摘　　要：研究电感储能的新型脉冲电源提高效能问题,采用脉冲电容储能型电源,制造复杂。采用开关控制,限制了发展,同时由于给出了脉冲电源的等效电路并导出电路对应的变系数微分方程,方程的解析求解较为复杂。为解决上述问题,建立了电感储能型等效电路的模型,进行仿真,结果明确了电路各元件参数对输出脉冲特性的影响,验证了计算结果的可靠性。研究电感储能型脉冲电源电路参数的取值对输出脉冲电压的特性有着较明显的控制效果,通过适当选择各元件参数的取值,可以获得较小脉冲电压脉宽的同时又有较高的电压幅度。仿真结果为新型脉冲电源系统设计过程中参数的选择提供了可靠的依据。A novel Inductive Energy Storage pulse source has been analyzed, the equivalent circuit was set up, and the differential equation with variable coefficients of the equivalent circuit was derived. For the process of solving the equation is complicated normally, the model of the equivalent circuit was set up. Then the dynamic characteristics of the equivalent circuit were studied. This method was verified by comparing the simulation results of the circuit with the results from Pspice. The research result shows that parameters of the circuit have the control effect on the pulse voltage obviously. And the effect of the circuit parameters on the feature of output pulse has been summarized. From the results of studies, the output pulse with high - voltage and narrow width were obtained.
