摘　　要：为了进一步提高空间用充电调节器的可靠性和功率密度,建立了基于Buck变换器的新一代空间用电源系统充电调节控制系统,应用状态空间平均法建立了Buck变换器动态小信号模型,根据输入电流与占空比关系,构建基于跨导控制的双闭环控制系统,对系统稳定性进行研究,最后搭建了实验样机,实验证明系统具有良好的瞬态响应速度和抑制输入扰动的优点,证明了模型的正确性和控制策略的有效性。In order to further improve the reliability and power density of the space charging regulator,a control system for a new generation of space power system based on buck converter was established. A dynamic small-signal model of Buck converter was established by using the state space averaging method. Based on the relationship between input current and duty cycle, a double closed-loop control system based on PWM conductance control was established, and the stability of the system was studied. Finally, the experimental prototype was established and the experiment was proved. The system has the advantages of good transient response speed and suppression input disturbance, and proves the correctness of the model and the effectiveness of the control strategy.
