摘要： In a wireless power transfer system with multiple receivers, receiver management may be necessary to effectively provide power to the multiple receivers. In one implementation, receiver management includes sweeping or stepping the transmitter resonant and/or operating frequency. In another implementation, receiver management includes receiver self-management, in which the receiver load current duty cycle is controlled to maintain receiver voltage even in the presence of multiple receivers. In another implementation, receiver management includes receiver self-management, in which one or more receivers use a time-sharing heuristic to identify when other receivers are charging and wait to begin receiving a transfer of power until another receiver has stopped receiving a transfer of power.

The system includes a system control loop and a plurality of local control loops. The system control loop comprises a system operating frequency, and each local control loop comprises a corresponding local operating frequency. Each of the local operating frequencies is spaced apart from the system operating frequency by at least a predefined distance. For a particular embodiment, a settling time corresponding to the local operating frequency of each local control loop is at least five times faster than a time constant corresponding to the system operating frequency.

摘要： A system includes multiple photovoltaic panels having a combined output profile that defines energy or power generated by the photovoltaic panels over time. Each photovoltaic panel is configured to generate a peak amount of energy or power at a different time. The system also includes a storage device having a charging profile and configured to be charged by the photovoltaic panels. The charging profile defines a maximum amount of energy or power sinkable by the storage device at a given time. The output profile and the charging profile are substantially matched such that a maximum level of the output profile is approximately equal to the maximum amount of energy or power sinkable by the storage device. The maximum level of the output profile could be substantially constant over time between first and second peak amounts of energy or power generated by different photovoltaic panels.

A tunable parameter may be capacitance, inductance, or frequency.A metric related to power transfer from the transmitter through a coil is used to determine an amount to modify a parameter.
