针对电磁发射系统的系统结构优化问题中馈电方式对系统效能的影响进行了分析，并提出了改进的系统结构。通过引入分布式馈电模式，改变轨道接入PFN放电回路的程度，降低轨道上的损耗，提高了系统效率。仿真分析表明：采用新的时序触发分布式馈电方式，相比单个放电阶段的简单系统以及基于多级电源的时序放电系统，不仅实现了安全稳定的能级跃升，并且克服了使用单个电源的分布式电流馈入方式电流衰减的问题，具有结构新颖、安全可靠、能量利用高效的特点，适合新的系统结构改进设计的要求。

T his paper analyzes the impact of different feeding‐in modes on the system performance of different structures of the electromagnetic launch system and proposes a new structure . Through changing the extent to which the payload is connected to the discharging circuit of PFN network ,the resi‐dual magnetic energy of the payload inductance and the resistive energy loss can be reduced ,and the system efficiency can be raised .Simulations show that the new structure w hich can not only cause a safety and stable rise in energy level but also overcome the current attenuation of the DCF (distributed‐current‐feed) is characterized by novelty ,good reliability and high efficiency thus to meet the requirements of optimal design of the electromagnetic launch system .
