Abstract
The present disclosure illustrates a bidirectional wireless charging device. The bidirectional wireless charging device comprises a transceiver chip which is configured to receive a switch signal. The transceiver chip comprises a power stage circuit and a control module. The power stage circuit is coupled to a coil, and the control module is coupled to the power stage circuit. The power stage circuit is configured to output a voltage to the coil, or to receive an induced voltage from the coil. The control module is configured to control the transceiver chip to enter a power mode or a charging mode based upon the switch signal. When the transceiver chip enters the power mode, the transceiver chip provides the voltage to the coil. When the transceiver chip enters the charging mode, the transceiver chip receives the induced voltage from the coil and charges a power storage unit.
