【摘要】：针对双LCC谐振补偿电路结构的研究中缺乏考虑系统增益特性,忽略电路整体的输出特性的不足,提出采用基于互感模型的阻抗特性分析法,该方法兼顾谐振系统的输出特性,确定一个与负载和耦合系数无关的固定频率点,在此频率点下发现了谐振电路具有纯阻性和恒流源输出的特性.提出两种实现前级H桥变换器ZVS的参数优化方法,从谐振电路增益角度对比分析了这两种优化参数方法对谐振系统输出特性不同的影响.设计了一台3.3kW的基于双LCC谐振补偿电路的变换器,仿真和实验验证了针对谐振补偿电路特性的分析及优化方法的正确性.
[Abstract]:In the study of double LCC resonant compensation circuit structure, the gain characteristics of the system are not considered, and the output characteristics of the whole circuit are ignored. An impedance characteristic analysis method based on mutual inductance model is proposed, which takes into account the output characteristics of the resonant system. A fixed frequency point independent of load and coupling coefficient is determined. At this frequency point, it is found that the resonant circuit has the characteristics of pure resistance and constant current source output. Two parameters optimization methods are proposed to realize the ZVS of the former H-bridge converter. From the angle of resonant circuit gain, the effects of these two optimization parameters on the output characteristics of resonant system are compared and analyzed. A 3.3 kW converter based on double LCC resonant compensation circuit is designed. The simulation and experiment verify the correctness of the analysis and optimization method for the resonant compensation circuit.
