INCORPORATING WIRELESS POWER TRANSFER IN AN LED LIGHTING APPLICATION


INTRODUCTION

THE BEGINNING OF WPT
Electricity by today’s standards is considered an essential to life. Electricity has been the fuel for technological development since its first applications dating back to the late 16th century. This marvelous phenomenon, however, comes with a price. The cost of maki ....etc

Abstract –
This study examines the feasibility of a multi-kilowatt wireless radio frequency (RF)
power system to transfer power between lunar base facilities. Initial analyses, show that wireless
power transfer (WPT) systems can be more efficient and less expensive than traditional wired
approaches for certain lunar and terrestrial applications. The study includes evaluations of the
fundamental limitations of lunar WPT systems, the interrelationships of possible operational
parameters, and a baseline design approach for a notio ....etc

Experimental Results with two Wireless Power Transfer Systems


I. INTRODUCTION
This paper describes two systems that make use of RFbased
wireless power transfer. The first, WISP (Wireless
Identification and Sensing Platform), is powered
deliberately by a commercial off the shelf UHF RFID
reader that transmits 4W EIRP. The second system
harvests ambient VHF or UHF energy from TV towers.
We describe an experiment in which we powered a
commercially avai ....etc

Jet impingement heat transfer – Part I: Mean and root-mean-square heat transfer and velocity distributions
Abstract
Impinging jets provide a means of achieving high heat transfer coefficients both locally and on an area averaged basis. The currentwork forms the first stage of a two part investigation of heat transfer distributions from a heated flat surface subject to an impinging airjet for Reynolds numbers from 10,000 to 30,000 and non-dimensional surface to jet exit spacing, H/D, from 0.5 to 8. In the present paper,the rel ....etc

Wireless Power Transfer via Strongly Coupled Magnetic Resonances



introduction
In the early 20th century, before the electricalwire
grid, Nikola Tesla (1) devoted much
effort toward schemes to transport power wirelessly.
However, typical embodiments (e.g., Tesla
coils) involved undesirably large electric fields.
The past decade has witnessed a surge in the use
of autonomous electronic devices (laptops, cell
phones, robots, PDAs, etc.). As a consequenc ....etc
