Abstract

Described herein is wireless energy transmission via magnetic resonant coupling for author’s FYP project. The idea is based on two resonant coils, with one acting as transmitter, which consist of source and circuit, and the other as receiver connected to load, such as low power LED, having strong coupling electromagnetic resonant for wireless energy transmission from transmitter to receiver over a certain distance. The working principle operates as traditional inductance magnetic coupling devices, where Faradays’ Law states that, a time varying magnetic field of a coil of wire, voltage (emf) will be induced in the coil. However, these principles will limit the efficiency and distance transfer between transmitter and receiver. Thus, by applying resonant concept, which tunes both objects operating frequencies into resonant frequency, we can transfer energy wirelessly with greater efficiency and longer distance. This paper will emphasize on the fundamental principle in order to realize the concept until the design of the prototype itself. The basic theory such as magnetic induction, resonant frequency as well as magnetic resonant coupling will be further explained for better understanding and clarification. Apart from that, further analysis will also discussed and compared with the achievement and work done by others in comprehensive literature review chapter. In the design of prototype, a number of calculations have been done in order to get the resonance frequency which can be applied to both coils to function and the process of designing the circuit and building it through exclusive studies, will also be explained in detail. Last but not least, author will further analyze the circuit comprehensively by studying on three most important results, which are voltages, magnetic field intensities, and power with respect to different parameter setting. The author compared the finding by using theoretical calculation and measurement by using spectrum analyzer and multi-meter. All the measurement will be tabulated in tables and graphs.
