摘要:: 针对高压大电流、低抖动高可靠工况下闸流管双脉冲触发需求，该文研制并设计一款专用预触发-主触发双脉冲触发装置，解决传统单脉冲触发导通不稳定、延迟抖动大、器件易损等问题。该装置采用高压脉冲与预电离混合触发架构，以谐振充电升压、高速MOS开关、脉冲变压器倍压与低漏感工艺实现双路脉冲协同输出，先由预触发建立稳定等离子体区，再由主触发实现快速低抖动导通，并配置负偏压及过压保护电路以提升运行可靠性。经63 kV/5000 A、3 Hz工况测试，闸流管导通电流抖动<10 ns，连续72小时运行稳定，电流波动≤±2%，触发稳定性和器件寿命显著优于传统方案。装置不改动原有结构，可实现高稳定、低抖动、长寿命触发，为高压大电流脉冲系统中闸流管可靠应用提供技术支撑。

Abstract:: In response to the dual-pulse triggering requirements of thyristors under high-voltage, high-current, low-jitter and high-reliability working conditions, this paper develops and designs a dedicated pre-trigger-main trigger dual-pulse triggering device to solve the problems of unstable conduction, large delay jitter and easy damage of components in traditional single-pulse triggering. This device adopts a hybrid triggering architecture of high-voltage pulse and pre-ionization. It achieves dual-channel pulse coordinated output through resonant charging boost, high-speed MOS switch, pulse transformer voltage doubling and low leakage inductance process. First, a stable plasma zone is established by pre-triggering, and then rapid and low-jitter conduction is achieved by the main trigger. Negative bias and overvoltage protection circuits are also configured to enhance operational reliability. After testing under 63 kV/5000 A and 3 Hz working conditions, the current jitter of the thyristor during conduction is less than 10 ns. It operates stably for 72 consecutive hours, with current fluctuations ≤ ±2%. The trigger stability and component lifespan are significantly better than those of the traditional scheme. The device does not modify the original structure and can achieve high stability, low jitter and long-life triggering, providing technical support for the reliable application of thyristors in high-voltage and high-current pulse systems.
