摘要

Nowadays, automated guided vehicle (AGV) has been a key role of manufacturing and logistics, required to work with high automation. It is essential to guarantee the charging reliability of AGV for all-day work. However, in wireless battery charging applications, to utilize load-independent-current and load-independent-voltage transfer characteristics for constant current (CC) and constant voltage (CV) outputs respectively, existing inductive power transfer (IPT) converters either hopping the operating frequencies or switching the hybrid compensation topologies, resulting in necessity of state-of-charge detection and feedback control for the operating frequency hopping or the compensation topology switching. To improve the charging reliability of AGV by eliminating these active controls, this paper proposes an IPT converter with inherent CC-to-CV transition ability that can comply with the required charging profile of the batteries. Unity-power-factor design is also considered to minimize the voltage-ampere rating. This solution is passive, and control is unnecessary, so donating great reliability in automated guided vehicle. Experimental results are presented to verify the methodology and the performance.1
