针对半桥LLC谐振变换器工作原理分析复杂、参数设计直观性较差等问题，根据谐振电流、励磁电流的变化关系，简化了半桥LLC谐振变换器工作原理的分析。由变换器的等效电路模型分析了其电压增益、阻抗特性，并通过相应的电压增益曲线、阻抗特性曲线直观地分析了各参数间相互关系，给出了参数的优化设计步骤。最后设计了180W/24V驱动电源，仿真及实验结果均达到预期效果。

To solve those problems such as difficulty in analyzing working principle of half-bridge LLC resonant converter,unintuitivity of parameter design, analysis of the working principle of the resonant converter was simplified based on the relationship between resonance and excitation current. Voltage gain and impedance characteristics was analyzed according to equivalent model, and the mutual relationship between the parameters was analyzed from curves of voltage gain and impedance characteristics. Parameter optimization design procedure was given. Finally a 180W/24V drive power was designed and desired simulation and experimental results were obtained.
