摘　　要：在稳态等离子体发动机工作过程中存在频率范围为1~100 k Hz的低频振荡,将对发动机性能产生不良影响。针对霍尔推力器中的电感滤波器,通过实验研究给出电感补偿对回路振荡的影响规律,研究出振荡、相位差和频率三者间的关系,通过半离散化的一维流体模型进行仿真,仿真结果与实验相吻合。1~100 k Hz low frequency oscillation exists during the operation of Stationary Plasma Thruster（SPT）, which will lead to adverse impact on the performance of SPT. In view of inductance power filter, according to experimental study, this paper concludes the rules that how inductance compensation influences the loop oscillation and studies the relations among oscillation, phase difference and frequency. It also completes simulation experiment through semi-discrete one-dimensional fluid model, with a coincident result.
