Abstract
A bypass control wireless charging device includes a logic control unit electrically connected to a wireless transmission unit, a full-bridge inverter, a buck-boost unit, a discharging switch unit and a back current prevention unit, wherein the discharging switch unit electrically connected to a battery, and a inlet terminal of the back current prevention unit electrically connected to a charging terminal, when the charging terminal electrically connected to an external power, the back current prevention unit turned on by the logic control unit to turned off the discharging switch unit and the input voltage of the external power boosted by buck-boost unit and converted DC to AC by the full-bridge inverter. The coil of the wireless transmission unit provided the emission electricity with AC induction to achieve the purpose of wireless charging for the electronics while received the emission electricity of the wireless transmission unit.
