航天器太阳电池阵驱动装置的新进展

通常长寿命三轴稳定卫星都采用帆板式太阳电池阵进行能源供应，并使用太阳电池阵驱动装置使电池阵对日定向。国际上从20世纪60年代开始，不断开发研制太阳电池阵驱动装置,以满足在大功率、小型化、适应恶劣环境等方面的特殊需求，经过几代的发展，取得了长足的进步。根据国内收集的相关信息和资料，通过介绍国际该领域的发展及对应需求的典型产品，尝试分析该领域中相应的应用、研究的重点及发展的方向。

New Development for Spacecraft Solar Array Drive Assembly

Solar arrays are always used by long-lived triaxial stabilized satellites for energy supply, and solar array drive assemblies have to be used to align the solar array for accurate tracking of the sun. Since 1960s, the international development of the new solar array drive mechanism and electronics to meet its special needs, such as high power, miniaturization and harsh environment adaptability, as well as other needs, has gone through 3 to 4 generations of development, with its great progress. Based on the relevant information and data collected, the paper tries to analyze the corresponding application, research focus and development direction in this field, by introducing the international typical product with their corresponding demand in this area.
