Due to the low electrical losses and low charging power requirements, the application of superconducting inductors in the inductive pulsed power supply (IPPS) for Electromagnetic Launch (EML) has great potential. In our previous studies, a repetitive IPPS circuit was proposed based on a high temperature superconducting pulsed power transformer (HTSPPT), which can recover the residual energy of the secondary circuit after each discharging phase and generate repetitive current pulses. However, when the load is an inductive load, such as augmented rail-type EML, the recovery process of residual energy will slow down. On this issue, this paper proposes a new repetitive IPPS circuit with residual energy rapid recovery branch. The remaining energy of the inductive load can be recovered by the capacitor in the proposed branch and can be provided to the load again in the next discharging phase. Simulations are carried out to illustrate this circuit. The results show that the proposed circuit has advantages in improving the amplitude of the output current pulse, shortening the fall time of the load current, and improving the effective energy utilization efficiency of the system.

一种新型余能快速恢复支路重复感应脉冲电源电路

由于低电损耗和低充电功率要求，超导电感器在用于电磁发射（EML）的感应脉冲电源（IPPS）中的应用具有巨大潜力。在我们之前的研究中，提出了一种基于高温超导脉冲功率变压器（HTSPPT）的重复IPPS电路，它可以在每个放电阶段后回收二次电路的剩余能量并产生重复的电流脉冲。但是，当负载为感性负载时，例如增强型轨道式EML，剩余能量的回收过程会变慢。针对这个问题，本文提出了一种新的带有剩余能量快速回收支路的重复IPPS电路。感性负载的剩余能量可以由建议分支中的电容器回收，并且可以在下一个放电阶段再次提供给负载。进行仿真以说明该电路。结果表明，该电路在提高输出电流脉冲幅度、缩短负载电流下降时间、提高系统有效能量利用效率等方面具有优势。
