摘　　要：以原副边均采用串联补偿方法进行研究,分析了非接触感应电能传输系统的高阶数学模型,探究了频率分叉实质,利用Matlab进行曲面仿真,了解系统的频率分叉现象,从而得出较为合理的补偿方案。分析了发生频率分叉时,如何选择优化的工作频率,采用移相控制的方式使系统得到稳定的输出。The higher-order mathematical model of the loosely-coupled inductive power trans- fer system is analyzed, using series compensation in primary and secondary sides. The essence of frequency bifurcation is investigated. Using the Matlab simulated curved surface, the frequency bifurcation phenomena can be observed. Therefore, the proper compensation scheme is presented. Finally, how to choose the optimal working frequency when the frequency bifurcation happens is analyzed, and the stable voltage output is obtained by using the phase shift full bridge control.
