TRANSMITTING TERMINAL SUPPORTING WIRELESS CHARGING OF MULTIPLE DEVICES, CHARGING BASE AND SYSTEM

This application discloses a transmit end supporting multi-device wireless charging, a charging base, and a system, to support N-channel wireless charging, where N is an integer greater than or equal to 2. The transmit end includes N half-bridge inverter circuits, a multi-coil gating matrix, and a multi-coil module. Input terminals of the N half-bridge inverter circuits are connected to corresponding direct currents, and output terminals of the N half-bridge inverter circuits are connected to input terminals of the multi-coil gating matrix. The multi-coil gating matrix includes a plurality of switching switches, configured to respectively connect the output terminals of the N half-bridge inverter circuits to corresponding transmit coils in the multi-coil module. Compared with a full-bridge inverter circuit, in the half-bridge inverter circuit, a quantity of bridge arms is reduced by 1, and a quantity of switching transistors is reduced by half. A quantity of switching transistors in a next-stage gating matrix may also be reduced by half correspondingly. When the quantity of switching transistors is reduced, a quantity of corresponding control signals is also reduced. Therefore, both hardware control and software control are simplified, thereby reducing a quantity of hardware, and reducing a size of a circuit board. After the quantity of control signals is reduced, control reliability can be improved.
