The invention discloses a space low-rail high-voltage power supply system supporting on-rail maintenance, and belongs to the technical field of space power supplies. The system comprises two independent power channels, the two power channels have the same function composition, and energy is provided for a spacecraft load through energy grid connection; each power channel takes the solar cell wing as a starting point and the bus filter as an end point to form an independent 100V power supply bus; each power channel comprises a solar cell wing, a driving mechanism, a shunt regulator, a bus filter, a comprehensive driving controller, a charging and discharging regulator, a lithium ion storage battery pack and a power manager; and the solar cell wing, the shunt regulator, the bus filter, the comprehensive driving controller, the charging and discharging regulator, the lithium ion storage battery pack and the power manager are minimum replaceable units (ORU). Under the condition that related products of the power supply system break down, astronauts carry out on-orbit maintenance operation, and the service life of the power supply system is prolonged.
一种支持在轨维修的空间低轨高压电源系统,属于空间电源技术领域。本发明包括两条独立的功率通道,两条功率通道功能组成相同,通过能源并网为航天器负载提供能量;每条功率通道以太阳电池翼为起点,母线滤波器为终点,形成一条独立的100V供电母线;每条功率通道包括太阳电池翼、驱动机构、分流调节器、母线滤波器、综合驱动控制器、充放电调节器、锂离子蓄电池组和电源管理器;太阳电池翼、分流调节器、母线滤波器、综合驱动控制器、充放电调节器、锂离子蓄电池组、电源管理器为最小可更换单元ORU。本发明在电源系统相关产品出现故障情况下,通过航天员在轨进行维修操作,延长电源系统的使用寿命。
