Patent Images
1. A charging apparatus for efficient wireless charging of a mobile terminal, comprising:
- at least one sensor for detecting the mobile terminal;
a Radio Frequency (RF) receiver for receiving a unique identifier of the mobile terminal from the mobile terminal and determining if the mobile terminal is a rechargeable device;
a power supply unit for receiving an alternating voltage from an external power source and transmitting the received alternating voltage;
at least one modulator for directly applying the alternating voltage received from the power supply unit to a first coil, or converting the alternating voltage received from the power supply unit to a direct voltage and applying the converted direct voltage to the first coil; and
a controller for controlling whether to convert the alternating voltage received from said at least one modulator.
