THERMAL BARRIER FOR WIRELESS POWER TRANSFER Russian patent published in 2018 - IPC H02J5/00 H05B6/06 

FIELD: electrical equipment.

SUBSTANCE: invention relates to electrical equipment. Technical result is achieved due to the fact that a thermal barrier for a wireless power transfer system comprises first surface area (807) for coupling to power receiver (111) to be powered by a first electromagnetic signal and second surface area (805) for coupling to power transmitter (101) providing a second electromagnetic signal. Thermal barrier (801) further comprises power repeater (803) with a resonance circuit including an inductor and a capacitor. Power repeater (803) is arranged to generate the first electromagnetic signal by concentrating energy of the second electromagnetic signal towards first surface area (807). Thermal barrier may provide thermal protection of power transmitter (101) without unacceptable impact on the power transfer operation.

EFFECT: improved security and reliability of wireless power transmission.
