脉冲磁场作为一种优秀的激励源，可应用于许多材料性质的无损检测技术中，以提供瞬态电磁测试条件。在国际热核聚变实验堆(ITER)项目中，为了测试实验包层模块(TBM)材料的瞬态电磁性能，需要设计研制上升时间约为3 ms，磁感应强度可达0.8 T的脉冲磁场产生系统。首先，理论分析了脉冲磁场产生的原理，依据实验设备条件确定了系统各个参数，使系统能达到该测试项目的要求。其次，搭建了脉冲磁场产生系统，包括充放电电路、螺线管、工控系统、磁场测试系统、真空系统和数据采集处理系统。最后，对脉冲磁场产生系统进行了测试，并分析了影响系统的因素。测试结果显示，该系统产生的脉冲磁场，能够满足瞬态电磁测试项目的需要。

As a good excitation source to generate a transient electromagnetic testing condition, the pulsed magnetic field has been applied in many non-destructive testing techniques for property characteristic of varies materials. In International Thermonuclear Experimental Reactor (ITER) program, to test the transient electromagnetic property of test blanket module (TBM) material, a pulsed magnetic field generation system is needed, whose rise time is about 3 ms and magnetic induction can be up to 0.8 T. In this paper, the mechanism of the pulsed magnetic field generation system is theoretically analyzed. In the experiment, the parameters of the system were set to meet the demands of the test program and a pulsed magnetic field generation system was set up, which included a charge-discharge circuit, a solenoid, an industrial control system, magnetic field test system, a vacuum system, and a data sampling and processing system. The pulsed magnetic field generation system was tested and the factors affected the system were analyzed. The result shows that the system can generate a qualified pulsed magnetic field for the transient electromagnetic test program.
