Abstract

The new engineering concepts involved in wireless power transfer systems were discussed in this study Wireless Power Transfer (WPT). In contrast to the existing WPT systems of inductive power transfer (IPT) and capacitive power transfer (CPT), a new alternative methodology called acoustic energy transfer (AET) is offered. In order to transfer electricity from the transmitter unit to the reception unit, the AET system uses vibration or sound waves propagation. This project focuses on power conversion performance in a Class E ZVS inverter at the transmitter unit, as well as the appropriate circuit developed for impedance matching to overcome impedance variance. Furthermore, this work also includes on previous study proven that the AET system had several advantages compare to IPT and CPT. Moreover, there are further explanation on WPT techniques and theory related to circuit design. Next, the methodology that being used in the process will give an explanation on the overall simulation results regarding to the simulation. Lastly, the conclusion and recommendation for further development is suggested.
