    Abstract

    This paper proposes a wireless power transfer system which switches between a single frequency mode and a dual frequency mode for 3-D stacked multiple receivers. The power transfer function is analytically formulated in each mode and an optimization methodology of tuning capacitor values is proposed in both modes. An operation scenario switching between two modes is presented and compared with the non-switching mode in terms of the power transfer efficiency. The average power transfer efficiency in the proposed mode is 9.5% higher than the conventional mode.
