摘要: 将二端口电路理论引用到非接触电能传输(CPT)系统中,通过二端口理论对LCL复合补偿型CPT系统进行建模分析,发现了其输入与输出电压间的倍数关系。同时,对耦合机构进行了重新建模,使其分析变得简单明了。在此基础上,给出了整个系统的参数配置方式,并分析了其输出电压和功率、效率特性。为证明此参数配置方式优越性,推导了SS型CPT系统的输出功率公式,并进行对比。结果发现所述方式能够输出更大的电压和功率,仿真和实验同样证明了所述结论。Abstract: The two-port circuit theory is introduced to a contactless power transfer（CPT）system,by means of which an LCL type CPT system is modeled and analyzed.After that,the relationship between the input and output voltage is found.At the same time,the new model of the coupling mechanism is given,which makes the analysis very simple.Based on this,a new parameter configuration method of the whole system is given,and the output voltage,power and efficiency characteristics are analyzed.In order to prove the superiority of this method,the output power formula of an SS type CPT system is deduced and compared.The results show that the proposed method has a much higher output voltage and power as proved by simulation and experimental results.
