2017年6月22日 · Abstract: The results of research of heavy pulse current switches built on Light Triggered Thyristors (LTT) and pulsed diodes are presented. Transients in a semi-conductor switch are analyzed at a capacitor discharge in a Pulse Forming Network (PFN), which incorporates an inductor and crowbar diodes.

The design of the switch unit for the capacitive energy storage comprising LTTs and crowbar diodes is described, and the transient processes of current switching in crowbar diodes are considered. The tests carried out during switching of pu1se current up to 100 kA at a voltage of 6 kV have confirmed the workability of the switch unit.

Abstract: High-voltage high-power pulse switches are built with semiconductor devices, preferably thyristor, due to the superior performance that they offer. Triggering methods classify the thyristor as electrically triggered thyristor (ETT) and light triggered thyristor (LTT).

2018年10月1日 · The purpose of the present study is to analyze the operation features and permissible modes of LTT as a discharge current switch of the capacitive energy storage, as well as to discuss the design of the semiconductor switch composed of LTTs and crowbar diodes for pulse currents up to 100 kA.

Switch OLED通过升级屏幕、音响和底座，提升了桌面模式和掌上模式的游戏体验，但是对于电视模式游戏体验的改进并不明显。 从推荐度上来说，Switch长续航版＞Switch OLED版＞Switch Lite。

2021年6月14日 · 在利用LTspice仿真时，Voltage Controlled Switches（电压控制型开关）能够简化我们的仿真 模型，提高仿真效率，从命名我们知道它是一个由电压控制的开关，下面将详细介绍它的用法！ 一、哪里找到它？ 故上述模型的语法定义意思为：当阈值电压为0.5V时SW的阻抗为1欧姆，其余情况为1兆欧姆。 在模型的语法定义中增加 level=2 oneway 语句，此时SW具备单相导通性，即便V1在导通电压范围内（大于0.5V）当V2的电压为负时SW仍然呈现出高阻抗性， …

The process of OFF-ON switching of LTTs has been investigated, the necessity is shown to use the speed-up R-C circuits to ensure fast and stable transition of LTT into the conducting state. The design of the switch unit for the capacitive energy storage comprising LTTs and crowbar diodes is described, and the transient processes of current ...

LTT’s Modular Switch Mounts work in conjunction with LTT Heat Shields to integrate weapon light remote switches onto your defensive shotgun. The Modular Switch Mounts are completely ambidextrous, low profile, and can be repositioned along the forend of the shotgun to suit a wide range of shooters and techniques.
