Title:
METHOD AND APPARATUS FOR WIRELESS CHARGING
Document Type and Number:
WIPO Patent Application WO/2022/257087
Kind Code:
A1
Abstract:
The present disclosure relates to a method and apparatus for controlling wireless charging. The method comprises: receiving a first signal representing a peak current or root mean square of an alternating current that flows through a secondary coil; receiving a second signal representing a direct current that is used for charging a load, the direct current being generated by rectifying the alternating current; comparing the first signal with the second signal; and determining, on the basis of a comparison result, whether the current switching frequency of wireless charging is at an ideal switching frequency. If the current switching frequency of the wireless charging is not at the ideal switching frequency, the switching frequency of the wireless charging can be regulated to the ideal switching frequency accordingly, such that the wireless charging is performed at the ideal switching frequency. This can improve the charging efficiency of the wireless charging.
