Abstract

Inspired by original work of Nikola Tesla in resonant inductive coupling, numerous investigations are going on making wireless power transfer (WPT) application an optimum choice for various fields. By implementing the concept of non-radiative magnetically-coupled resonant circuits, it has been found that wireless power transmission is achievable at room-scale. This thesis investigates various aspects of the possibilities of room-scale wireless power transfer. Firstly, following the background of WPT systems, MATLAB-coil design, calculation of mutual inductances and Excel-calculation of WPT system performance in multi-resonator systems design tools for WPT systems are discussed for estimating the performance of numerous WPT resonator networks at room-scale. Secondly, the WPT system with two transmitters and a load receiver was simulated for measuring resonator parameters and flux-coupling coefficients between inductors using MATLAB and excel computational tools. Also, the WPT network of four-transmitter coil system was proposed to overcome the shortcomings of two-transmitter coil system xiii incapable of transmitting power efficiently at the various orientation of receiver coil. The goal of this design was to permit greater flexibility in angular position, or attitude of the receiver coil at the room space. The simulated results were found to be promising for room-scale wireless power transmission. The chapter concludes with a design validation that is efficient for a room-scale wireless power transmission. Conclusions and suggestions for future work are provided.
