Abstract
Example wireless charging methods and apparatus are described. In one example, a wireless charging module includes a control circuit, a charging coil, a tunable capacitor module, and a converter circuit. The converter circuit includes at least one of a rectifier circuit or an inverter circuit. The tunable capacitor module is connected in series between the charging coil and the converter circuit. The tunable capacitor module includes a plurality of capacitors and at least one controllable switch. The control circuit controls the at least one controllable switch to be turned on or off, to control an equivalent capacitance value of the tunable capacitor module. The equivalent capacitance value of the tunable capacitor module includes one of a first capacitance value or a second capacitance value.
