Adaptive Methods for Efficiency Improvement in Magnetic Resonance based Wireless Power Transmission System

Abstract

Wireless Power Transmission (WPT) is a cutting-edge technology that signifies a new era for electricity without the need of wires. Wireless power or wi-power is increasingly becoming the main interest of many R&D firms to eliminate the “last cable” after the wide public exposure of Wi-Fi lately. Even though the first idea was devised from Nikola Tesla in the early 20th century, there was never strong demand for it due to the lack of portable electronic devices. In recent years, with the advent of a booming development in cell-phones and mobile devices, the interest of wireless energy has been re-emerged. WPT offers the possibility to supplying power for electronic devices without having to plug them into AC socket. In this thesis, all the perspectives about wireless power transfer from basic fundamentals to in-depth analysis are presented. In addition, adaptive methods for efficiency improvement in magnetic resonant WPT system are proposed to lay down the ground work of innovative power technology and open opportunities to commercially implement the advance WPT system in future.
