A bidirectional wireless charging/discharging device for the portable electronic device includes a logic control unit, a boost/buck unit, first and second reverse current suppressors, a control switch, and a receipt/transmission mode selection unit. The logic control unit includes an automatic mode selection resetting module. The reverse current suppressor provide function of reverse current prevention and switching. The boost/buck unit controls stepping up/down of voltage in a charging operation. The logic control unit detects if a load exists and controls the operations of the boost/buck unit and the reverse current suppressor and is used in combination with the control switch to control the performance of charging or discharging and is further used in combination with the receipt or transmission mode selection unit to select a desired mode of operation. The receipt/transmission mode selection unit is electrically connected to automatic mode selection resetting module. |
