There is a conflict between the energy transfer efficiency and maximum transferred power in conventional inductive power transfer (IPT) systems, and the energy transfer efficiency is only 50% when maximum power is transferred. To solve this problem, a new topology which is operated at switched-mode is proposed in this paper. The high frequency current of the topology is generated by the free oscillation...
Inductive power transfer employing high quality factor (high- $Q$) resonators is an effective method to extend the transfer range of the wireless power transfer system. However, the overenhanced loading effect on the transmitter side exacerbates the degradation of power transfer capability and the phenomenon of frequency splitting at a short coupling distance. Currently, range adaptation techniques...
