在分析霍尔推力器点火启动过程中电源侧脉冲电流形成机理的基础上，通过解析分析和变参数试验的方法研究了外回路参数与电源侧脉冲电流峰值之间的规律。研究结果表明，随着外回路电容和电感的增大，电源脉冲点火电流峰值减小，根据理论推导得到的霍尔推力器点火启动过程电源脉冲电流峰值函数，分析了外回路电感、电容参数对点火脉冲电流的影响，给出了给定电感值下电感线圈匝数、磁环导磁截面积、磁芯材料 BH 曲线的要求，为霍尔推力器放电外回路的参数设计提供理论参考。%Based on the analysis of the formation mechanism of the pulse current in the power supply side during the start-up transient,the relationship between the outer circuit parameters and the pulse current peek in the power supply side was studied by the analysis and experiments under varying parameters.Results show that the pulse current on the power supply side decreases with the increase of capacitance and inductance.Based on the deduced function of peak pulse current on the power supply side,the effects of capacitance and inductance on the power supply pulse current during a Hall thruster start-up transient was studied.The requirement of the turn,magnetic core sectional area,and the BH curve of selected inductor was discussed.This research can provide reference for the outer circuit parameter design in Hall thrusters.
