人们对无线电能传输(WPT)的需求越来越大，方法也越来越多。在这项研究中，我们重点研究了一种适合于大功率电源的电磁感应方法，因为它被认为是为电动汽车充电的。电磁感应法的一个问题是传输功率随着线圈之间距离的增加而下降。作为这一问题的解决方案，人们期待新的估计方法和控制方法。本研究利用电机驱动的矢量控制理论，从另一个角度讨论了三相WPT系统的运行特性。仿真结果显示了WPT系统在旋转d-q坐标系下的运行特性。
There is an increasing demand for wireless power transmission (WPT), and there are multiple methods. In this study, we focus on an electromagnetic induction method suitable for high-power power supply because it is supposed to charge EVs. A problem with the electromagnetic induction method is that the transmission power drops as the distance between the coils increases. As a solution to this problem, new estimation methods and control methods are expected. This study discusses operating characteristics of a three-phase WPT system from another approach, using vector control theory of motor drives. The simulation results show the operating characteristics of the WPT system in a rotating d-q reference frame.
