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

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

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

A New Control Scheme for a Class-D Inverter with Induction Heating Jar Application by Constant Switching Frequency
ABSTRACT
In this paper, a simple power control scheme for a constant frequency Class-D inverter with a variable duty cycle isproposed. It is more suitable and acceptable for high- frequency induction heating (IH) jar applications. The proposedcontrol scheme has the advantages of not only wide power regulation range but also ease of control output power. Also itcan achieve a stable and efficient Zero-Voltage-Switching (ZVS ....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
