针对松耦合变压器耦合系数较低和漏感的问题,对非接触电能传输装置的结构特性和补偿方式进行深入研究。借助Maxwell软件对松耦合变压器的磁场进行仿真分析,求解磁场的分布情况和不同气隙下对应的自感互感参数,并结合等效电路和松耦合系统的互感模型,阐明了四种补偿方式电容参数的计算过程。最后,通过理论计算和Multism仿真分析,研究不同补偿方式和多种因素对系统传输功率的影响。不同因素对传输功率影响的分析结果,可以为实际工程设计提供参考,具有重要的意义。

In view of the problems about the low coupling coefficient and the leakage inductance of the loose coupling transformer,the structural characteristics and compensation methods of non-contact power transmission equipment are deeply studied.With the Maxwell software,the magnetic field of the loose coupling transformer is simulated and analyzed,and the distribution of magnetic field and the parameter of self-inductance and mutual inductance with the change of air gap are solved.Combined with the equivalent circuit and the mutual inductance model of the loose coupling transformer,the calculation process of the compensation parameters of the four kinds of compensation modes is illustrated.Finally,through theoretical calculation and Multism simulation analysis,the impact of different compensation methods and different factors on the transmission power of the system is studied.The analysis results of the influence of different factors on the transmission performance can provide important reference for the actual engineering design,which is of great significance.
