Abstract

This report presents the study of the wireless power transfer device carried out for Final Year Project 2. The purpose of this project is to construct the wireless power transfer (WPT) module with different combination of winding turns of primary and secondary windings. Indeed, this project aims to design, construct and program a single phase inverter to inject variable frequency AC signal to wireless power transfer module. The main factor of this project problem is the presence of complicated, cumbersome and dangerous wires cable in certain devices and appliances used in the daily life. In the construction of WPT system, the methodology of the project is divided into design and develop a WPT device and single phase inverter. The design of the single phase inverter is divided into two part which are software and hardware development. The single phase inverter circuit and PCB layout is design and the initial part of the programming part of the system is well described. After the construction of this project, the basic principle of WPT system is being studied and applied. By conducting experiments in the laboratory, measurement data is collected and analysed. This paper describes the construction of a prototype as well as the complete schematic of the prototype. The RL characteristics of the WPT is analysed. The experiment starting with the hardware fabrication of the WPT module and the single-phase inverter.To summarize the results, it capable of constructing a wireless power transmission structure. When making the WPT module, distinct parameters are used in both the primary and secondary coils.The findings of the experiment reveal that the frequency and air gap have an impact on the inductance and resistance of the module
