Wireless charging device and control method thereof

摘要

There are provided a wireless charging device and a control method thereof, the wireless charging device including: a first receiving module receiving power from the outside in a magnetic induction scheme to thereby charge a battery; a second receiving module receiving power from the outside in a magnetic resonance scheme to thereby charge the battery; a switching unit performing a switching operation at a preset interval such that one of the first receiving module and the second receiving module is selected; and a switching controlling unit receiving a stop signal or an operating signal from one of the first receiving module and the second receiving module to thereby control the switching operation of the switching unit.

1. A wireless charging device, comprising:
a receiving coil; a first receiving module configured to receive power in a magnetic induction scheme from the receiving coil; a second receiving module configured to receive power in a magnetic resonance scheme from the receiving coil; a switching unit configured to repeatedly change between a first connection state, in which the first receiving module is electrically connected to the receiving coil, and a second connection state, in which the second receiving module is electrically connected to the receiving coil; and a switching controlling unit configured to receive a stop signal or an operating signal from whichever one of the first receiving module and the second receiving module is electrically connected to the receiving module, wherein the first receiving module is further configured to, in response to being connected to the receiving coil, compare an operating frequency band of the received power and a preset first frequency band, provide the stop signal to the switching controlling unit in response to the operating frequency band matching the first frequency band, and provide the operating signal to the switching controlling unit in response to the operating frequency band not matching the first frequency band, and the second receiving module is further configured to, in response to being connected to the receiving coil, compare an operating frequency band of the received power and a preset second frequency band, provide the stop signal to the switching controlling unit in response to the operating frequency band matching the second frequency band, and provide the operating signal to the switching controlling unit in response to the operating frequency band not matching the second frequency band.
