Document Type and Number:
WIPO Patent Application WO/2023/138322
Kind Code:
A1
Abstract:
The present application relates to the technical field of terminals. Provided are a transmitting end for wireless charging, a charging base, and a system. The transmitting end comprises an inverter circuit, n transmitting coils, a suppression circuit and a controller, wherein n is an integer greater than or equal to 2; each of the n transmitting coils is connected to an output end of the inverter circuit; the inverter circuit is used for converting a direct current into an alternating current and transmitting the alternating current to at least one of the n transmitting coils; at least one of the n transmitting coils operates, and the remaining transmitting coils do not operate; and the controller is used for grounding, by means of the suppression circuit, the transmitting coils which do not operate, so as to suppress conducted emission and radiated emission of the transmitting coils which do not operate, that is, the conducted emission and radiated emission of the transmitting coils which do not operate are transmitted to the ground, thereby reducing the conducted emission and radiated emission of the transmitting coils which do not operate, and thus suppressing, on the whole, an interference signal generated by the transmitting end.
