Development of class D inverter for acoustics energy transfer implantable devices

Abstract :

The working principle of half-bridge Class D Parallel-Resonant Inverter (PRI) as power amplifier is presented in this paper. Simulation of the model is carried out using Proteus. In order to verify the simulation results, an experimental verification is done. This inverter used to excite PZT transducers at suggested resonant frequency of 416 kHz with power level transferred through Acoustics Energy Transfer (AET) concept at about 80 mW. As experimental outcome result, the system managed to transfer energy of 66 mW to the receiver side. © 2016 Institute of Advanced Engineering and Science. All rights reserved.
