This paper introduces the main circuit structure and working principle of LLC resonant converter. Through the analysis of steady state model of LLC resonant converter, based on FHA, equivalent circuit of resonant cavity and DC gain expressions are obtained. Based on the steady-state model, the design method of LLC resonant capacitance, inductance and excitation inductance are given. The accuracy of the steady-state model and the design method of parameters are proved by saber simulation.
