摘　　要：高效稳定的母线电压技术是保证导航卫星信号连续的重要前提。针对导航卫星大功率设备多和导航服务不间断的特点,详细分析并设计了一套高精度全调节多母线电压调节系统,解决了全轨道周期、全温度范围多母线电压调节的稳定性以及大功率负载切换时母线的瞬时响应问题。经北斗导航组网卫星地面和在轨应用验证,该调节系统稳定性好且母线电压精度较高。Efficient and stable bus voltage technology is an important prerequisite to ensure the continuity of navigation satellite signals.According to the characteristics of navigation satellites with multiple high-power equipment and uninterrupted navigation service,a set of high-precision fully-regulated multi-bus voltage regulation system is analysed and designed in detail,which solves the stability and large-scale regulation of multi-bus regulation in full orbit period and temperature range,and the instantaneous response of bus during high-power load switching.The ground and on-orbit applications of BeiDou navigation satellites show that the system has good stability and high bus voltage accuracy.
