Abstract

With the continuous expansion of wireless power transfer (WPT) in the field of electric vehicles (EVs) and automated guided vehicles (AGVs), there is a need for a wireless charger that can complete the charging of these two devices in a limited space. To fill the gap in this field, this paper proposes an integrated wireless transmitter (IWT) that is suitable for EV and AGV wireless charging under different frequencies, which can realize the radio energy transmission of two types of vehicles in one charging position. It can also tolerate different coupling structures in EV wireless charging, namely the unipolar (Q) and bipolar (DD) coils. The IWT is established by stacking the Q coil and the DD coil composed of two self-decoupled poles, combined with circuit configuration topologies. An experimental prototype is established to verify the interoperability performance. The proposed WPT system can achieve interoperability with EV wireless charging of Q or DD receiving coils at 85 kHz and AGV wireless charging at 200 kHz.

用于EV和AGV的集成无线发射器，具有高互操作性

随着无线电力传输（WPT）在电动汽车（ev）和自动导引车（agv）领域的不断扩展，需要一种能够在有限空间内完成这两种设备充电的无线充电器。为了填补这一领域的空白，本文提出了一种适用于EV和AGV在不同频率下无线充电的集成无线发射器（IWT），可以实现两类车辆在一个充电位置的无线能量传输。它还可以容忍电动汽车无线充电中不同的耦合结构，即单极(Q)和双极（DD）线圈。通过叠加由两个自解耦极组成的Q线圈和DD线圈，结合电路结构拓扑，建立了IWT。建立了实验样机，验证了系统的互操作性。所提出的WPT系统可以与85 kHz的Q或DD接收线圈的EV无线充电和200 kHz的AGV无线充电实现互操作。
