Abstract
A capacitive wireless charging system having a charging circuit and the operating characteristics of the charging circuit can be adjusted. The charging circuit includes two coupling capacitors formed by two electrode plates at least partially overlapping two other electrode plates, where the coupling characteristics of the coupling capacitors can be adjusted by moving at least one of the electrodes. When the coupling characteristics of the coupling capacitors reach a pre-determined threshold, the operating characteristics of the charging circuit can be adjusted to optimize the power transfer efficiency of the capacitive wireless charging system.
