摘    要:本文对高功率直线脉冲变压器常用的一种0.08mm薄带DG4型硅钢片绕制的环形磁芯的脉冲磁化特性进行了实验研究。结果表明,在周期为百微抄量级欠阻尼振荡激磁电流作用下,磁芯磁滞回线基本上与工频电流激磁时相同,而周期在微秒量级欠阻尼振荡激磁电流作用下,磁芯在激磁电流第一个脉冲磁化达到饮和后,当激磁电流反向时,磁芯不能随之反向磁化,而是一直处于饱和状态,失去磁性。

关 键 词:DG4型0.08mm薄带  硅钢磁芯  脉冲磁化特性  高功率直线型脉冲变压器

Abstract:The pulsed magnetizing property of the core made of 0.08mm foil DG4 material for the pulsed linear transformer device is studied by the experiments in this paper, which is used usually in the pulsed linear transformer driver. The experimental results indicate that the core hysteresis at the period of the magnetizing current of about several hundred microseconds is the same as that of the core at the frequency of the 50Hz magnetizing current, while the core hysteresis is different from that of the core at the period of the magnetizing current less than several-tens microseconds. When the range of the period of the magnetizing current is several microseconds, the core keeps the magnetizing property at the first pulse of the damp oscillating discharge current, and it always keeps saturated at the rest of the damp oscillating current.
Keywords:high power  pulsed linear transformer device  hysteresis  pulsed magnetizing property
