摘要
从buck变换器的数学模型出发,建立buck变换器的二维滑模控制器,在此基础上对控制器的硬件电路及电路中的主要元器件参数进行设计,并对该电路进行仿真和实验,得出buck变换器的输出电压波形。从波形图可以看出,仿真结果和实验结果基本吻合,表明该电路的正确性和实用性。
The buck converter controller is established based on two-- dimensional sliding--mode from the buck converter＇s mathematical model. The controller＇s hardware circuit and parameters of the main components are designed based on the controller＇s mathematical model, and the simulation and experiment are carried on this circuit, the buck converter＇s output voltage waveform is obtained. The simulation results and experimental results are basically consistent, and the correctness and practicality are verified from the waveform.
