Abstract: Methods and apparatus are disclosed for wirelessly transmitting power. In one aspect, an apparatus (402) for wirelessly transmitting power to power or charge a wireless power receiver is provided. The apparatus comprises a transmitter circuit (204) configured to transmit wireless power via a magnetic field sufficient to power or charge a load. The apparatus further includes a processor circuit (522) configured to determine a power level capability of the transmitter circuit. The apparatus further includes a communication transceiver circuit (532) configured to transmit a first communication to the wireless power receiver (406), the first communication including a request to adjust a power demand from a first power level to a second power level, the first power level being higher than the second power level. The second power level is commensurate with the power level capability of the transmitter circuit.

Abstract: Techniques for reducing reflected reactance in a wireless power transfer system are provided. An example apparatus includes a resonant network including a variable reactance element, such that the resonant network is configured to resonate when the variable reactance element is at a resonant reactance value (C_R), a control circuit operably coupled to the variable reactance element and configured to determine a first reactance value (C_1) and a second reactance value (C_2), such that an output of the PRU is the desired output (V_1) when the variable reactance element is either the first reactance value (C_1) or the second reactance value (C_2), and the first reactance value (C_1) is below the resonant reactance value (C_R) and the second reactance value (C_2) is above the resonant reactance value (C_R), determine an indication of a source reactance associated with a wireless power source, and adjust the variable reactance element to either the first reactance value (C_1) or the second reactance value (C_2) based on the indication of the source reactance.
