S4R功率调节技术在航天器上的仿真研究与实现

Simulation Study and Implementation of the Sequential Switching Shunt Series Regulator(S4R) Power Regulator to the Spacecrafts

对于大功率母线的航天器,传统的母线功率调节技术因为诸多缺点已经不能适应母线功率不断增大的要求。S4R作为一种新型的卫星母线调节技术能够很好的控制母线电压,同时具有优良的电池充、放电特性和很高的效率。在对国、内外S4R技术研究的基础上,从S4R的工作原理出发,给出了S4R功率调节技术的实现策略。在此基础上进行了实际电路的仿真分析,最后给出了部分实际的工作波形.并展望了其应用前景。

As for the spacecrafts platform with the high power busses, the tradition bus power regulator cannot accommodate the development of the spacecrafts platform power need. The sequential switching shunt series regulator （S4R） acts as a new bus power regulation technology can fully regulate the bus voltage, and then at the same time it has excellent characteristics of charger and discharger and high efficiency. Based on the study of the S4R home and abroad, this paper is to analyze the S4R operating principle and its implement way, and the simulation analysis based on the practical circuit is also given. Finally, this paper gives not only the practical waveforms, but also its application prospects.
