摘要
首先介绍了LLC谐振变换器的优越性、电路拓扑结构及其工作模式。在此基础上提出利用基波分析法对其进行建模,使用Matlab画出其直流增益曲线作为变换器参数设计的依据。最后将变换器电路在Saber仿真环境下进行闭环仿真,验证了建模方法的正确性以及实际生产中的可行性。
This article introduces the superiority of the LLC resonant converter,circuit topology structure and its working mode firstly. On the basis of the introduce,the model of the converter has been built on the theory of First Harmonic Approximation. Then drawing the dc gain curve which is the basis of parameter design of converter by using Matlab. Finally converter circuit is close loop simulated in Saber to demonstrate the validity of the modeling method and the feasibility in actual production.
