直列式引信高压电路的升压时间决定了引信的三级解保时间,是引信全电子安全系统的关键指标。通过对引信高压电路中反激变换器的工作过程进行动态分析和建模,推导出输出电压的动态模型,揭示了升压时间的变化规律,为引信高压电路的参数优化设计和闭环控制提供指导。通过Simulink建立引信高压反激变换器的模型,通过仿真验证了动态模型的正确性和升压时间的变化规律,并通过闭环反馈控制来达到升压目标。

The boost time of the high-voltage circuit of the inline fuze determines the arming time of the fuze,which is a key indicator of the S&A system.In this paper,by modeling and dynamic analysis of the flyback converter in the high-voltage circuit of the fuze,the dynamic model of the boost was derived,revealing the variation law of boost time.It provided guidance for the parameter optimization design and closed-loop control of the high-voltage circuit of fuze.Finally,the model of the high-voltage flyback converter for the fuze was established using Simulink.The variation law of the boost time was verified through simulation,and the boost target was achieved through closed-loop feedback control.
