Abstract: The growing demand for efficient and reliable energy transfer systems has driven research into innovative solutions for low-power applications. This thesis focuses on the comparison analysis of inverters for low power application acoustic based energy transfer system. An acoustic energy transfer system is one of promising technology for wireless energy transmission in constrained environments especially in metal environments. The research evaluates the performance of different inverter topologies which are Class E ZVS Inverter and Class D Half Bridge Resonant Inverter by considering key parameters such as efficiency, power transmission, and adaptability to acoustic wave energy systems. Calculation and simulation results from both inverters were compared and Class E ZVS inverter has been chosen for further with experimental because the performance efficiency of Class E produces 98.6% compared to Class D which is 98.04%. The Class E inverter managed to produce better efficiency, power transmission at 40kHz and 470-ohm resistor as an inverter load. The experimental hardware of Class E inverter produces 64.2% as efficiency, as it undergoes tuning process where the tuning processes is critical to optimize the functionality of resonant circuits, ensuring they achieve the best and highest efficiency ii at transmitter. So, the power transmitted to the receiver have some drops due to their internal resistance, and components factor. The receiver will receive 7.36 V at 1cm distance while the target for this project is transmitting to 3cm distance with 6.43V. This shows that the goal of the project to transmit power to the receiving unit has been successfully implemented and it contributes to the progress in wireless power transmission technology.
