摘要：

Array dynamic wireless power transfer system is proposed because of its advantages of lower operating loss and magnetic flux leakage and better flexibility, and its operation characteristics depend on the structures of transmitting array and receiving coil. A coil switching method based on LCC-S compensa-tion topology is proposed to reduce the mutual inductance drop and minimize its mutation at switching moments so that the misalignment tolerance of the system can be improved. Meanwhile, the performances of single-layered and double-layered transmitting array systems after applying the proposed switching method are compared. Simulative results show that although the switching control of double-layered transmitting array system is more complex, its output power drop is smaller and the misalignment tolerance is higher when there is misalignment between transmitting and receiving coils. Experimental results verify that the proposed coil switching method is effective and feasible in practice. © 2022 Electric Power Automation Equipment Press. All rights reserved.
