摘　　要：提出了一种新的开关分流调节系统的设计方法,将太阳电池阵划分为大阵和小阵,采用数模混合控制的方法对大小阵进行分别控制,让大阵工作在常供电或常分流态,仅有小阵处于开关调节状态,有效解决了寄生电容对开关分流调节系统的影响。采用基于Saber和MATLAB/Simulink软件的仿真环境,对新的开关分流调节系统进行了仿真验证。结果表明,文章提出的开关分流调节系统设计方法合理可行,系统稳态和瞬态工作特性能够满足航天器在轨运行的需求。A new switch shunt regulator power system for spacecraft is presented. The solar array is divided into big sections and small sections, and the regulator is controlled by mixed analog- digital control method to make only small sections work in switching state. This design effectively reduces the influence of parasitic capacitance of solar array on switch shunt regulator system. Based on Saber and MATLAB/Simulink simulation environment, the principle of new switch shunt regulator system is verified. The simulation results show that the design is reasonable and practicable, and both the system steady state and transient operating characteristics can meet the demand of the spacecraft.
