搬运下进入峡道和峡道湾沉积，在峡道湾中发育以淤泥质粉砂为主要物质的海积平原，第四阶段以人类围涂造田为标志，加速峡道湾的充填过程，使峡道海湾最终趋于夷平，形成顺直均衡的弧形海岸。

That is, the motor winding capacitance in series with the Deputy, due to the role of the capacitor, so that Kim winding current phase ahead of the main winding current in phase 90 °, in accordance with the basic theory of motor learning: When the space two winding axis position is 90 °, and the flow of two windings of the current phase and poor 90 °, its synthesis must be for the rotating magnetic field, magnetic field, so that motor up and running.
