摘要
小型化、轻量化和重频化是当前脉冲电源的主要发展趋势。高温超导电感储能型脉冲电源具有储能密度高、损耗小和对充电功率要求低等优点而受到研究人员的关注。其中,基于高温超导脉冲变压器储能和脉冲压缩的脉冲电源模式是重要的发展方向之一。为此针对脉冲电源的重频化发展趋势,提出了一种基于高温超导脉冲变压器的连续脉冲电源电路,理论分析了该脉冲电源电路的工作过程和主要性能影响因素,构建了3 kJ的高温超导脉冲变压器线圈仿真模型,对主要性能影响因素的理论分析方法进行了仿真验证。由仿真和理论计算结果可以看出,电流放大倍数随着副边电感的增大而减小,不过,断路开关的最大电压和最大电容储能比例也都随之降低。最后,利用小型高温超导脉冲变压器搭建了连续脉冲电源的实验电路,实现了连续电流脉冲的输出。仿真和实验结果证明了这种连续脉冲电源电路的可行性。
The main development trends of pulsed power supply are miniaturization, lightweight and repetition rate. High temperature superconducting(HTS) inductive pulsed power supply has stimulated enormous research interest of researchers because of its high energy storage density, low loss and low power requirements. High temperature superconducting pulse transformer(HTSPPT) is an important device for the HTS inductive pulsed power supply. It is usually used for energy storage and pulse compression. Aiming at the development of pulsed power supply, we proposed a pulsed power supply circuit topology for continuous current pulse operation based on HTSPPT. The working process and the critical parameters were analyzed. A 3 kJ HTSPPT coil module was constructed by using the finite element simulation,and the critical parameters calculation method was verified. The simulation and theoretical results show that although the current amplification factor decreases with the increase of the secondary inductor, the maximum voltage of the opening switch and the maximum capacitive energy storage ratio are also decreased. Finally, the experimental circuit of this continuous pulsed power supply is built by using a small HTSPPT, and the output of continuous current pulse is realized. The feasibility of this continuous pulsed power supply circuit can be proved by simulation and experiment results.
