Schottky diode

ABSTRACT This paper deals with a Cuk Topology for Power Factor Correction (PFC). Most of the front-end PFC converters are designed using diode bridge and has lower efficiency due to losses with reduced power factor.The current flow, during each intervals of the switching cycle reduces the conduction losses compared to the conventional Cuk PFC Rectifier. The converter also provides protection against inrush current occurring at start-up, decreases input current ripple and reduces Electromagnetic

lightwave systems: The optical emitted by the light source remains confined. Unguided: The optical beam emitted spreads out in space. A.Transmitters: The most commonly used optical transmitters are semiconductor devices such as light-emitting diodes (LEDs) and laser diodes. The difference

maybe on that. Well whatever you are reading this on prepare to empty you’re wallet’s because this new technology will surly brighten your day! LED’s or Light Emitting Diodes have been around since the 60’s and I think they are starting to decline. The new technology slowly replacing LED’s are OLED’s or Organic Light Emitting Diodes. Now these are special because they contain small quantities of organic material such as carbon. OLED’s feature many vase improvements over its older friend LED’s, these

Without the help of quantum mechanics, life would be almost unrecognizable when compared to what it looks like it does today. It is incorporated into nearly every aspect of modern life, many of which are taken for granted. The entertainment industry is no different. Everything from TVs and DVD and Blu-ray players to video game consoles and even some types of stage lights would not be made possible without the use of quantum mechanics. Without the discovery of quantum mechanics, the entertainment

Setup 1 Lenovo S20 All-in-One PC Contains an Intel Pentium quad core processor, along with 4GBs of RAM along with this there is a 500GB of storage that means it has enough memory to store the files and storage that’s needed, it has a windows 8.1 operating system however this can be upgraded to windows 10 due to it being free for 2015, a keyboard and mouse is not needed as it comes with it.

(OI) for the City of Thorold in response to their Request for Proposal (RFP) for the replacement of High-Pressure Sodium Vapour Lamps (HPSV) street lights on Main and Ferry Street. The following material will describe the benefits of Light-Emitting Diode (LED) lighting compared to the current HPSV lighting used by many municipalities. Also this report evaluates the benefits LED lighting technology can provide for the City of Thorold as a possible energy efficient light source. The City of Thorold

ANEXO: DATOS EXTRACTADOS MEMORIA ANUAL IKEA A better everyday life for the many people Mikael Ohlsson, President and Chief Executive Officer for the IKEA Group Welcome to the 2011 IKEA Yearly Summary. In times when many nations and people face economic challenges, our vision of creating a better everyday for the many people is more relevant than ever. We are constantly engaged in learning about the different ways people experience life at home and what their needs are. And we know people are becoming

Throughout the world there are a large range of fruit and vegetables being produced and supplied to consumers, these products have to meet harvesting standards to ensure good quality. Cucumber (Cucumis sativus) is part of the cucurbitaceae family, is also a short day plant and originated from India. In 2012 the world produced 65,134.08 million kilos, this was a new all time high. China produces 48,000 million kilos, this is 73% of the worlds production (Fresh Plaza, 2014). Cucumbers are generally

Nick Holonyak and the Invention of Light Emitting Diode (LED) Introduction Nick Holonyak was born in the United States of America in Zeigler, Illinois on the third of November in 1928. He was the son of the immigrants from the country, which is currently called Ukraine. Holonyak studied electrical engineering at the University of Illinois at Urbana-Champaign, where he attained his Master’s along with his Ph.D. degrees and graduated in 1954 (Holonyak, 1962). He worked at the Bell Telephone Laboratories

Arduino Uno R3 is a microcontroller board. It has 14 digital input/output pins. 6 analogue inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It is much more user friendly to use. When using an Arduino it simplifies a large amount of work that needs to be done in order to get a running system.The Arduino hardware platform already has the power and reset circuitry setup as well as the circuitry to program and communicate with the micro over USB. The
