Abstract

The elimination of physical conductors as the medium for power transmission is an important approach towards reducing the of waste generated when electronic components and devices are disposed. Besides, the development of wireless power transfer recently has provided an insight for the development of low-power electronic devices and components in less accessible and hazardous environment. This project aims to study and prove the feasibility of impedance matching in wireless power transfer system to extend the operational distance of the system. This project outlined a review of various types of wireless power transfer technology, the various topologies implemented in the wireless power transfer system and the techniques and methods used to enhance the efficiency and the operating distance of the wireless power transfer system. This project starts with an in-depth study on the theory and working principles of the components and the experiments. Besides, the methods on how to conduct the experiments namely constructing different inductor coils, the capacitor to match the designed inductor coils to form a LC oscillator circuit, impedance matching network and the transfer coefficient of the system. Next, the results on determining the best suitable inductor coil for the experiments, the resonance frequency of the LC oscillator circuit and the comparison between the transfer coefficient for both WPT with and without impedance matching were also illustrated. Finally, the WPT system with impedance matching was proven to further increase the power transfer coefficient of the WPT system, for instance, the achieved transfer coefficient at a separation distance of 16cm for both WPT system with and without impedance matching were 0.022 and 0.2158 respectively.
