A New Simplified Space Vector PWM Method for Three-Level Inverters


I. INTRODUCTION
RECENTLY, with the dramatic improvements in high
voltage technologies, high voltage insulated gate bipolar
transistor (HVIGBT) and gate commutated thyristor (GCT) are
expanding the area of their application. For the high performance
ac drive systems at increased power level, high quality
inverter output with low harmonic loss and torque pulsation
is necessary. In case of the conventional two-level inverter
con ....etc

Abstract

This paper presents simplified space vector pulse width modulation (SVPWM) based vector controlled induction motor drive. The conventional SVPWM algorithm constructs the required voltage vector in the average sense by using active and zero voltage vectors. Moreover, complexity involved in conventional SVPWM algorithm is more. Whereas, the proposed SVPWM algorithm calculates the switching times using the concept of imaginary sw ....etc

1.Introduction:
The first railways in India were built in 1853 and their subsequent continent-wide development saw the appearance of various private railway companies and state-owned railway systems. To enforce standardization and coordination between these sometimes-disparate systems, the Central Standard Office (CSO) was established in 1930 to prepare designs, standards and specifications.
However, before Indian independence in 1947, most of the design and manufacturing of rolling stock and infrastructure was entrusted to foreign c ....etc

SEMIANR REPORT ON MapReduce: Simplified Data Processing On Large Clusters

Abstract
In the new era of computing, instead of buying software for satisfying the computing needs of users, millions are rely on the Internet. Internet services are already significant forces in searching, retail purchases music downloads and auctions. But the web data sets are large and the computations have to be distributed across hundreds or thousands of machines inorder to finish in a reasonable amount of time ....etc
