Abstract: A wireless power receiver comprises a resonant tank configured to generate an AC power signal responsive to an electromagnetic field, a rectifier configured to receive the AC power signal and generate a DC output power signal, and control logic configured to control the resonant tank to reconfigure and adjust its resonant frequency responsive to a determined transmitter type of a wireless power transmitter. The control logic may operate the wireless power receiver as a multimode receiver having a first mode for a first transmitter type and a second mode for a second transmitter type. The resonant tank may exhibit a different resonant frequency for each of the first mode and the second mode. A method comprises determining a transmitter type for a wireless power transmitter desired to establish a mutual inductance relationship, and adjusting a resonant frequency of a resonant tank of a wireless power receiver.
