Abstract:
A resonant wireless power (RWP) receiver is provided that includes an inductor element that couples with a resonant wireless power source. A capacitor arrangement is coupled to the inductor element altering the open-circuit impedance of the RWP receiver to reduce the ac voltage under certain defined situations. The capacitor arrangement includes a plurality capacitors tuned to a control ac voltage in the RWP receiver.
