Abstract:
An apparatus and method are disclosed to control the mutual coupling between wireless power transfer (WPT) enabled devices. Wireless power transfer is best achieved when both the transmitting and receiving device are tuned to substantially the same frequency. Because WPT-enabled devices are coupled to one another during WPT, tuning one WPT-enabled device can cause both devices to converge to a resonance together. Furthermore, a WPT enabled receiving device can be intentionally detuned to avoid coupling excessive power from a WPT-enabled transmitter device. These concepts can be extended to WPT-enabled device pairs that each has WPT transmission and reception qualities. When multiple WPT-enabled devices interact, tuning information can be stored in one or both of the devices to make the configuration procedure for subsequent WPT interactions more efficient. Various systems are presented to control the mutual coupling between WPT-enabled devices to improve the WPT.
Abstract:
An apparatus and method are disclosed to increase the efficiency of communications between wireless power transfer (WPT) devices. During an initial power transfer and/or communication between WPT devices, characteristics regarding the operation and capabilities of the devices are shared and stored on one or both of the WPT devices. On subsequent power transfers and/or communications, a WPT device can quickly match the capabilities and preferences for the same WPT device. Various systems are presented to generate, access, and implement the stored information to quickly tailor and improve a communication session for a specific WPT device.
