Abstract

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.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a wireless charging device and method and a mobile terminal using the device. Background technique [0002] At present, mobile terminals (such as mobile phones, tablet computers, etc.) are becoming more and more intelligent, and the screens are getting bigger and bigger, so the power consumption is getting bigger and bigger, and the battery capacity is limited, which requires frequent Charge it. The current mainstream mobile terminal charging technologies include: traditional power adapters (including chargers, charging stations at railway stations and airports, etc.), wireless charging trays and digital charging companions. [0003] The power adapter is the most widely used to charge the battery, but its flexibility is also the worst. It can only be used in fixed environments such as homes and offices, and cannot be used for mobile charging. It needs to be charged by conn...
