Abstract
A wireless charging device includes a power source configured to generate a direct current (DC) voltage signal. Also, the wireless charging device includes a driver unit configured to receive the DC voltage signal and convert the DC voltage signal to a first alternating current (AC) voltage signal. Further, the wireless charging device includes a transmitting unit including a resonant capacitor and a resonant coil, coupled to the driver unit, wherein the transmitting unit is configured to receive and transmit the first AC voltage signal. Additionally, the wireless charging device includes a control unit configured to detect a receiver device based on a change in at least one of a capacitive voltage across the resonant capacitor and an inductive voltage across the resonant coil if the receiver device is positioned within a predetermined distance from the transmitting unit.
