| Abstract: | This paper presents a modeling method commonly used in switching converters-the average of energy conservation.Based on the average conservation of energy principle,a continuous mode DC buck converter and the small-signal model are established,and given the open-loop transfer function.The proposed model is validated by detailed simulation and is shown to accurately predict small-signal frequency domain characteristics. |
