摘要
通过建立和分析同步降压型(Buck)开关电源小信号平均模型,阐述了连续电流模式下同步降压开关电源纹波电压的产生原因,并给出其抑制方法。仿真分析及实际应用证明,该法能有效减小纹波电压,适合于工程应用。
Based on the creation and analysis of the small-signal average model about synchronous Buck switching converter in continuous current-mode,the reasons for ripple voltage are explained and the actual method or inhibition ripple voltage is given.When using this method, ripple voltage can be reduced, and this method is suitable for engineering applications after simulation and actual certification.
