Problems with high on-resistance that are seen in traditional vertical structure DMOSFET still appear in LDMOSFET and phenomena of turn-off delay and latch-up are seen in LIGBT as well. 传统垂直式DMOSFET高导通电阻的缺点在LDMOSFET中依旧存在,而垂直式IGBT关闭延迟和闩锁的现象,也在LIGBT中发生。
To analyze the reason of the three-stage engine turn-off delay of some liquid rocket engine, the stable state fault module of the engine was established in this paper. 为分析某液体火箭三子级发动机推迟关机的原因,建立了发动机稳态故障的模型。
By using the disordered resistance to counteract the turn-off delay, the fast shutdown of the Synchronous Transistor will be realized and the probability of the current back flow will be reduced. 6. 该电路利用失调电阻抵消同步管关断延迟,达到了快速关断同步管的目的,有效的减小了电流倒灌现象的发生。
