Abstract
A wireless charging device includes a plurality of power supply modules, a control unit and a charge module. Each of the power supply modules includes a receiver and a conduction circuit. The receiver outputs an induction current. The conduction circuit is coupled to the receiver and generates an output signal according to the induction current. The control unit is coupled to the power supply modules and generates a control signal according to the induction current outputted by the receivers. The charge module is coupled to the power supply modules and generates a charge current according to the output signal generated from the power supply modules. The control unit adjusts the maximum value of the charge current according to the number of the power supply modules which generate the induction current.
