Abstract

Wireless power transfer has been widely used in unmanned aerial vehicle (UAV) charging due to its convenient and flexible noncontact charging characteristics. The working area of the uncoupler inductive power transfer (IPT) system is limited, and ZVS is easily lost in phase-shift modulation. This paper proposes a method for constant current (CC) /constant voltage (CV) output in an array multitransmitter IPT system based on HFP modulation in a wide working area. The HFP modulation method easily realizes the current phase synchronization of multiple transmitter coils, and the size can be adjusted. At the same time, an efficient optimization model for a multitransmitter IPT system based on HFP modulation is proposed. Finally, an experimental platform for the array multitransmitter IPT system is built to verify the effectiveness of the CC/CV output realization method and the efficiency optimization model for the multitransmitter IPT system. The maximum errors in charging current and voltage are less than 2.52% and 2.1%, respectively, and the peak efficiency of the IPT system reaches 87.3%.

阵列多发射机感应功率传输系统恒流/恒压输出分析与设计

无线充电以其方便灵活的非接触充电特性在无人机充电中得到了广泛的应用。解耦电感功率传输（IPT）系统的工作区域有限，并且在相移调制中容易丢失ZVS。提出了一种基于HFP调制的阵列多发射机IPT系统宽工作区域恒流/恒压输出方法。HFP调制方法容易实现多个发射线圈的电流相位同步，且大小可调。同时，提出了基于HFP调制的多发射机IPT系统的高效优化模型。最后，建立了阵列多发射机IPT系统的实验平台，验证了CC/CV输出实现方法和多发射机IPT系统效率优化模型的有效性。充电电流和充电电压的最大误差分别小于2.52%和2.1%，IPT系统的峰值效率达到87.3%。
