Document Type and Number:
WIPO Patent Application WO/2020/124573
Kind Code:
A1
Abstract:
Provided are a transmitting apparatus, a receiving apparatus, a power supply device and a wireless charging method. The transmitting apparatus comprises: a wireless transmitting circuit for transmitting a wireless charging signal; and a communication control circuit for receiving a first feedback signal from a receiving apparatus, and sending, according to the first feedback signal, a second feedback signal to a power supply device, wherein the first feedback signal is a feedback signal corresponding to an output current of a wireless receiving circuit, and the second feedback signal is used for triggering the power supply device to adjust an output voltage and/or an output current of the power supply device. In the technical solution, the transmitting apparatus can control the output voltage and/or the output current of a power supply device according to the feedback of the output current of a wireless receiving circuit, so as to control the output current of the wireless receiving circuit, such that the amount of heat generated by the wireless receiving circuit can be controlled.
