Wireless power transfer system : development and implementation

Thesis Abstract

Abstract
Wireless power transfer (WPT) technology is a cutting-edge area of research that aims to revolutionize the way electronic devices are powered. This project focuses on the development and implementation of a wireless power transfer system. The main objective is to design a system that can efficiently transfer power wirelessly over a certain distance, eliminating the need for traditional wired connections. The project involves the design and optimization of the transmitter and receiver units to ensure high efficiency and reliability of power transfer. Various methods of wireless power transfer, such as inductive coupling, magnetic resonance, and radio frequency (RF) energy harvesting, are explored and compared to determine the most suitable approach for the system. Key components of the wireless power transfer system include the power source, transmitter circuitry, transmission medium, receiver circuitry, and load. The power source could be a battery, solar panel, or any other energy harvesting device. The transmitter circuitry is responsible for converting the input power into a suitable form for wireless transmission. The transmission medium, which could be electromagnetic fields or radio waves, facilitates the transfer of power from the transmitter to the receiver. The receiver circuitry then converts the received power back into a usable form for the load. Efficient power transfer is achieved through careful design and optimization of the system components. Factors such as distance between transmitter and receiver, alignment, coil design, resonance frequency, and power conversion efficiency are critical in ensuring successful power transfer. The project also addresses challenges such as energy loss, interference, and safety concerns associated with wireless power transfer systems. The implementation of the wireless power transfer system involves practical testing and validation of the designed system. Experimental results are used to evaluate the performance of the system and identify areas for improvement. Real-world applications of wireless power transfer, such as charging electronic devices, powering sensors in remote locations, and electric vehicle charging, are explored to demonstrate the potential impact of this technology. Overall, the development and implementation of a wireless power transfer system offer a promising solution for a wide range of applications where traditional wired power connections are impractical or inconvenient. By enabling efficient and reliable power transfer without physical connections, wireless power transfer technology has the potential to revolutionize the way we power electronic devices in the future.
