摘要：
This paper proposes a design methodology in a wireless power transfer system for 3-D stacked multiple receivers. A 1:m selective power transfer system is realized by introducing a frequency/time division multiplexing system. The power transfer function is analytically formulated and an optimization methodology of multiple tuning capacitors values is proposed and compared with simulation results. By using the optimized values, power transfer efficiencies at 6.78MHz and 13.56MHz are simulated to be 80% and 84%, respectively. Crosstalk and load transient performance is also compared with 1:1 system and confirmed that its degradation is not significant.
