脉冲压缩电路磁开关动态特性
资料介绍
提出在典型一阶磁脉冲压缩电路的基础上,测取磁芯在实际工作条件下的动态磁滞回线和饱和磁导率等磁参数,再根据所获得的动态参数指导磁开关设计,进行一阶磁压缩实验。实验选取国内外被广泛应用的非晶磁芯和纳米晶磁芯进行测试,根据实测动态磁参数设计磁开关。实测结果表明：用国产非晶磁芯做磁开关可得到上升沿73ns、电压幅值28.3kV、半高宽为503ns的脉冲,用日本产的纳米晶磁芯做磁开关可得到上升沿30ns、电压幅值28.4kV、半高宽为193ns的脉冲。
On the basis of one-order magnetic pulse compression（MPC） circuit,this paper puts forward a method for measuring the dynamic magnetic properies of magnetic cores in actual working conditions,such as hysteresis loop and saturated permeability,to guide the design of magnetic switches in the MPC experiments.Widely used amorphous magnetic cores and nanocrystalline magnetic cores are chosen,and their dynamic magnetic parameters are obtained.The magnetic switch using domestic amorphous magnetic core,outputs pulses of 73 ns risetime,28.3 kV peak voltage,and 503 ns full width at half maximum.The magnetic switch using Japanese nanocrystalline magnetic core outputs pulses of 30 ns risetime,28.4 kV peak voltage,and 193 ns full ...
