Abstract
In certain aspects, methods and systems for converting DC power to AC power by a wireless power receiver are disclosed. Certain aspects provide a wireless power receiver including a resonant circuit. The wireless power receiver includes a first switching circuit coupled to the resonant circuit, the first switching circuit configured to act as an inverter and generate a first signal, based on an output from a battery, at a resonant frequency of the resonant circuit, the first signal having an envelope at a first frequency. The wireless power receiver includes a second switching circuit coupled to the resonant circuit that is configured to bias the second switching circuit at the resonant frequency in response to the first signal, wherein the second switching circuit is configured to act as a rectifier and is configured to extract the envelope to generate a second signal at half of the first frequency.
