本文的目的是通过Saber-Simulink联合仿真来验证作者建立的峰值功率跟踪(PPT)卫星电源控制器的有效性以及这种联合仿真方法的合理性。首先在MATLAB/Simulink中建立卫星电源控制器模型,包括PPT控制器模块,工作模式转换模块以及恒流-恒压(CC-CV)充电控制器模块。结合Simulink和Saber两者的优势,详细介绍了两软件接口定义方法并对基于PPT的卫星电源系统进行联合仿真。仿真结果表明卫星电源控制器工作模式切换正常,Saber-Simulink联合仿真是一种可靠的系统仿真方法,适合用于卫星电源控制器的仿真。

The purpose of this paper is using Saber-Simulink co-simulation to verify effectiveness of the peak power tracking（PPT）satellite power controller and rationality of this co-simulation method.First of all,a model of the satellite power supply controller is created in MATLAB /Simulink,including a PPT controller module,a mode conversion module as well as a constant current-constant voltage（CC-CV）charge controller module.Then combining the advantages of both Simulink and Saber,the definition method of their interfaces is introduced particularly,and then co-simulation of satellite power system was completed.The results show that the satellite power controller works normally,so the Saber-Simulink co-simulation is a reliable method of system simulation,and it is suitable for the simulation of satellite power controller.
