Non-Contact Energy Transfer Based on Ultrasonic
This paper proposed a new method of non-contact energy transmission based on ultrasonic. Firstly describes the work principle of ultrasonic non-contact power transmission, and establishes the model of the system by way of the equivalent circuit, and the system was theoretically analyzed in detail. Then the interface circuit was proposed, and the maximum load power is analyzed. The experiment results show that the energy can be efficiently transmitted within effective distance, indicating that the method has some practical value.
