| 摘 要： | 为揭示非接触电能传输(Contactless Power Transfer,CPT)系统频率分裂现象的成因,用Bode图考察系统传递函数3个子环节的贡献,指出对称串联型CPT系统的频率分裂现象是由两个二阶振荡环节的谐振引起的.数值仿真和实验结果表明,尽管两个二阶振荡环节的谐振频率是对称CPT系统奇偶分裂频率的定性估计,Bode频域分析方法仍可为理解CPT系统频率分裂现象提供一个新思路.

| Abstract: | To reveal the origin of frequency splitting phenomena of Contactless Power Transfer (CPT) systems, Bode diagrams are used to evaluate the contributions of three factors of the system transfer function, and it is found that frequency splitting phenomena of symmetrical series tuned CPT systems result from the resonance of two second order oscillating factors. Numerical simulations and experimental results indicate that Bode frequency analysis is still a new approach to understand the frequency splitting phenomena of CPT systems, although the resonant frequencies of two second order oscillating factors are qualitative estimations of the even and odd splitting frequencies of symmetrical CPT systems. |
