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。To improve the muzzle speed and energy utilization of the coil launcher,this article studies the impact of different circuit topology structures of the magnetic resistance electromagnetic coil launcher to improve the performance.Four topology structures,including silicon controlled rectifier(SCR)type,half-bridge type,resistor capacitor diode(RCD)absorption type,and boost-buck type,are analyzed,and the influence of different topology on the performance is studied by finite element method.The results show that under the same conditions,compared with the SCR circuit,among the three switchable circuits,the boost-buck circuit has the least increase in armature muzzle speed,which is 78.77%;the RCD circuit has the least increase in system energy utilization,which is 220.66%.The attenuation rate of the current in the turn-off circuit will affect the acceleration of the armature,and there is an optimal current attenuation rate curve.The one with the most balanced combination of muzzle speed and system energy utilization in the single-stage turn-off circuits is the half-bridge discharge circuit;boost-buck discharge circuit is more flexible and suitable for use in multi-stage coil launcher.
