Beschreibung
Zusammenfassung:	A wireless charging device (102) is disclosed. The wireless charging device (102) includes a transmitter detection coil (130) configured to receive a first alternating current (AC) voltage signal having a characteristic associated with a receiver device (104). Also, the wireless charging device (102) includes a control unit (112) coupled to the transmitter detection coil (130) and configured to detect the receiver device (104) based on the characteristic of the first AC voltage signal. Further, the wireless charging device (102) includes a driver unit (108) coupled to the control unit (112) and configured to convert a direct current (DC) voltage signal of an input power to a second AC voltage signal if the receiver device (104) is detected. In addition, the wireless charging device (102) includes a power transmission coil (116) configured to wirelessly transmit the second AC voltage signal to the receiver device (104).
