<p>The present invention relates to the technical field of communications. Provided are a wireless charging device and method, and mobile terminal using the same independent of a fixed power grid for power charging, thus making charging more flexible. The device comprises: a bidirectional transducer and controller, the bidirectional transducer being used to convert direct current of a direct-current power supply into alternating current, and to transmit, via electromagnetic induction coupling, alternating current to a device to be charged so as to charge the device; or being used to receive the alternating current from a power supply device via electromagnetic induction coupling, and convert the received alternating current into direct current so as to charge the direct-current power supply. The present invention is suitable for charging devices such as a mobile terminal.</p> |
