针对轨道炮的应用需求,为解决电感储能型脉冲电源炮口消弧与剩余能量回收的问题,在绞肉机电路基础上提出了一种新型超导储能脉冲电源拓扑。建立了脉冲电源与简单轨道炮的仿真模型,仿真实现了轨道电流在电枢出炮口前降为0的设计并进行了能量回收,分析了电容参数和终止放电时机对系统性能的影响。仿真与实验结果表明:该拓扑可以实现充电、放电、终止放电、能量回收4种工作模态;在充电电流16.5 A的条件下,最终输出的脉冲电流峰值达到了166 A,而且在放电过程后,回收了部分能量,回馈电流为11.2 A,这减少了系统45.78%的能量损耗;电容参数的设计应同时考虑对系统电压应力和脉冲电流波形的要求,终止放电时机应在考虑延时的前提下尽量后移。
Aimed at the application requirements of rail gun, a new type of superconducting energy storage pulse power topology was proposed on the basis of meat grinder circuit in order to solve the problem of arc extinguishing and residual energy recovery in muzzle discharge of inductive energy storage pulse power supply. A simulation model of pulse power supply and simple rail gun was established. The design of the rail current at the front of the muzzle of the armature and its energy recovery were simulated and the influence of the capacitor parameters and the timing of the termination discharge on the system performance was analyzed. Simulation and experimental results show that the topology can achieve four working modes of charging, discharging, termination discharge and energy recovery. At the charging current of 16.5 A, the pulse current peak output finally reaches 166 A, and after the discharging process , Part of the energy recovery, the feedback current of 11.2 A, which reduces the system 45.78% of the energy loss; capacitance parameter design should also consider the system voltage stress and pulse current waveform requirements, termination of discharge timing should consider the premise of delay Try to move backward.
