S4R最小系统仿真与验证

Simulation and test of minimum system of S4R

S4R功率控制技术代表了目前空间电源控制技术的前沿水平,对S4R(Sequential Switching Shunt Series Regulator)功率控制技术最小系统的模块化工作特性和工作模式进行了分析验证。应用Saber仿真工具对S4R最小系统进行了系统仿真,验证了S4R单元模块供电/充电/分流的三态工作模式和模块间的顺序工作关系。

S4R（The Sequential Switching Shunt Series Regulator） power control technology is a representative of the cutting edge level of the current space power control technology.The module work specialty and operation mode of S4R power control system composed of S4R unit module and BDR（Battery Discharge Regulator） module were analyzed theoretically.By using Saber simulation tools,the S4R minimum system constructed of these modules were analyzed to prove the supply/charge/shunt working state of S4R unit module and sequential operation mode between modules.
