| 摘 要： | 建立了快脉冲磁芯损耗特性测试平台，对比研究了50 m的DG6硅钢和25 m的2605TCA非晶两种材料磁芯损耗特性；采用一种新的特征参量(磁芯单位面积上激磁电压陡度)来规范磁芯的激磁电压条件，使得实验结果与快放电直线型变压器驱动源实际工作条件下磁芯性能具有可比性；通过测量初级漏电流及次级开路电压，获得了相同激磁条件下两种磁芯等效损耗电阻的大小，50 m 的DG6硅钢磁芯损耗约为25 m的2605TCA非晶磁芯损耗的4倍；计算了两种材料磁芯总损耗中涡流损耗所占的比例，50 m的DG6硅钢磁芯涡流损耗占总损耗的75%，25 m的2605TCA非晶磁芯涡流损耗占总损耗的28%。

| Abstract: | The test platform has been developed to generate exciting pulsed voltages with the rise time less than 30 ns. The loss characteristics of cores of 25 μm 2605TCA Metglas and 50 μm DG6 electrical steel were then studied. A characteristic parameter, the gradient of the voltage pulse applied per unit core area, is proposed to describe the exciting condition applied on magnetic cores. The loss of the DG6 core is about 4 times that of the 2605TCA core. Most loss of the DG6 core, about 75%, is due to eddy current. For the 2605TCA core, the percentage is about 28%. |
