Abstract
A 6.78-MHz fully integrated single-stage wireless
charger with constant-current constant-voltage (CC-CV) charg-
ing technique for resonant wireless power transfer applications
is presented. Based on the principle of three-mode reconfigurable
resonant regulating ( R
3) rectifier, the proposed charger achieves
high efficiency and low cost by realizing power rectification,
voltage regulation, and CC-CV charging in a single power stage.
The power stage of the proposed charger consists of only four
