Research on Multiphase Buck Converters Modeling Based on Improved Switch Cycle Average Method
摘要
Abstract
Based on the improved switch cycle average method,this paper proposed a modeling method of multiphase Buck DC converter.Under the inductor current continuous mode (CCM),the method includes the stray parameters of the circuit and the inconsistency of circuit components.The small signal analysis of multiphase Buck DC converter was researched based on the established model.A MATLAB/Simulink simulation model was carried on.The simulation results show that the static and dynamic response of the model results and the circuit simulation results is the same,verifying the effectiveness of the modeling method.关键词
