摘　　要：考虑到卫星供电的安全性和可靠性,传统的顺序开关分流调节(Sequential Switch Shunt Regualator,S3R)电源系统在光照期大部分时间处于分流或分流调节状态,但部分科学载荷要求电源系统不能处于分流调节状态,针对这种特殊需求提出一种可以规避分流调节状态的S3R电源系统。在评估电源系统能量平衡的前提下,采用软件、硬件相结合的方法提前将相应的分流电路设置为强制分流,使得太阳能电池阵能够供给到母线的功率受到控制,从而规避分流调节状态的出现。Considering the safety and reliability of satellite power supply,the traditional Sequential Switch Shunt Regualator(S3R)power supply system is in a state of shunt or shunt regulation most of the time during the light period,but some scientific loads require that the power system cannot be in a shunt state.Regulating state,a S3R power supply system that can avoid the shunt regulating state is proposed for this special requirement.On the premise of evaluating the energy balance of the power supply system,a combination of software and hardware is used to set the corresponding shunt circuit to forced shunt in advance,so that the power supplied by the solar cell array to the bus is controlled,thereby avoiding the occurrence of the shunt regulation state.
