摘要
分析了反激式变换器的工作原理,并根据该变换电路的工作方式,利用状态空间平均法建立了该拓扑的系统数学模型,采用滑模变结构控制方法来控制系统状态之间的切换,通过MATLAB/Simulink仿真和实验验证该变换器拓扑的实用性和滑模控制策略的有效性。
The working principle of the flyback converter is analyzed,and the mathematical model of the topology is established by means of the state space averaging method.The sliding mode control method is adopted to control the system state between the states of the flyback converter.Finally,the feasibility of the converter topology and the effectiveness of the sliding mode control strategy are verified by MATLAB/Simulink simulation and experiment.
