将感应加速腔的磁芯回路视为一段单匝的非线性电感线圈,利用PSpice的一些通用元器件组成的子电路对含有磁芯的非线性线圈进行模拟,使其具有饱和、磁滞及频率损耗等非线性特征.通过一些直观的参数设置,可使线圈模型适用于不同的频率范围.介绍了利用线圈模型对直线感应加速器加速组元系统的模拟,得到了与实验相符合的结果.

The cavity around magnetic cores in linear induction cell act as a non-linear winding when the pulses come. This paper explains how to create PSpice model by its normal parts to simulate a non-linear winding with magnetic core, with a flux switch, the model take into account factors such as saturation, hysteresis and the power losses caused by frequency. By change some pellucid parameters, this model can work in different frequency. This paper also gives some practive examples.
