Bypass Control Wireless Charging Device

A bypass control wireless charging device, comprising:

• a logic control unit;
• a wireless transmission unit, electrically connecting to the logic control unit;
• a full-bridge inverter, electrically connecting to the logic control unit and the wireless transmission unit;
• a buck-boost unit, electrically connecting to the full-bridge inverter and the logic control unit;
• a discharging switch unit, having a battery terminal, a signal terminal, and output terminal, wherein the signal terminal electrically connecting to the logic control unit and the output terminal electrically connecting to the buck-boost unit;
• a battery, electrically connecting to the battery terminal of the discharging switch unit;
• a switch, electrically connecting to the battery terminal with one end thereof, and the other end of the switch electrically connecting to the signal terminal across a first diode;
• and
• a back current prevention unit, having a inlet terminal, a outlet terminal and a control terminal, wherein the inlet terminal electrically connecting to one end of a first resistance and a charging terminal, the other end of the first resistance electrically connecting to the logic control unit and one end of a second resistance and the other end of the second resistance is grounding, the outlet terminal electrically connecting to the discharging switch unit and the buck-boost unit therebetween, and the control terminal electrically connecting to the logic control unit.
