Resonant tuning through rectifier time shifting

A device includes support for wireless power transfer. The device may control the timing of switching devices in a rectifier circuit and implement resonant tuning techniques that facilitate the wireless power transfer, e.g., by purposefully introducing a real or complex impedance chosen to meet a cu...

Zusammenfassung:A device includes support for wireless power transfer. The device may control the timing of switching devices in a rectifier circuit and implement resonant tuning techniques that facilitate the wireless power transfer, e.g., by purposefully introducing a real or complex impedance chosen to meet a current operating goal. The device may use the techniques in connection with wireless charging or wireless provision of power to run the device, as examples.
