ABSTRACT

Power quality is essential for smooth functioning of industrial process. As industries expand, utilities become more interconnected and usage of electrically equipment increases, power quality is jeopardized. The quality of power in the power system is severely affected by the presence of harmonics. This harmonics adversely effects the power system performance. Some of the effects are over heating of metal parts, noise in motors, low efficiency in motors etc. The effects produced by the harmonics are reduced by a ....etc

Abstract
This paper describes the conception and analysis of a unidirectional hybrid three-phase rectifier suitable for mediumand high-power applications. The rectifier is composed of a single-switch diode bridge boost-type rectifier in parallel with a pulsewidth modulation (PWM) three-phase unidirectional boost rectifier. The objective is to obtain a structure capable of providing sinusoidal input currents with low harmonic distortion and dc output voltage regulation. The diode rectifier operates at low frequency and has a higher outpu ....etc

The Vienna Rectifier is a pulse-width modulation rectifier, invented in 1993 by Johann W. Kolar. It provides:

Three-phase three-level three-switch PWM rectifier with controlled output voltage.
Three-wire input, no connection to neutral.
Ohmic mains behaviour
Boost system (continuous input current).
Unidirectional power flow.
High power density.
Low conducted common-mode EMI emissions.
Simple control to stabilize the neutral point potential.
Low complexity, low realization effort

THREE PHASE DUAL CONVERTER
Introduction
Thyristor based three-phase controlled rectifiers are widely used in the industry for controlling dc motor drives. Controlled rectifiers offering power conversion from ac to dc are reliable and have higher lifetime compared to other converters. DC motors have higher torque than ac motors and hence are suitable for variable speed and speed reversing applications requiring high torques. Although the operation of controlled rectifiers is simple, the realization of the converter control circuit is complex i ....etc

ABSTRACT
Almost all firms use UPS systems. They maintain the continuity of supply in case of power outages. But all UPS equipments regardless of manufacturer should be completely de-energized for preventive maintenance at least once per year. This limits the availability of the power system.
But now-a days certain configurations of the UPS systems are there to permit concurrent maintenance so that we can overcome the above problem.
