Abstract
An apparatus for wireless power transfer is described. In some implementations, the apparatus includes a resonant circuit configured to receive a radio frequency input and generate an in-phase voltage and an out-of-phase voltage. The apparatus further includes a pulse generation circuit configured to at least gate the in-phase voltage to provide a first output voltage, and gate the out-of-phase voltage to provide a second output voltage. The apparatus further includes a pulse width modulation circuit configured to provide, to the pulse generating circuit, information for controlling the pulse width modulation setting. The apparatus further includes a pulse frequency modulation circuit configured to provide, to the pulse generating circuit, information for controlling the pulse frequency modulation setting, the information for controlling the pulse frequency modulation setting determined based on the pulse width modulation setting. Related systems, methods, and articles of manufacture are also described.
