研究设计了一种可用于触发反向触发晶闸管(RSD)的电路。给出了通过参数寻优选取触发电路参数的思路。初步试验中发现存在主脉冲波形畸变和续流拖尾问题，提出了对典型谐振触发电路的两点改进：提出了基于可饱和磁介质环的触发脉冲整形方法，解决了主脉冲波形畸变问题；通过串联阻容回路吸收剩余触发能量，消除了脉冲的续流拖尾。试验结果显示RSD开通特性良好，表明所设计的触发电路能满足开通μs级高上升率电流脉冲的需求。

The paper presents a resonant triggering circuit for driving high power reverse switched-on dynistor(RSD). The method for choosing the circuit parameters by optimization is proposed. Owing to the deformation and tail current of the current pulse found in preliminary experiments, two improvements are adopted in the circuit. First, a saturable magnetic ring is utilized to smooth the triggering current pulse. Secondly, a resistance-capacitor circuit is designed to absorb the redundant triggering energy. The experimental results show that the improved triggering circuit can offer an excellent triggering and conducting characteristic for RSD devices.
