存在一种通过使用双向感应电能传输（IPT）对电动车辆的电池进行充电的方法。应用IPT的系统方便、安全、可维护。在之前的研究中，已经提出了双向 IPT 系统的各种控制方案。然而，这些控制方案并不实用，因为用该控制方案控制的谐振电路在效率上没有优化，或者控制方案非常复杂。此外，这些控制方案的通用性较差，因为没有从效率的角度表达谐振电路的适当设计方法。因此，本文提出了谐振电路获得高效率的设计方法，以及考虑IPT系统特性的谐振电路最大效率控制方案。所提出的控制方案通过控制3个控制参数来轻松获得最大效率：谐振电路中的初级侧和次级侧电压的幅度，以及谐振电路的初级侧和次级侧电压之间的相位。此外，这些控制方案和设计方法都是从简单的理论方程推导出来的。最终，实验揭示了所提出的设计方法和控制方案的有效性。
There is a method for charging a battery of electric vehicles by using bi-directional inductive power transfer (IPT). A system applied with IPT is convenient, safe and maintainable. In previous studies, various control schemes for a bi-directional IPT system have been proposed. However, these control schemes are not practical because the resonant circuit controlled with the control scheme is not optimized in efficiency, or the control scheme is highly complex. In addition, these control schemes have less generality because the appropriate design method of the resonant circuit form the viewpoint in the efficiency is not expressed. Therefore, this paper proposes the design method for the resonant circuit in order to obtain high efficiency, and the maximum efficiency control scheme for the resonant circuit considering the characteristics of an IPT system. The proposed control scheme obtains maximum efficiency easily by controlling the 3 control parameters: the magnitude of the primary-side and secondary-side voltages in the resonant circuit, and the phase between the primary-side and secondary-side voltages of the resonant circuit. In addition, these control scheme and design method are derived from the simple theoretical equations. Eventually, the effectiveness of the proposed design method and control scheme are revealed by the experiments.
