| 摘 要： | 基于工频或高频磁化条件下磁芯的测试数据不能准确反映磁芯在单次脉冲磁化下的性能,给出了一种脉冲磁化条件下磁芯性能的测试方法和数据处理方法，实验研究了快脉冲磁化条件下非晶态合金磁芯的损耗特性，磁芯最短饱和时间67 ns，最大磁化速率达到40 T/s。通过数据处理，给出了磁芯损耗与磁化速率的关系曲线，获得了不同磁化速率下磁芯的损耗数据。分析了脉冲磁化条件下涡流损耗和磁滞损耗所占的比例。研究结果表明:脉冲磁化条件下非晶态合金磁芯损耗与磁化速率关系符合饱和波模型，磁芯损耗随磁化速率增大而线性增大。

| Abstract: | Experimental data of magnetic core under repeated magnetization, usually used during the design of high power pulsed equipment, can not accurately reflect its performance under pulsed magnetization. A method of magnetic core test and data processing under pulsed magnetization is given. The loss characteristics of a kind of glassy alloy magnetic core under pulsed magnetization are experimentally studied. The relationship between magnetic core loss and magnetization rates is presented. The saturation time ranges from 67 to 1 410 ns and the magnetization rate ranges from 1 to 40 T/μs. The percentages of hysteresis loss and eddy loss are analyzed. The experimental results show that the relationship between magnetic core loss and magnetization rates accords with the saturation wave model. Moreover, the core loss is directly proportional to the magnetization rate. |
