Multi-mode joint modulation of array wireless power transfer

Abstract

In this paper, an array multi-mode wireless power transfer system for UAV is proposed. The system realizes the joint modulation of a single transmitting coil, double transmitting coil, and four transmitting coils in the array wireless power transmission system through PI closed-loop control and realizes the stable output of the WPT system in three different working modes. It effectively compensates for the shortcomings of the single transmitter coil and effectively improves the robustness of the wireless power transfer system.
