Abstract :
A novel method using resonant coils of different sizes is proposed to suppress frequency splitting in wireless power transfer (WPT). Frequency splitting is caused by excessive mutual inductance between transmitter and receiver, and can be suppressed by reasonably designing the sizes of the transmitter and receiver to eliminate the pole value of the mutual inductance. Theory calculation are conducted to present the transfer efficiency of WPT adopting the proposed method. Frequency splitting is remarkably suppressed and transfer efficiency maintains high value.
