| 摘要: |
| 用于脉冲功率电源的高温超导脉冲变压器，集超导储能与脉冲放电为一体，在脉冲功率技术中有着良好的发展前景。设置合理的线圈结构参数可以提升高温超导脉冲功率变压器的耦合系数和储能容量，满足脉冲功率电源小型化、轻量化的优化目标。本文利用有限元仿真软件Anysys EM，建立了同轴饼式线圈叠加结构的单模块变压器模型和环形结构的多模块变压器模型，根据磁场分布和后期计算，分析了结构参数对脉冲变压器耦合系数和原边超导线圈的储能的影响。仿真分析结果表明，在77 K时，采用相同用线量的情况下，单模块高温超导脉冲变压器耦合系数和原边电感线圈的储能随线圈高度减小逐渐增大；多模块高温超导脉冲变压器减小线圈高度、增大内半径能够获得较高的性能，为超导脉冲变压器的脉冲电源实验验证提供了一定的参考依据。 |

| Abstract: |
| High temperature superconducting pulse power transformer (HTSPPT) for pulse power supply can store superconducting energy and amplify pulse. It has a good development prospect in pulse power technology. Proper coil structure parameters can increase the coupling coefficient and energy storage capacity of HTSPPT. This can meet the optimization goal of miniaturization and lightweight of pulse power supply. In this paper, the finite element simulation software Anysys EM is used to establish the simulation model of single module transformer with coaxial pancake coil structure and multi-module transformer with ring structure. According to the magnetic field distribution and calculation, the influence of structural parameters on the performance of pulse transformer is analyzed. At 77 K, in the case of the same amount of wire, the high-temperature superconducting pulse transformer of the single-module coaxial cake structure, the coupling coefficient and the energy storage of the primary-side inductor coil gradually increase with the decrease of the coil height; The high-temperature superconducting pulse transformer with multi-module ring structure can reduce the coil height and increase the inner radius to obtain higher performance, which provides a reference for the experimental verification of pulse power supply of multi-module pulse transformer. |
