Ultrasonic wireless power transmitter and receiver apparatuses, and method for wireless charging thereof |
摘要 |
Disclosed are ultrasonic wireless power transmitter and receiver apparatuses, and a method for wireless charging thereof. A method for wireless charging according to the present disclosure includes: transmitting, by an ultrasonic wireless power transmitter apparatus, an wakeup signal to an ultrasonic wireless power receiver apparatus; calculating, by the ultrasonic wireless power transmitter apparatus, a charging time according to a charging status information received from the ultrasonic wireless power receiver apparatus; generating, by the ultrasonic wireless power transmitter apparatus, an ultrasonic signal, amplifying the generated ultrasonic signal to predetermined voltage and thereafter; charging, by the ultrasonic wireless power transmitter apparatus, the ultrasonic wireless power receiver apparatus for the calculated time and thereafter; and determining, by the ultrasonic wireless power transmitter apparatus, whether secondary charging is to be performed according to a charged status information received from the ultrasonic wireless power receiver apparatus. |

1. An ultrasonic wireless power transmission apparatus, comprising:
an ultrasound generating unit configured to generate an ultrasonic signal for transmitting electric power; a signal processing unit configured to modulate the ultrasonic signal; a power amplifying unit configured to amplify the modulated ultrasonic signal to a predetermined magnitude; an ultrasonic transmitter/receiver unit configured to send the power-amplified ultrasonic signal to an ultrasonic wireless power receiver apparatus or receive the power-amplified ultrasonic signal from the ultrasonic wireless power transmitter apparatus; and a control unit configured to calculate a charging time using power amount data received from the ultrasonic wireless power receiver apparatus and calculate a natural frequency using a distance to the ultrasonic wireless power receiver apparatus and a size of a radiation plate of the ultrasonic transmitter/receiver unit. |
