摘要
Buck变换器具有电路简单和输出电压调节控制性能好的特点,文中主要介绍Buck变换器电路结构和降压原理,定量分析CCM下Buck变换器的小信号分析,及在SIMULINK下的三种建模仿真。实践证明,在电路设计中,利用仿真模型,将会更有效地加快可调功率变换器的设计。
Buck converter has a simple circuit and a good performance of regulating output voltage. In this paper, the circuit structure and step-down theory of Buck converter are introduced. Small-signal analysis of Buck converter is quantitatively analyzed under the CCM and three kinds of modelling simulation under the SIMULINK are also analyzed. Practice proves that the design of adjustable power converter will be effectively speeded up by using simulation model.
