摘　　要：介绍了半桥LLC谐振变换器的工作原理,研究了半桥LLC谐振变换器的稳态建模,利用MATLAB软件绘出其直流增益曲线,在此基础上分析了变换器主要参数对其工作性能的影响。样机实验验证了理论分析的正确性。The principle of half bridge LLC resonant converter is introduced. The paper emphasizes on the modeling of the steady state of half bridge LLC resonant converter. The soft MATLAB is used to draw the curve of the DC gain, on the basis of this the influence of the main parameters to the converter is analyzed. At last, a prototype is designed to validate the correctness of theory analysis.
