A Development of Acoustic Energy Transfer System through Air Medium Using Push-Pull Power Converter
Authors: , , , , ,
Abstract: This paper presents a development of Acoustic energy transfer (AET) system through air medium using push-pull power converter. The push-pull converter may operate under zero voltage switching condition at resonance frequency and capable to minimize switching losses. This paper investigates the performance of AET through the air by using ceramic disc ultrasonic transducer, specifically for low power applications. A multiple input-output transducer is also designed in this paper. The simulation and experimental works are carried out and the obtained results are analysed accordingly. Based on the experimental results, the 1.07mW output power is obtained at 40kHz operating frequency. The multiple transceiver design offers 100% efficiency of energy transmission which is 7.24mW output power.
