Abstract: This application provides a charging pad used in a wireless charger. The charging pad can be wound. Specifically, the charging pad includes a rigid region and a flexible region, and a structure of the rigid region is different from a structure of the flexible region. A rigid support plate is disposed in the rigid region, and a metal line in the flexible region is in a metal hinge structure or is a bendable metal conducting wire. In addition, this application further provides a wireless charger to which the charging pad is applied.

Abstract: This application provides a conversion circuit, a switch-mode power supply, and an electronic device. The conversion circuit mainly includes a first branch circuit and a second branch circuit. Input sides of the first branch circuit and the second branch circuit are connected in series, and output sides of the first branch circuit and the second branch circuit are connected in parallel; or input sides of the first branch circuit and the second branch circuit are connected in parallel, and output sides of the first branch circuit and the second branch circuit are connected in series. This implementation helps improve efficiency of the conversion circuit. When an inductor is disposed in the conversion circuit, a size of the inductor is further reduced, to improve integration.

Abstract: A wireless charging device is disclosed, which includes: a charging pad and a first controller. The charging pad includes a plurality of charging units, the plurality of charging units include a first charging unit and a second charging unit. When a first electromagnetic coupling strength between the first charging unit and the to-be-charged device is greater than or equal to a first threshold, the first controller is configured to control the first charging unit to separately charge the to-be-charged device. When both the second electromagnetic coupling strength between the second charging unit and the to-be-charged device and the first electromagnetic coupling strength are less than a first threshold, and are greater than or equal to a second threshold, the first controller is configured to control the first charging unit and the second charging unit to jointly charge the target to-be-charged device.
