摘要
分析了Buck-Boost(反极性开关调节器)变换器的原理,指出了电压型、电流型、V2型等多种控制方法的优点和不足。为了达到更好的控制效果,在此基础上提出了多环控制方法,并对其进行了分析研究。介绍了其工作原理,建立了器件模型,用Matlab的Power System Blockset工具箱对该模型进行了仿真,将仿真结果与传统的控制方法进行比较,结果表明多环控制的动态特性好于传统的控制方法,从而验证了分析的正确性。
The paper analyzes some control methods of Buck-Boost Converter,include current mode control technique 、voltage mode control technique and V2 mode control technique.On the basis of upward introduced a mode of Multi-Loop Control for Buck-Boost Converter and analyzed the mode,instructed the principle of this mode and the component model of multi-loop control Buck-Boost Converter was derived.Simulated by Matlab Power System Blockset toolbox.The analysis and simulation results were compared with traditional con...
