Abstract | This paper presents multi-megahertz (multi-MHz) wireless power transfer (WPT) technology utilizing integrated printed-circuit-board (PCB) self-resonators, designed for both inductive and capacitive power transfer (IPT and CPT) systems. The PCB resonator comprises a pair of contactless PCB-coil plates incorporating trace inductance and integrated plate capacitance. In IPT systems, the plate capacitances between PCB coils are used to compensate the trace inductances, while the trace inductances are adopted to compensate the plate capacitances in CPT systems. 300W multi-MHz IPT and CPT systems have been developed using 210mm×210mm circular PCB resonators, showcasing stable output current and voltage across a wide range of load variations. A 3MHz IPT system is verified to operate with the maximum efficiency of 90.5% over a relatively long distance of 10cm with strong anti-misalignment but poor anti-load-variation performance. On the contrary, the CPT systems operating at 3.125MHz, 4.68MHz, and 6.78MHz are demonstrated to operate with the maximum efficiencies of 93.14%, 90.56%, and 83.34% over relatively short distances of 6mm, 15mm, and 37mm, respectively, with strong anti-load-variation but poor anti-misalignment performance. |
