摘要
LLC变换器的建模是设计其闭环控制系统的关键,对于保持电路输出电压的稳定和良好的动态响应特性具有非常重要的影响。选取了小信号模型作为建模方法,获取了电路的等效电路模型及传递函数,并通过在Matlab软件中搭建系统的仿真电路进行仿真,通过仿真曲线验证了模型设计的正确性及闭环的作用。
The modeling of LLC converter is the key to design its closed-loop control system,and it is very important to maintain the stability of the output voltage and the good dynamic response characteristics of the circuit.The small-signal model is selected as the modeling method,the equivalent circuit model and the transfer function of the circuit are obtained,and the simulation circuit of the system is built in the Matlab software.The correctness of the model design and the function of the closed loop are verified by the simulation curves.
