Abstract:

Wireless charging of automated guided vehicles (AGVs) has been widely used because of its high security and convenience. However, due to the inevitable misalignment between the coupling coils, the charging system cannot maintain the constant current (CC) or constant voltage (CV) output. Therefore, this article proposes a misalignment-tolerant fractional-order wireless power transfer (FOWPT) system with CC or CV output. According to the principle of the fractional-order autonomous circuit, the natural resonant frequency and operating frequency can be adjusted adaptively with the change of transfer distance and load. Benefiting from the frequency characteristics and the new implementation method of the FOWPT, the system maintains CC and CV output, and the horizontal and vertical misalignment tolerances are within 44.4% and 22.2%, respectively. Therefore, the proposed system improves the freedom and convenience of charging, and provides a new wireless charging solution for AGVs. Future article will focus on more concise modeling and implementation methods of fractional-order systems, and improving the performance of the FOWPT.
