摘要
对航天器一次电源核心设备电源控制器(PCU)的重要组成部分——顺序开关分流调节器进行了分析研究。结合顺序开关分流调节器的工作原理,通过分析输出母线电压纹波确定了母线电容的选取;建立了顺序开关分流调节器的小信号模型,对系统输出阻抗进行了设计。基于PSIM的仿真和实验结果对所设计的输出阻抗进行了验证。
The sequential switching shunt regulator(S3R),namely,the core parts of the power conditioning unit(PCU)was analyzed.Based on the principle of the sequential switching shunt regulator,the bus capacitor was chosen by analyzing the output bus voltage ripple.The small signal model of the sequential switching shunt regulator was built,and the output impedance was presented.The PSIM simulation and experiment results validate the design in the paper.
