mini projet report
Voltage source inverters (VSI) have been widely used in uninterruptible power supplies, unified power flow controllers or unified power quality conditioners, and distributed generation systems (DGS). VSIs are inherently efficient, compact, and economical devices used to control power flow and provide quality supply. VSIs can be classified as voltage-controlled VSIs (VCVSIs) and current-controlled VSIs (CCVSIs), depending on their control mechanism. In this paper, a detailed comparison of VCVSIs and CCVSIs for DG ....etc

Abstract

In adjustable speed drive applications, the switching of the inverter semiconductors generates common
mode currents as well as harmful overvoltages on the motor terminals when long cables are used.
Consequently, bulky and expensive input and output filters must be used. This work aims at reducing
these disturbances from their origin by using a three-level neutral-point-clamped (NPC) inverter
controlled with a new pulse-width-modulation (PWM) strategy. Whereas previous common mode
noise-reducing strate ....etc

Introduction

Current-fed inverters requires a stiff constant current source input - thus are sometimes referred to as CSI (current source inverters or current stiff inverters).

A large inductance can be used to change a variable voltage input to a variable current input.

VSI-inverters and CSI-inverters are dual to each other.
Introduction (cont d)
Power semiconductor devices used in CSI inverters must be able to withstand large reverse voltages. Therefore, power MOSFETs, BJ ....etc

Abstract
A general pulsewidth modulation (PWM) method for control of four-switch three-phase inverters is presented. The proposed vector PWM offers a simple method to select three or four vectors that effectively synthesize the desired output voltage, even in presence of voltage oscillations across the two dc-link capacitors. The method utilizes the so called space vector modulation, and includes its scalar version. Different vector combinations are compared. The effect ofWye and delta motor winding connections over the pulse width modu ....etc

Pulse Based Dead Time Compensator for PWM Voltage Inverters



I. Introduction
The state of the art in motor control provides an adjustable
voltage and frequency to the terminals of the motor
through a pulse width modulated (PWM) voltage source inverter
drive. As the power devices change switching states,
a dead time exists. Although the dead time is short, it
causes deviations from the desired fundamental output voltage.
While each deviation does not appreciably affect the
fundamental voltage, the ac ....etc
