System for transferring wireless power using ultrasonic wave
First Claim
1. A system of transferring wireless power using an ultrasonic wave, the system comprising:
- an ultrasonic wave generating device configured to convert electric energy into an ultrasonic wave and transfer the ultrasonic wave; and
an ultrasonic wave receiving device configured to receive the ultrasonic wave and convert the ultrasonic wave into electric energy,wherein the ultrasonic wave generating device comprises a radiation plate, which includes a plurality of ultrasonic elements, and adjusts an effective area of the radiation plate by selectively turning on/off the plurality of ultrasonic elements so that a beam of the ultrasonic wave is substantially focused at a position where the ultrasonic wave receiving device is allocated, andwherein the ultrasonic wave generating device selects a center point of the effective area that corresponds to the position of the ultrasonic wave receiving device, and turns on some of the ultrasonic elements around the selected center point while keeping the rest of the ultrasonic elements turned off.
