| 摘 要： | 研制了10 kV高压反向开关晶体管（RSD）开关组件。在重复频率0.2 Hz、峰值电流约107 kA、峰值功率约1 GW、单次传输电荷约20 C、单次传输能量约100 kJ条件下，实验次数达50 000多次；主要研究了RSD开关的静态伏安特性随实验次数的变化趋势。采用数值分析的方法，统计拟合得到了长脉冲大电流条件下RSD开关的寿命模型，并依据失效判据初步预估RSD开关的寿命可达107次。

| Abstract: | This paper presents a switch assembly based on reversely switched dynistor(RSD). The RSD-based assembly has been tested with the working voltage of 10 kV, repetition frequency of 0.2 Hz and peak current of about 107 kA. The peak power is larger than 1 GW. The transferred charge and energy per shot are about 20 C and 100 kJ, respectively, and the total experimental shot number is more than 50 000. The lifetime of RSD switch was investigated with the static volt-ampere character. The lifetime model of RSD switch under high current for long pulse application was established with numerical fitting. According to the failure criterion, the preliminarily estimated lifetime is about 107 shots. |
