Improvement of Power Quality Using PWM Rectifiers

The paper presents the modeling, simulation and analysis of an AC-DC converter based PWM rectifier. It provides a suitable control algorithm for a pulse width modulation rectifier which reduces ripple from the DC output side as well as shapes the input current properly. The basic objective of a PWM rectifier is to regulate the DC output voltage and also ensure a sinusoidal input current and unity power factor operation. This is implemented by high speed IGBT switches connected in anti parallel mode across the rectifier diodes

Coordinated Control of DFIG under Grid Fault  Condition in Wind Energy Conversion System

This paper proposes a coordinated control of rotor side converters (RSCs) and grid side converters (GSCs) of variable speed doubly-fed induction generator (DFIG) based wind generation systems under unbalanced voltage conditions. The control scheme uses stator flux-oriented control for the rotor side converter and grid voltage vector control for the grid side converter. System behaviours and operations of the RSC and GSC under unbalanced voltage are illustrated. The cocoordinated control schemes manage to restore the wind turbines normal operation after the clearance of fault

A Miniaturized Ultra Wideband (UWB) Antenna Design  for Wireless Communications

This paper presents a miniaturized planar circular disc UWB antenna design for wireless communications. Printed on a dielectric substrate and fed by 50Ω microstrip line with truncated ground plane, the proposed antenna has been demonstrated to provide an ultra wide 10dB return loss bandwidth with satisfactory radiation properties. The special structure reduces the spatial volume and it is used to realize the miniaturization of the antenna. Ansoft High Frequency structure Simulator (HFSS) software tool has been employed for obtaining the simulation results. The return loss, voltage standing wave ratio (VSWR), radiation patterns and current distributions of the antenna are discussed.

Dopuzao je do nogu cara Putina, kao zadnji crv i sada se uvija, cvileći i moleći besramno za još malo vremena oko brodova

Oland je sasvim slučajno navratio. Neće dalje od aerodroma, jer, eto, stvarno žuri. A već kad je tu, zaista potpuno slučajno, prozboriće par reči sa Putinom. Nije nego. Dopuzao je do nogu cara Putina, kao zadnji crv i sada se uvija, cvileći i moleći besramno za još malo vremena oko brodova.

Bojim se, da istoriju Evrope i sveta ucimo, kao hronologiju ratova i spoljnih vidljivih dogadjaja i promena

Tako je stvorena osnova "Atlanske imperije", formalno nepostojece (a, zato, pored ostalog, mocne). Istovremeno sa procesom ove imperije, odvija se i proces povezivanja Rusije I nemackih drzava (pocev od ruskog cara, Petra Velikog). Kako bi se sprecila ta "preopasna" veza, na Rusiju je gurana Turska, Japan, Francuska (Napoleon), ... Ujedinjenjem Nemacke, pod Bizmarkom, doslo je do jos vece pretnje interesima "imperije". Ni politicka eliminacija Bizmarka, nije sprecila logican proces privrednih i trgovackih veza Nemacke i Rusije.

Design of 800 MHz to 1.5 GHz Voltage Controlled  Oscillator for Data Communication

High frequency variable oscillator is central to the construction of high speed clock for data communication. A very wide variable frequency oscillation is designed that could be used in data communication for reliable and fast data transmission. A voltage controlled oscillator in Colpitt configuration is used in the design. The design is found to be capable of producing frequencies from 800MHz to 1.5GHz for a reverse biased voltage (VR) of 0 to 25V while maintaining a good tuning flatness throughout the range. The design is found to be free from noise and frequency variations over the tuning range.

Izbijanja na vrh, Franca Ferdinada (sina carevog br ata), vec visestruko nepodobnog i nezeljenog buduceg cara. On predstavlja smetnju vojnim krugovima i dvorovima

Ocenjujuci rezultate I sv. rata, kao oslobodjenje ipobedu demokratije nad autoritarizmom ("mracnim vekovima"), znaci ponistenje nauke u istorijji i prelazak u politikantstvo. Svakako, kraj rata je doneo slobodu okupiranim zemljama i narodima ali i razaranje drzavnosti, pre svih, Rusije i Nemacke (koja, do danas nije povratila svoj suverenitet). Posebno, jos tokom rata, pod Kerenskim ("slucajno",sluzbenikom MI6), pre dolaska Lenjina, Trockog, ... i komunista na vlast, toko prvih meseci 1917, u potpunosti je razgradjena drzavnost (njene institucie) Rusije, kao i nemacke i austrijske carevine(i dodatno, turske).

An Improved VCO Design with Negative Feedback to  Reduce Jitter at High Frequencies

This paper presents an improved design of voltage controlled oscillator (VCO) utilizing the three differential cell CMOS inverters for forming the ring oscillator. The differential cell reduces the power supply fluctuations impact on the oscillator jitter while the negative feedback from frequency to voltage converter reduces the jitter at high frequencies. Finally the proposed model is designed using CMOS 0.18um foundry technology and simulated using P-Spice software. The result shows that the proposed design improves the jitter attenuation at different offset frequencies up to 40dB
