LHT-100霍尔推力器滤波设计与放电震荡关系研究

The relation research between filter design and discharge oscillations of LHT-100 Hall thruster

为了对LHT-100霍尔推力器放电震荡进行抑制,研制了与推力器相匹配的放电震荡抑制装置。结合国内外霍尔推力器放电震荡研制背景,通过仿真分析和集成试验两种手段,对LHT-100霍尔推力器放电震荡情况进行了研究。根据试验结果表明滤波参与下放电回路震荡得到了有效抑制,为电推进系统稳定工作提供了可靠保障。

In order to reduce the level of discharge voltage oscillations of LHT-100, a filter equipment which is matching with the thruster was proposed. Combined with the research back ground at home and abroad, the LHT-100 Hall thruster discharge oscillations were researched through simulation and integration test. The final test results proved that the discharge oscillations is effectively reduced with filter, which ensure the stability of the electrical thruster.
