Investigating Efficiency of AC Direct Drive of LED Lighting

This project explores the rapidly-expanding area of AC direct drive for LED lighting. AC LED driving does not use typical DC-DC converter-based driving but uses semiconductor switches and a linear regulator to activate a number of LEDs proportional to the input voltage at any given time. This allows bulky, expensive magnetics to be eliminated from the system. The goal of this project was to develop a flexible simulation of a common AC LED system to find areas of significant power loss and attempt to improve them. This allows future versions of an AC LED system to start with major loss areas in mind, reducing development time and increasing performance. Systems tested included a three-stack binary switching system, a four-stack step-up switching system, a four-stack binary switching system, and a five-stack binary switching system. Through each simulation, the common theme was that the loss of the linear regulator was the dominant loss of the system. It was found that as the number of switches (and therefore switch states) increased, the loss of the MOSFET could be reduced significantly by reducing the voltage dropped across it. With three stacks using binary switching, MOSFET loss was 22.4W, or 29% of input power. With five switches, the MOSFET loss was reduced to 333mW, or less than 1% of input power

How a Plane Crash Changed My Life

In 1983 Ted Leonsis survived a crash landing of a plane he was on.This fateful event proved to be a pivotal point in his life. One of the byproducts of that near-death experiences is Leonsis’ list of 101 things to do before he died—a bucket list” before the movie of that title came out. Leonsis has managed to accomplish more than two-thirds of the things on his list including owning a sports franchise (the Washington Capitals), changing someone’s life via a charity, sailing the Caribbean, and being on the cover of a magazine. As impressive as these accomplishments are, they do not reveal the person underneath these accomplishments or what has driven this serial entrepreneur. In previous interviews appearing in NEJE, we have explored how a person’s faith tradition impacts how they run and manage their businesses. In this interview Leonsis reveals how his life was shaped by both his early childhood and the transformational experience of a crash landing. This interview examines not only what drove Leonsis to success, but also why he feels failure is important. Along, the way he offers his perspective on corporate social responsibility and why it is so critical for individuals and companies to give back to society. And finally, Leonsis shares what he has learned about the secret to happiness
