In this paper, the electrostatic discharge of solar arrays in spacecraft energy systems is taken as the research object. The influence and internal mechanism of external electromagnetic radiation on electrostatic discharge is studied. Meanwhile, the charging and discharging test platform of spacecraft solar arrays under a strong field is first established. Then, the influence of irradiation field strength, electron beam energy and beam density on electrostatic discharge of solar arrays is analyzed and summarized. The results show that during the irradiation process of solar arrays using a high-energy electron beam under vacuum conditions, the higher the electron beam energy and the beam current density, the higher the discharge frequency of the solar array. When the intensity of the external electromagnetic radiation field increases, the discharge frequency also increases. Under the action of external radiation field with the same peak field strength, the larger the gap, the smaller the discharge frequency. With the increase in the field strength, the potential difference of each part of the solar array becomes smaller, and the peak of the discharge current decreases. The research results can provide technical reference for electrostatic protection of spacecraft solar arrays.

ESD EMP作用下太阳能电池阵的感应静电放电研究

本文以航天器能源系统中太阳能电池板的静电放电为研究对象。研究了外部电磁辐射对静电放电的影响及其内在机理。同时，首次建立了强场下航天器太阳能电池组充放电试验平台。然后，分析总结了辐照场强、电子束能量和束流密度对太阳能电池板静电放电的影响。结果表明，在真空条件下使用高能电子束照射太阳能电池板过程中，电子束能量和束流密度越高，太阳能电池板的放电频率越高。当外部电磁辐射场的强度增加时，放电频率也增加。在相同峰值场强的外辐射场作用下，间隙越大，放电频率越小。随着场强的增大，太阳能电池阵各部分的电位差变小，放电电流的峰值减小。研究成果可为航天器太阳能电池阵列的静电防护提供技术参考。
