Document Type and Number:
WIPO Patent Application WO/2024/051086
Kind Code:
A1
Abstract:
Embodiments of the present application provide an electric power receiving device, an electric power sending device, and an electric power transmission method. A battery and protection circuit module is used for acquiring battery impedance; and a first micro-control module is used for sending a driving signal to an impedance conversion module according to a preset optimal value of input impedance of the impedance conversion module and the battery impedance so as to adjust a duty ratio of the driving signal in the impedance conversion module, such that the impedance conversion module outputs a target voltage, wherein the duty ratio is a ratio of a high-level duration of the driving signal in one period to one period, and when the impedance conversion module outputs the target voltage, the input impedance is at the optimal value of the input impedance. According to the present application, load impedance of the electric power receiving device can be controlled at the optimal value in real time, such that the efficiency of the electric power transmission device in the whole transmission state is optimal.
