Novel method for calculating the switching torque of high-pressure wellhead gate valve

高压井口闸阀开关扭矩计算新方法

The spatio-temporal profile of sample plug can be well controlled in the analysis channel by switching virtual gate in a proper mode and timing.

通过控制虚拟门的打开方式和时机，可以控制样品注入分析通道的时空分布。

In this prescaler, no glitch generate at switching, due to the change of switching order. And nor gate is introduced in phase-switching-control circuit to avoid the generation of extra pulse completely.

本预分频器通过改变相位切换电路中的切换顺序，完全避免了切换产生的错误毛刺的产生；切换控制电路中采用或非门产生相位切换控制信号，有效防止了多余脉冲的产生。

Combined p type diverter with double gate control, this device has the function of shunt flowing of hole current, so, further improvements of the FBSOA and switching capability of EST are obtained.

该p型转向器（diverter）与双门极的结合使得空穴电流分流，从而明显改善了传统EST的正向偏置安全工作区（FBSOA），提高了其开关能力。

And the analysis is made on gate characteristics and switching process of IGBT.
