为了探索高温超导储能用于线圈型同步感应电磁推进脉冲电源的可行性,研究了超导电感和电容混合型meat-grinder脉冲电源电路。设计并研制了一个小型的高温超导储能脉冲变压器,提出了高温超导储能脉冲变压器使用meat-grinder电路拓扑结构的脉冲成形方案,并以3个电感线圈作模拟同步感应电磁推进系统负载,进行了仿真分析和实验验证。在77 K和储能电流96 A的情况下,实验得到了2.35~3.04 kA的电流脉冲输出,并有望在20 K温度下满足线圈型电磁推进的应用要求。结果表明,提出的脉冲电源模式是可行的。因负载电流脉冲受负载阻抗影响较大,在实际电磁推进应用中,需要减小线路电阻和常导电感的内阻。
In order to explore the feasibility of high-temperature superconducting energy storage for coil synchronous induction electromagnetic propulsion pulsed power supply, the meat-grinder pulse power circuit with superconducting inductance and capacitance is studied. A small high temperature superconducting energy storage pulse transformer was designed and developed. The pulse shaping scheme of the meat-grinder circuit topology for high temperature superconducting energy storage pulse transformers was proposed. Three inductive coils were used to simulate the electromagnetic induction system load , Conducted a simulation analysis and experimental verification. The current pulse output of 2.35 ~ 3.04 kA was obtained at 77 K and 96 A of storage current, and it is expected to meet the application requirements of coil electromagnetic propulsion at 20 K. The results show that the proposed pulse power mode is feasible. Because the load current pulse is greatly affected by the load impedance, in the actual electromagnetic propulsion applications, the internal resistance of the line resistance and the sense of constant conductivity needs to be reduced.
