Circuit topology optimization and performance improvement of magnetic resistance coil launcher

  • 摘要: 为提高线圈发射器的发射速度及能量利用率,研究了磁阻型电磁线圈发射器不同放电电路结构对发射性能的影响。对晶闸管式(SCR)、半桥式、阻容(RCD)吸收式、Boost-Buck式四种不同结构放电电路进行分析,使用有限元方法研究了四种电路对发射性能的影响。结果表明,相同条件下,相比SCR式电路,三种可关断电路中,Boost-Buck式电路下电枢出口速度提升最少,为78.77%;RCD式电路下系统能量利用率提升最少,为220.66%。可关断电路中电流的衰减速率会影响电枢的加速度,存在最优电流衰减速率曲线;单级可关断电路中出口速度与系统能量利用率搭配最均衡的为半桥式放电电路;Boost-Buck式放电电路更具灵活性,更适合应用于多级线圈发射器中。
