摘要
本文基于电压控制型Buck电路提出了一种双极点双零点补偿网络控制器,用一对零点来抵消输出滤波器双重极点的谐振增益,通过建立Buck变换器的小信号等效电路模型,应用MATLAB对补偿器和整个电路进行了仿真分析,验证了理论分析与设计的正确性,设计的变换器在保持足够的稳定裕度下可获得较好的稳态和动态性能。
A PI compensator controller with two poles and two zeros was proposed to decrease the system resonation for voltage mode Buck converter. Using an averaging model and MATLAB simulation, the small signal model and the compensator contraller were analyzed and discussed. The good static and dynamic performance was verified by MATLAB simulation.
