摘　　要：面向重频快速电磁发射的应用需求,针对其对混合储能系统初级储能向次级储能超高频率充电的难题,提出了一种基于“超级电容-脉冲电容”的新型混合储能系统,与现有“蓄电池-脉冲电容”混合储能相比,该系统具有快速充电和长寿命的优势。首先,在介绍该储能系统基本电路结构和原理的基础上,结合时序串联充电方式推导了其内部能量转移过程的理论模型;然后,基于Matlab仿真平台搭建系统仿真模型,给出了时序串联充电控制策略,以及充电电压和电流波形,并定量分析了回路阻抗对充电波形的影响。仿真结果表明:所提出的基于“超级电容-脉冲电容”的混合储能系统可实现数十发/分的射速,可为重频速射电磁发射的应用提供有效的能源供给方案,且该混合储能系统基于时序串联控制可实现对电磁发射脉冲电源电压的精准控制。In response to the application requirements of repetitively electromagnetic launch,a new hybrid energy storage system was proposed based on"supercapacitor-pulse capacitor"to address the challenge of ultra-high frequency charging from primary energy storage to secondary energy storage in hybrid energy storage systems.Compared with the current"battery-pulse capacitor"hybrid energy storage system,it has advantages of fast charging and long life.While introducing the basic circuit structure and principle of the hybrid energy storage system,the theoretical model of its internal energy transfer process was derived in series charging method.A system simulation model was built based on the Matlab simulation platform and the control strategy for series charging,as well as the charging voltage and current waveforms,was simulated.The impact of circuit impedance on the charging waveform was quantitatively analyzed.The simulation results show that the proposed hybrid energy storage system based on"supercapacitors-pulse capacitors"can achieve a firing rate of tens of rounds per minute,and thus providing an effective energy supply solution for the application of repetitively electromagnetic launch.Moreover,the hybrid energy storage system can achieve precise control of voltage based on series-charging control.
