无线电能传输WPT（wireless power transfer）技术可在无人工辅助的条件下为无人机提供灵活便捷的电能补给，是未来无人机智能化发展的重要探索方向。为适应无人机WPT系统轻量化、恒流恒压充电、高能量传输效率等实际需求，提出了1种基于压控电容的无人机WPT系统高效率恒流/恒压输出调节方法。在系统发射线圈回路中采用压控电容作为补偿电容，通过动态调节该压控电容的等效阻抗，可在实现系统输出电流/电压有效控制的同时，保障宽负载范围条件下逆变器的软开关状态，且无需额外辅助电源及电感器件。详细分析了所提无人机WPT系统的工作原理及损耗模型，设计了1套完整的压控电容直流偏置电压调节模块、闭环控制策略及其参数设计方法。实验证明，在25.2 V-6 A的额定输出条件下，系统整体效率达88.8%。

The wireless power transfer (WPT) technology, which can provide flexible and convenient power supply for unmanned aerial vehicles (UAVs) without human assistance, is an important research direction for the intelligent development of UAVs in the future. To meet the practical requirements of lightweight, constant current (CC) and constant voltage (CV) charging, and a high-power transmission efficiency for a UAV-WPT system, a high-efficiency CC/CV output regulating method for the UAV-WPT system based on voltage-controlled capacitor (VCC) is proposed. On the transmitter side, a VCC is utilized as the compensated capacitor. By dynamically adjusting the equivalent impedance of the VCC, the output current and voltage from the system can be effectively controlled. Meanwhile, zero-voltage switching can also be achieved in the inverter in a wide load range without any extra auxiliary power sources or inductors. The operating principle for the proposed UAV-WPT system and its power loss model are analyzed in detail. In addition, a DC bias voltage regulation module, a closed-loop control strategy and a parameter design method for the VCC are designed. Experimental results show that under the rated output conditions of 25.2 V and 6 A, the system’s overall efficiency can reach 88.8%.
