摘要：

文章对电流连续工作模式（CCM）下LCC谐振变换器的工作模态进行了分析，在此基础上采用基波近似法对LCC谐振拓扑进行了简化，推导出LCC谐振变换器的基波纯阻性和基波容性等效电路，建立了与开关频率、负载及变换器增益有关的数学模型.结合模型，提出了宽范围输入输出电压LCC谐振拓扑的设计方法，基于此方法结合一套电源设计指标设计了一组谐振参数.通过仿真验证了所设计的LCC谐振变换器在宽范围输入输出电压条件下可实现全负载范围的软开关，满足设计指标，证明了模型和设计方法具有较高精准度和良好应用价值.
Abstract:

The paper makes a full analysis for the working mode of the LCC resonant converter in the continuous current mode (CCM). On this basis, further researches need to be completed which include analyzing the LCC resonant topology using Fundamental Wave Approximation, deducing its fundamental wave equivalent circuit of pure resistance and capacitive, and building its mathematical model related with the switch frequency, load and convert gain. On the grounds of the model, a design method of LCC resonant converter operating under a wide range input and output voltage is proposed, and a list of resonant parameters is designed for a set of power supplies based on the method. Then, Simulation results demonstrate that the designed LCC resonant converter can achieve the full-load range soft-switching under a wide range of input and output voltage and meet the design specifications. Besides, it proves that the model and the design method have high accuracy and good application value.
