The invention belongs to the technical field of wireless charging, and particularly relates to an unmanned aerial vehicle wireless charging method and device, and the method comprises the following steps: sequentially controlling the connection of each transmitting coil and an inversion module; and when each transmitting coil is connected with the inversion module, the input voltage of a buck module is obtained, the corresponding transmitting coil is set as a working transmitting coil when the input voltage of the buck module is maximum, and the working transmitting coil is controlled to be connected with the inversion module, so that the working transmitting coil transmits power to a receiving coil. When the unmanned aerial vehicle is parked on a charging station, the transmitting coil with the best coupling effect with the receiving coil is selected as the working transmitting coil by judging the maximum voltage value of the buck module, and therefore it is guaranteed that the unmanned aerial vehicle can be wirelessly charged at a high efficiency point under the condition that the system cost is not increased.
本发明属于无线充电技术领域,尤其涉及一种无人机无线充电方法以及装置,无人机无线充电方法包括以下步骤:依次控制各个发射线圈与逆变模块的接通;在各个发射线圈与逆变模块接通,获取buck模块的输入电压,设定在buck模块的输入电压最大时对应的发射线圈为工作发射线圈,并控制工作发射线圈与逆变模块的接通,以使工作发射线圈向接收线圈输电。无人机停靠在充电台上时,通过判断buck模块的电压最大值,选择与接收线圈耦合效果最佳的发射线圈作为工作发射线圈,从而实现在不增加系统成本的情况下,保证无人机能在比较高的效率点上进行无线充电。
