ANALYSIS on DIGITAL ELECTRONIC DISPLAY SYSTEM. People are using most effectively Digital Electronic Display Systems for highlighting their product innovations in markets, trade shows, exhibitions, seminars etc and now-a-days it is being randomly used in a large Bill boards to show down the world class ceremonies like Olympic game, World cup Cricket, World cup football in the different venues of the world. Display systems use a wide range of modalities categorized mainly into direct view & projection system.These devices can also be classified as Light-Emitting and Non-Light-Emitting...

A new topology has emerged out of the research to provide four quadrant operation of a high frequency dc-dc converter having one supply source and easy gate pulse control. This new topology has been developed out of switching dc-dc converters with voltage lift circuits; its operational range is wide at high conversion efficiency, whereas, the present four quadrant switching dc-dc converters conversion efficiency decreases around the operation of a particular duty cycle. The result is a single source topology switched by conventional ON/OFF duty cycle control as used in other high power...
