摘要
介绍了LLC的拓扑结构,对LLC建立基波等效模型,分析了它的工作原理,并对LLC三种工作区域下的工作过程做了详细分析,然后设计了一个输入DC350~640V,输出DC440V,功率为3KW的直流电源,最后在PLECS仿真软件上建立仿真模型,搭建电压闭环,验证了设计的可行性。
This paper introduces the topology of LLC,establishes the fundamental equivalent model of LLC,analyzes its working principle,and makes a detailed analysis of the working process of LLC in three working areas,then designs a DC power supply with input of DC350~640V,output of DC440v and power of 3KW,and finally establishes a simulation model on PLECS simulation software to build a voltage closed loop to verify the design.
