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

?CAN MACHINES THINK?
Neural network is a massively parallel distributed processor made of simple processing units which has a natural propensity for storing experimental knowledge and making it available for us. Neural network are a different paradigm for computing. v Von Neumann machines are based on the processing / memory abstraction of human information processing. v Neural networks are based on the parallel architecture of human brain. For the insulation design of high voltage apparatus, electric field optimization technique becomes indis ....etc

ABSTRACT

A new operational mode for diode-clamped multilevel inverters termed quasi two-level operation is proposed. Such operation aims to avoid the imbalance problem of the dc-link capacitors for multilevel inverters with more than three levels and reduces the dc-link capacitance without introducing any significant voltage ripple at the dc-link nodes. The proposed operation can be generalized for any number of levels. The validity of the proposed multilevel inverter operational mo ....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
