Abstract
A wireless charging system includes a wireless power transmitter and N wireless power receivers. The wireless power transmitter includes a power input terminal for receiving an input power, and M transmission modules. Each transmission module includes a power controller, a power management unit, a bridge driver, and a transmission unit. The N wireless power receivers are for receiving N wireless power signals from N transmission units of N transmission modules respectively, and wirelessly transmitting the N communication signals to the N transmission units of the N transmission modules respectively. The M power management units of the M transmission modules are coupled to each other and transmit control signals for handshaking communication.
