Abstract: Wireless charging of portable electronic devices is carried out by detecting load variations caused by the device and dynamically compensating for these variations during charging to increase system efficiency and regulate delivered power. In some embodiments, load variations are tracked by comparing a feedback signal to a value range and determining whether the feedback value is higher than, lower than, or within the range of values. This information is then used to modify one or more parameters associated with a power amplifier in a transmitter device.
