A remote wireless charging transmit end is configured to wirelessly charge a receive end. The transmit end includes a transmit end processor, a fundamental frequency-radio frequency conversion unit, and a transmit end antenna. The transmit end processor is configured to generate a composite signal based on a control signal and a power signal, and send the composite signal to the fundamental frequency-radio frequency conversion unit. The control signal is used to control a working status of the receive end, and the power signal is used to charge the receive end. The fundamental frequency-radio frequency conversion unit is configured to convert the composite signal into a radio frequency signal, and send the radio frequency signal to the transmit end antenna. The transmit end antenna is configured to transmit the radio frequency signal corresponding to the composite signal.

Remote wireless charging transmit end, receive end, 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.

Transmit end supporting multi-device wireless charging, charging base, and system

A wireless charging receiving apparatus of a mobile terminal. The wireless charging receiving apparatus is configured to be disposed inside the mobile terminal and close to a metal rear housing of the mobile terminal, and includes two interconnected coils. The two coils are located in a same plane and are connected in series, and winding directions of the two coils are opposite, so that directions of magnetic fluxes generated by the two coils on the metal rear housing are opposite, thereby resolving a problem of an eddy current on the metal rear housing of the mobile terminal such as a smartphone including a wireless charging system, and reducing a temperature of a metal body and reducing an energy loss without forming a hole or a seam on the metal rear housing.

Wireless charging receiving apparatus, transmitting apparatus, and system of terminal

A wirelessly charged electronic device, a wireless charging method, and a wireless charging system are disclosed. A charger of a receive end of the system includes an open-loop DC-DC (direct current-to-direct current) converter. When power of a transmit end is greater than a first preset threshold of the transmit end and required charging power is greater than a first preset threshold of a receive end, the open-loop DC-DC converter is controlled to work in a fast charging phase, specifically including: controlling the open-loop DC-DC converter to work in a constant current step-down phase to charge a battery at a constant current, or controlling the open-loop DC-DC converter to work in a constant voltage step-down phase to charge the battery at a constant voltage.
