The effect of discharge loop inductance compensation on hall thruster

摘要

1-100KHz low frequency oscillation exists during the operation of Stationary PlasmaThruster(SPT),which will lead to adverse impact on the performance of SPT. In view of inductancepower filter, according to experimental study, this paper concludes the rules that how inductancecompensation influences the loop oscillation and studies relations among oscillation, phasedifference and frequency. It also completes simulation experiment through semi-discreteone-dimensional fluid model, with a coincident result. The result shows that, with the increase ofinductance, electric current oscillation and fall of frequency, the voltage oscillation, electric currentand voltage phase difference increase.
