WIRELESS BATTERY CHARGING SYSTEM USING RADIO FREQUENCY ENERGY HARVESTING



INTRODUCTION AND MOTIVATION

Cellular telephone technology became commercially available in the 1980 s. Since then, it has been like a snowball rolling downhill, ever increasing in the number of users and the speed at which the technology advances. When the cellular phone was first implemented, it was enormous in size by today s standards. This reason is two-fold; the battery had to be large, and the circu ....etc

A fluid queue modulated by two independent birth death processes

ABSTRACT
We present a fluid queue model driven by two independent finite state birth death processes with the objective to study the buffer occupancy distribution in any intermediate node in a communication network. In a communication network, at any node, the arrival and service of the packets are with variable rates. To mo ....etc

Abstruct-
Analysis, design, and implementation of the space vector modulated three-phase to three-phase matrix converter with input power factor correction are presented. The majority of published research results on the matrix converter control is given an overview, and the one, which employs sheous output-voltage and input-current space vector modulation, is systematically reviewed. The modulation algorithm is theoretically derived from the desired average transfer fu ....etc

Abstract
A benchmark system for studying the sinusoidal pulse-width-modulated distribution-static synchronous compensator (D-STATCOM) is proposed. A simple multifunction controller is provided to offer dc bus voltage control, power factor correction, and ac voltage control. Simulation results are presented and compared to experimental results obtained from a 10-kVA laboratory D-STATCOM. Excellent agreement between simulation and experimental results is obtained, ....etc

Ambient Power Harvesting: Ubiquitous radio signals mean there is energy in the air being used to transmit information. By analyzing the spectrum and nding the channels on which there is the most power and which are most available in many areas we could determine whether it is feasible to power a small device using signals already in the air. We could also research applications which would best be able to take advantage of such a system. ....etc

Abstract

It seems these days that everyone has a cellular phone. Whether yours is for business purposes or personal use, you need an efficient way of charging the battery in the phone. But, like most people, you probably don t like being tethered to the wall. Imagine a system where your cellular phone battery is always charged. No more worrying about forgetting to charge the battery. Sound Impossible?
It is the focus of this thesis to discuss the first step toward re ....etc
