摘要 电磁轨道炮用脉冲功率电源模块多采用耐高压、耐大脉冲电流冲击的晶闸管作为脉冲电容器的放电主开关,以尽可能地减少体积,提高储能密度。现有文献针对晶闸管的动态开通过程已进行过大量研究,主要致力于提高晶闸管电路模型的准确性。该文针对一种由脉冲电容器放电主回路高频谐振引起的晶闸管开通过程电压振荡现象,首先根据真实的实验电路结构研究振荡产生的机理;进而通过电路仿真验证理论分析的正确性;最后提出消除电压振荡的方案并完成实验验证。相关研究结论对优化电磁轨道炮用脉冲功率源具有一定的现实意义。

Abstract:For pulsed power supply module of an electromagnetic railgun system, thyristors that have the excellent ability to withstand high voltage and high pulse current is always selected as the pulse discharging switch to reduce the volume and improve energy storage density. Existing literatures have extensively researched the dynamic opening process of thyristor and improved the accuracy of thyristor equivalent circuit model. This paper studied a special voltage oscillation phenomenon caused by high frequency resonance in main circuit during pulse capacitor discharge. Firstly, the mechanism of the voltage oscillation was studied according to the configuration of the main circuit. Further, circuit simulation was carried out to verify the correctness of the theoretical analysis above. Finally, a feasible method was proposed to eliminate the voltage oscillation. The related conclusions in this paper have certain practical significance for optimizing the pulsed power module used in electromagnetic railgun system.
