| 摘 要： | 提出了采用渐开线硅钢叠片的变压器磁芯与螺旋线的一体化的长脉冲产生结构;计算了螺旋线引入磁芯后,电磁波延迟传输的慢波系数和波阻抗参数,以及脉冲形成的输出参数,并开展了数值模拟进行验证。研究结果表明:引入磁芯后,螺旋线上慢波传输时,内外筒电流沿磁芯基底而非磁芯表面;磁芯的径向厚度相对磁芯径向尺寸越小,磁芯对脉冲形成的影响越小。

| Abstract: | A compact structure with transformer core and spiral line was discussed in this paper. The core consisted of involute silicon steel sheets. The characteristic parameters, such as slow wave coefficient and wave transmission impedance of spiral line with core, were calculated. The design of the output parameters of the spiral pulse forming line (PFL) with core was given, and the corresponding numerical simulation was carried out. The results showed that in course of slow wave transmission on spiral line with core, inner and outer cylinder currents flowed along the core base. The smaller the radical thickness of core in comparison with radical size is, the less the influence of core on pulse formation is. |
