    Abstract: Certain aspects of the present disclosure relate to methods and apparatus for detecting, by a wireless power transmitter, an over voltage protection at a wireless power receiver. Certain aspects of the present disclosure provide a wireless power transmitter. The wireless power transmitter includes a resonator configured to generate a wireless field for wirelessly transferring power to a wireless power receiver. The wireless power transmitter further includes an impedance detector configured to measure an impedance of the resonator. The wireless power transmitter further includes a controller configured to detect operation of an over voltage protection mode of the wireless power receiver based on a frequency of change in impedance as measured by the impedance detector.

    Abstract: Certain aspects of the present disclosure are generally directed to apparatus and techniques for wireless charging. One example apparatus generally includes a plurality of inductive elements and signal generation circuitry coupled to the plurality of inductive elements and configured to generate a plurality of signals, where at least two signals of the plurality of signals have different magnitudes. In certain aspects, the signal generation circuitry is configured to drive the plurality of inductive elements using the plurality of signals, where at least one first inductive element of the plurality of inductive elements is driven using at least one first signal of the plurality of signals having a first phase and at least one second inductive element of the plurality of inductive elements is driven using at least one second signal of the plurality of signals having a second phase different from the first phase.

    Abstract: An aspect of this disclosure is an apparatus for transmitting power wirelessly. The apparatus comprises a detection circuit and a processor. The apparatus also includes a power amplifier driving an antenna circuit of flexible antenna(s) configured for wireless power transfer. The processor determines that at least one measured variable of the power amplifier falls outside of a corresponding threshold range, indicative of a deformation of a physical shape of one of the flexible antennas or indicative of misalignment of the flexible antennas from a power receiver. The processor further commands the power amplifier to transition to a first power mode from a second power mode based on the determination that at least one of the measured variables falls outside of the corresponding threshold range. The antenna circuit in the first power mode transmits power at a power level less than the power level in the second power mode.
