WIRELESS POWER TRANSMISSION APPARATUS USING THE ULTRASONIC

摘要

PURPOSE: A wireless power transmission apparatus is provided to use high power electromagnetic wave without affecting other electronic devices. CONSTITUTION: A power supplier supplies power to a voltage control oscillator(20). The voltage control oscillator generates AC power source. An ultrasound generator(40) generates an ultrasonic signal. An ultrasonic sensor changes the ultrasound to an electric signal. A current sensor senses the current of a load connected to the ultrasonic sensor.
