轻小型脉冲电源驱动的电磁发射系统建模

Modeling of electromagnetic launch system driven by CPA

针对脉冲电容器储能密度过低的问题，首先提出了一种基于轻小型脉冲电源（补偿脉冲发电机）驱动的电磁发射系统设计方案；然后，在分析了系统的基本原理的基础上，分别从电路模型、运动学模型出发建立了该电磁发射系统的数学模型；最后，通过算例进行了计算分析，其结果验证了系统数学模型的正确性，也表明以补偿脉冲发电机作为电磁轨道炮的脉冲电源是可行的。

Aiming at the problem that energy storage density of pulse capacitor is too low, a new de- sign scheme of the electromagnetic launch system which is driven by compensated pulsed alternator （CPA） is proposed. Based on analysis of fundamental principles of the system, the mathematical mod- els of the EML system including circuit model and motion model are respectively established. In the end, a calculation example is given to prove the correctness of the mathematical model. The results show that the design scheme tb, at using the CPA as pulsed power supply for electromagnetic launch system is feasible.
