摘　　要：针对半桥LLC谐振变换器谐振参数设计较困难的问题,采用基波分析法(FHA,First Harmonic Approximation)建立等效模型,然后分析LLC变换器实现零电压开通的约束条件,得到LLC谐振参数优化设计的方法。最后通过Saber搭建仿真平台,验证该参数设计的正确性。In order to solve the problem that the design of the resonant parameters of the half bridge LLC resonant converter is difficult,this paper uses the First Harmonic Approximation method to establish its equivalent model,and then analyzes the constraint conditions of the LLC converter to realize the zero voltage switching,and obtains the optimization design method of the LLC resonance parameters.Finally,Saber is used to build a simulation platform to verify the correctness of the proposed theoretical parameter design.
