Abstract: Recently, wireless power transfer technology has drawn lots of attention because of wire reduction and charging convenience. Previous technologies such as magnetic resonance and induction coupling have drawbacks of short transfer distance and harmfulness to human health. As an alternative, ultrasonic resonance wireless power transfer technology is proposed. A pair of commercial ultrasonic transducer arrays for sensor application is used for wireless power transfer. There are two parameters that have to be decided to maximize the efficiency of power transfer. The first parameter is load resistance that is connected to receiving transducer. It should be matched to the impedance of receiving the transducer at resonance frequency. The second one is the operating frequency of transmitting transducer. It should be matched to the optimal frequency of the receiving transducer. In this paper this optimal load resistance and the frequency of the receiving transducer are analyzed based on circuit theory and verified through experiment.
