摘要
本文研究串级磁脉冲压缩器模拟分析的数学模型。针对两级串级磁脉冲压缩系统，考虑到采用“小伏秒耐量、短阻断时间”的优化设计技术时各压缩级电路之间的相互影响以及磁开关磁芯内部的瞬态电磁过程，提出了磁开关的不饱和－饱和线性模型与非线性模型，从而相应地得到了磁脉冲压缩器较为简略的线性近似模型和较为精确的非线性的模拟分析数学模型。由线性近似模型可较为便捷地估算电路响应，而从非线性模型出发，通过计算机数值运算，即可从时间和空间两方面模拟磁开关磁芯的饱和和磁化过程，精确地模拟压缩器电路的暂态响应。
he mathematical model is studied for the simulation of series magnetic pulse compres-sor (SMPC) in this paper. With regards to two-stage SMPC, taking into account the tran-sient electromagnetic processin the cores of magnetic switches and the interaction of com-pressor stages when applying the optimization technique of 'smaller volt-second rating ,shorter holdoff time', we present a nonsaturation-saturation linear model and a nonlinearmodel for magnetic switch ,thus obtain a relatively simpler linear approximation model and anonlinear model for the simulation of SMPC, Circuit response can be calculated more conve-niently with the linear approximation model , while with the nonlinear model , by means ofcomputer calculation . the saturation and magnetization process of the magnetic switch corescan be simulated temporally and spatially , thus the circuit response in SMPC can be calculat-ed more precisely.
