阐述了双buck电路的直流分配电系统的整体结构和工作状态，通过改进主电路的驱动电路，实现快速且高可靠

率的保护，并且完成了MATLAB/Simulink 中的仿真。其结果表明系统软启动工作时输出电压能够稳定上升，超调量大大降

低。输入端电流不出现较大的尖峰，具有较好的稳态响应。

The overall structure and working state of the DC distribution system with double buck circuit are described. By improving the driving circuit of the main circuit, the fast and high reliability protection is realized, and the simulation in Matlab / Simulink

is completed. The results show that the output voltage can rise steadily and the overshoot can be greatly reduced when the system

works in soft start. The input current does not have a large peak and has a good steady-state response.
