An Integrated Silicon Carbide (SiC) Based Single Phase Rectifier with Power Factor Correction



I. INTRODUCTION
Power supplies are one of the most crucial building
blocks of a modern society, converting high-voltage AC
into low-voltage DC for use in electronic circuitry in office
equipment, telecommunication, and consumer electronics.
Over 2.5 billion AC/DC power supplies are currently in use
in the United States alone, about 6 to 10 billion are in use

magine if killing flu viruses and other microbes were as simple as turning on a light.

Exposing a unique surface coating to light may in fact hold the key to protecting you from virtually all viruses and bacteria, including the feared avian flu.

Laboratory testing of a novel, permanent nano-coating, developed in collaboration by researchers at North Carolina State University College of Textiles and Emory University School of Medicine, has been shown to kill or inactivate most viruses and bacteria when exposed to visible light. Early tes ....etc

A Scalable SIC Device for DC/DC Converters in Future Hybrid Electric Vehicles


2)INTRODUCTION
This work is motivated by an industry wide interest to integrate SiC power devices in future automotive applications. The need to mount electric motor drives and other power converter electronics under the hood and as close to the motor as possible demands that the power electronics installed must either be capable of enduring the high under-hood temperatures or incor ....etc

Strong Field-Effect in Graphene on SiC



Graphene, consisting of monolayer thick carbon, can be produced as an isolated layer (exfoliated graphite) or as an epitaxial layer on a SiC(0001) surface. We have used the latter method to produce graphene on 4H-SiC by heating at 1300°C in ultra-high vacuum with in-situ monitoring by electron diffraction. The graphene formation is performed at CMU, while transistor fabrication (with 1.5x0.5 mm2 channel area) is performed at Sarnoff Corp. A ....etc

ABSTRACT
In this paper an attempt has been made to increase the reliability of engine using Al-SiCp composites as an alternative material for the engine valve guides. Aluminum matrix composites are finding increased application in automotive, aircraft and aerospace industries and hold the greatest promise for the future growth. The finite element analysis of the Al-SiCp composite engine valve guide was done using Ansys software. The temperature, principal stress and principal strain distribution over the entire surfa ....etc
