Abstract

How to improve the efficiency of IPT systems in the case of transceiver coil misalignment is a core problem that needs to be solved urgently. Compared with single-transmitter IPT systems, multi-transmitter ones exhibit greater power supply flexibility, which ensures stable operation despite misalignment. A topology of a multi-transmitter IPT system is proposed in this study. A grouping and switching control strategy of 3 × 3 multi-transmitter coils is designed on the basis of reconfigurable inverter. A method for charging area division is also put forward to improve the efficiency of the IPT system under the condition of power priority. Compared with the traditional multi-transmitter IPT system, the new multi-transmitter topology proposed in this study can realize the independent operation of each transmitter coil with the minimum number of passive devices.

多发射机 IPT 系统的多模式切换和充电区域划分
如何在收发器线圈错位的情况下提高 IPT 系统的效率,是一个亟待解决的核心问题。与单发射机 IPT 系统相比,多发射机 IPT 系统具有更高的供电灵活性,可确保在错位情况下仍能稳定运行。本研究提出了一种多发射机 IPT 系统拓扑结构。在可重构逆变器的基础上,设计了 3 × 3 多发射线圈的分组和开关控制策略。同时还提出了一种充电区域划分方法,以提高功率优先条件下 IPT 系统的效率。与传统的多发射线圈 IPT 系统相比,本研究提出的新型多发射线圈拓扑结构能以最少的无源器件实现每个发射线圈的独立工作。
