Research on Multiload Wireless Power Transfer Characteristics Based on PT Symmetry
In order to solve the problem of the limitation of the PT symmetry region of the original WPT system based on the symmetry principle of the PT symmetry principle S-S,the S-PS topology multiload compensation system based on the PT symmetry principle is adopted.The efficient working range of the system is expanded,and the output power is increased by 50％with the proper capacitance distribution ratio.The magnetic coupler is designed to realize the decoupling between the two receiving coils,which solves the coupling interference problem between the two receiving coils.Simulations verify the effectiveness of the topological circuit,and the decoupling condition of the magnetic coupler is still available under the offset condition.
