Modeling of Interleaved Magnetic Integrated Bidirectional DC/DC Converter in Boost Mode
摘要
Abstract
To improve the operation reliability of interleaved magnetic integrated converter and better guide the design of controller,in this paper,the operation of the converter in boost mode with composite power is analyzed,and the cor-responding relationship is obtained among coupling degree,steady inductor current ripple,transient current response speed in the duty cycle. Based on perturbation method and state space average method,a dynamic small signal model-ing is conducted,and the open loop transfer function is obtained,which describes the transfer of control variables to state variables. The use of interleaved magnetic integrated technology can effectively reduce the inductor current ripple , improve the efficiency of the converter and the dynamic response speed of the system. Then the amplitude-frequency curve and phase-frequency curve are plotted by Matlab simulation,based on which the feedback loop compensation is designed to improve the system stability and dynamic response speed. The results of the analysis are verified through simulation and experiment.关键词
