摘 要:
提出了应用于小型风力发电系统的Buck电路结构。采用几何参数法（K—G法）设计电感；并基于PWM开关模型．建立了Buck电路的小信号交流模型。在Matlab环境下，分别建立了Buck电路的电路仿真模型和传递函数仿真模型，并利用该模型构建了以蓄电池和电阻为负载的风电系统模型。对蓄电池恒压和浮充充电的仿真结果表明，Buck电路能满足风电系统功率控制的要求。[著者文摘]

Abstract:
The paper presents a Buck circuit structure for small wind power system. The inductor is designed by geometry parameter method （K-G method）, and a small-signal alternate model is built based on model of the PWM switch. The circuit simulation model and transfer function model of Buck converter are developed under MATLAB environment, and then by these models, the model of the small wind power system is built by using secondary battery and resistance as load. The simulation results of constant voltage charging and floating charging show that the Buck converter can satisfy all requirements of power control in wind power system.[著者文摘]
