TRANSMIT END SUPPORTING MULTI-DEVICE WIRELESS CHARGING, CHARGING BASE, AND SYSTEM

A transmit end for multi-device wireless charging 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 switches configured to respectively connect the output terminals of the N half-bridge inverter circuits to corresponding transmit coils in the multi-coil module.
