摘要
S4MPR电源调节技术在航天器出阴影区最大效率地利用了太阳电池阵列可输出的最大功率。将该电源调节非线性模型采用输入电流滞回法建立其线性模型,并针对太阳电池阵列PV及IV输出特性采用稳态小信号法优化了MPPE采样步偿。实验与仿真验证了S4MPR供电系统的最大功率充电特性与良好的负载母线调整能力。
S4MPR power conditioning technology in the spacecraft out of the shadow of the earth makes effectively use of the maximum power of solar array. Nonlinear model of the power regulator establishes its linear model using input current hysteretic method, and finds the optimization parameter of the step of MPPE using the Ⅰ-Ⅴ model of PV with small signal method. The fine transient and steady-state response of S4MPR power supply system were verified by simulation analysis and experiment.
