ABSTRACT
 The main objective of the thesis is to study the operation of six pulse inverter connected to an induction motor.
• In this thesis the induction motor is fed with a three phase six step voltages of variable frequency and magnitude are applied.
o For purposes of comparison the transient behavior of the motor operated with fixed supply voltage and no feedback control. For comparison purposes 20HP, 220-V, 60HZ, Four-pole, squirrel cage induction motor is used.

Diode Clamped Multilevel Inverter Fed Induction Motor


INTRODUCTION

Two level voltage source inverters produce an output voltage or a current with levels either 0 or ± Vdc

In high power and high voltage application these two level inverters, however, have some limitations in operating at high frequency mainly due to switching losses and constraints of device ratings.

Unique structure of ML-VSIs allow them to reach high voltages with low-harmonics wit ....etc

Field Orientated Control of a Multi-Level PWM Inverter Fed Induction Motorr
abstract
This thesis presents the simulation of a Field Orientated Control of a Multi level PWM Inverter fed induction motor system and its implementation in terms of programming and code in a real time operating system. Field Orientated Control allows precise controllability and excellent transient behaviour when used to control an induction motor by manipulating the angle and amplitude of the torque and speed producing curren ....etc

INTRODUCTION
1.1 Purpose:
This 500W Three-Phase Inverter is a project whose purpose is to support the University of Illinois Future Energy Challenge (FEC) team. The purpose of said team is to develop a motor drive system which is both highly efficient and cost effective. Successful implementation of such a design could potentially reduce national overall energy consumption by 10% annually if widely used throughout society (e.g. in household appliances and industry).1 These savings would greatly reduce CO2 releas ....etc

Introduction to Pulse Width Modulation (PWM)
In this technique several pulses are produced in each half – cycle but the width of the pulses
is not the same as in case of multiple – pulse width modulation, however the width of each pulse is
varied in accordance with the amplitude of the sine wave reference voltage. The width of the pulse
at the center of the half – cycle is maximum and decreases on either side. The figure 6(a) shows the
generation of the output signal by comparing a sinusoidal reference sign ....etc

Abstract:
This paper deals with the direct torque control of capacitor multilevel VSI actuators. The active control strategy high voltage I high power induction motors fed by floating egy for well-balancing the capacitor voltages is presented highlighting an optimal pattern. The efficiency of this approach is compared to the well-known passive method and it is illustrated by simulation. In the next section, a controlled cycle based algorithm is proposed as an attractive solution for a high performance torque control ....etc
