建立了串联充电-并联放电型电感储能单级脉冲感应线圈炮的系统模型,利用PSpice对系统特性进行了仿真,分析了弹丸线圈时间常数、转换电容、初始位移等参数对发射过程的影响,并对比了单个电感线圈储能和两个电感线圈串联充电-并联放电型电源拓扑的发射结果。搭建了由两个电感线圈构成的串联充电-并联放电的小型线圈炮实验系统,其中控制电路以DSP芯片TMS320F2812为基础设计而成。实验结果和仿真结果吻合较好,验证了系统模型的正确性。

Serial-charge-parallel-discharge inductive energy supply for coilgun system

A model of the serial-charge-parallel-discharge inductive energy supply for the single stage pulsed inductive coilgun system was set up in this paper.The performance of the system was simulated with PSpice.The influences of the time constant of the projectile coil,the transfer capacitor,and the initial displacement of the projectile coil to the launch process were analyzed using the simulation platform and some important conclusions for the coilgun design were obtained based on the above analysis.In addition,some key parameters in the launch process were compared between the topology with one energy storage coil and the topology with two serial-charge-parallel-discharge energy storage coils.An experiment was carried out based on the laboratory-level system,which contained two serial-charge-parallel-discharge energy storage coils.The experimental results coincided with the simulations,which verified the correctness of the equivalent model.In the experiment,the control system was designed based on the DSP TMS320F2812.The simulations,the analysis and the experiment provided instructive data and experience for the future research on both the coilgun system design and the serial-charge-parallel-discharge inductive energy supply.
