THERMAL BARRIER FOR WIRELESS POWER TRANSFER |
| 摘要 |
A thermal barrier for a wireless power transfer system comprises a first surface area (807) for coupling to a power receiver (111) to be powered by a first electromagnetic signal and a second surface area (805) for coupling to a power transmitter (101) providing a second electromagnetic signal. The thermal barrier (801) further comprises a power repeater (803) with a resonance circuit including an inductor and a capacitor. The power repeater (803) is arranged to generate the first electromagnetic signal by concentrating energy of the second electromagnetic signal towards the first surface area (807). The thermal barrier may provide thermal protection of the power transmitter (101) without unacceptable impact on the power transfer operation. |

1. A thermal barrier for a wireless power transfer system, the thermal barrier comprising:
a first surface area for coupling to a power receiver to be powered by a first electromagnetic signal; a second surface area for coupling to a power transmitter providing a second electromagnetic signal; a power repeater comprising a resonance circuit including an inductor and a capacitor, the power repeater being arranged to generate the first electromagnetic signal by concentrating energy of the second electromagnetic signal towards the first surface area; a receiver for receiving a temperature measurement; and a controller for controlling a first level of the first electromagnetic signal by adapting a property of the resonance circuit, the controller being arranged to reduce the first level for increasing values of the temperature measurement. |
