Research status and prospect of spacecraft solar array charge-discharge effect and electrostatic discharge induced protection design

Abstract

For a long time, the spacecraft solar tianchi array system USES 28V main voltage, with the continuous improvement of the requirements for energy system, the future spacecraft solar array power system will develop towards the trend of high power, high voltage. However, the significant increase of working voltage increases the coupling effect between solar array and space charged environment, and the permanent failure of solar array due to space electrostatic discharge (SESD) occurs. It is found that high voltage (HV) components are the main fault source of battery array failure. Therefore, in this paper, through summarizing the space solar cell array in a discharge and the mechanism of secondary discharge and domestic related research institute work, further induces cell array produced during orbiting inducing factors and the main protection methods of electrostatic discharge, put forward to strengthen the solar cell array under the influence of electromagnetic field outside the discharge mode and law of exploration prospects, on how to carry out field induced protection has carried on the preliminary analysis, this paper introduces the principle and structure, plasma environment simulation equipment test method, to study to strengthen the influence law of electromagnetic fields on the sun tianchi array electrostatic discharge laid a foundation.
