摘　　要：针对引信中电雷管点火高压电源动态升压过程与终点不清晰的问题,提出了一种以电路平均法为主要思路的建模方法,推导出了时域稳态建立的模型,设计了相应的反激变换器作为主体的高压电源电路,并进行测试。测试结果表明:建立的模型与相关分析方法能很大程度上反映直流高压输出的稳态建立过程,对相关设计具有指导意义和参考价值,可为高压电源相关研究提供理论支撑。A modeling method based on circuit averaging method was proposed,and the model of time-domain steady state was deduced,and the corresponding flyback converter was designed as the main body of high voltage power supply circuit and tested,aiming at the problem that the dynamic booster process and end point of electric detonator ignition high voltage power supply in fuze are not clear at present.The results show that the modeling and correlation analysis method can reflect the steady state establishment process of DC high voltage output to a great extent,which has guiding significance and reference value for the related design,and provides theoretical support for the research of high voltage power supply.
