Implementation of Full-Bridge Current-Fed Resonant Boost Converter using PIC microcontroller
ABSTRACT
This paper presents a current-fed full-bridge boost DC-ACDCconverter with transformer isolation operating withoutswitching power dissipation. The output voltage is regulatedby dc-ac converter whose frequency changes with a constantturn-off time of transistors. The proposed converter is devoidof parasitic oscillations, as all of the parasitic capacitancesand inductances are included in a resonant tank circuit. Themain advantage of such ....etc

Kim Kardashian has revealed that she intended to start trying for babies just four weeks before she decided to split from her NBA husband Kris Humphries. The pair brought an end to their marriage after just 72 days, and it has been one of the biggest talking point in recent times. Many have been criticising Kim Kardashian by saying that the whole marriage was a setup. However, the TV reality star has revealed that she badly wanted to have some babies, and that they were about to try for the same just weeks before splitting.
One of the main re ....etc

Introduction
Tokyo Japan, February 19, 2002: Nine leading companies today announced that they have jointly established the basic specifications for a next generation large capacity optical disc video recording format called Blu-ray Disc. The Blu-ray Disc enables the recording, rewriting and play back of up to 27 gigabytes (GB) of data on a single sided single layer 12cm CD/DVD size disc using a 405nm blue-violet laser.
By employing a short wavelength blue violet laser, the Blu-ray Disc successfully minimizes its bea ....etc

Current-Fed Resonant Full-Bridge Boost DC/AC/DC Converter
INDIRECT dc/ac/dc converters utilizing an isolation transformer
are widely used in different applications, such as
battery chargers and dischargers, uninterruptible power systems,
alternative energy systems, hybrid electric vehicles, and
medical X-ray imaging.
In the case of the applications where low input voltages have
to be converted to high output voltages, current-fed converters
are used, whereas in the case of higher power applications, fullbridge
boost conv ....etc

ABSTRACT
Due to efficient control methods, DC motors are widely used motors to drive the loads in industry. Among the different control techniques for the DC motor speed control, armature voltage control method using Pulse Width Modulation (PWM) technique is the best one. We can realize the PWM control method u ....etc

Paolo CLEMENTE1, Mehmet ÇELEBI2, Giovanni BONGIOVANNI1, Dario RINALDIS1

INTRODUCTION
Identification of dynamic characteristics of structural systems is an important step that is necessary for two basic reasons: − to assess possible dynamic behavior of structures during strong events and − to gain experience on the general dynamic characteristics of structural systems such that the experience and data base can be used in future design and analyses. Past efforts ....etc

SYNOPSIS

Non- destructive estimation of particle size of finished products is essentially required to judge their suitability for intended applications. For this estimation, a ceramic heating element (SiC rod) of a heat Treatment furnace at 1400 Degree celcius has been chosen. The particle size has been estimated with the proposed method based on counting reflection spots in a back reflection X-Ray pattern. Calibration curve has been drawn on the basis of the data obtained by standard sieve me ....etc
