Introduction
Wireless power transfer (WPT) is a technology that exploits magnetic, electric or electromagnetic fields to transmit electric power without conductors. This project aims to develop a magnetic WPT system for charging portable devices. The system consists of an oscillator, an amplifier, two coils, a rectifier and the load.
Motivation
The WPT technology has been widely used, especially power charging for portable devices, medical implants and electric vehicles. However, the contradiction between high efficiency, small size and long distance has limited the commercial applications of WPT. Current applications have to sacrifice one of these parameters. Designers should adjust these parameters carefully to meet the requirements of a specified application. Suitable coil design and frequency selection can also improve efficiency without affecting size and distance [1].
