Abstract: Optimal inductance and capacitance values of a receiver (Rx) LC matching network are proposed in order to maximize the efficiency of capacitive wireless power transfer (CWPT). To maximize the overall Tx-to-load efficiency, a general polynomial equation is proposed that gives an optimum Rx inductance and capacitance value under the given constraints of inductor losses, load impedance, and coupling capacitance. It is found that the efficiency is maximized when the Rx input resistance is approximately equal to th… Show more

“…The thin configuration of the metal plates results in a compact coupling interface that is simple to establish with the devices. For optimal power transfer, the small capacitance between the two parallel plates gives the reactance compensation an essential role in coupling [59]. Figure 5 shows the main components of the CC-WPT system, which involves converting DC voltage to high-frequency AC voltage to supply two primary metal plates using a high-frequency inverter [60].…”

“…Both inductive and capacitive power transfer technologies are investigated in drone charging applications [252]. Considering CPT applications, the receiver side of the system is minimized to ensure compatibility [253,254], and to obtain the maximum efficiency [255]. A capacitive coupler design is proposed to decrease parasitic capacitances with a rotational misalignment capability [113,256].…”
