We propose an approach to eliminate frequency splitting in wireless power transfer (WPT). Two nonidentical resonant coils (NIRCs) are used in this method as power transmitter and receiver, respectively. According to the elliptic integral term in the analytical expression, the pole of the mutual inductance function with respect to transfer distance can be eliminated by using NIRCs. Therefore, frequency...
In this paper, an efficient method is proposed to eliminate frequency splitting in nonradiative wireless power transfer via magnetic resonance coupling. In this method, two nonidentical resonant coils (NIRCs) are used as wireless power transmitter and receiver, respectively. According to the elliptic integral term in the analytical expression, the pole of the mutual inductance function with respect...
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...
