A Neural-Network-Based Space-Vector
PWM Controller for Voltage-Fed
Inverter Induction Motor Drive




abstract

neural-network-based implementation of
space-vector modulation (SVM) of a voltage-fed inverter has been
proposed in this paper that fully covers the undermodulation and
overmodulation regions linearly extending operation smoothly
up to square wave. A neural network has the advantage of very
fast implementation of an SVM algorithm that can increase the
converter switching frequency, pa ....etc

Experimental Comparison of Carrier and Space Vector PWM Control Methods for Three-Phase NPC Converters
Abstract.
Multilevel converters are powerful converters inthe medium-voltage high-power range. Inside this family ofconverters, the three-level neutral point clamped converter hasits own importance. The main control methods associated withthis converter are the carrier-based PWM with added DCcomponents and the space vector PWM. Two of the mostimportant features of the NPC converter are the neutral pointbalance and the output voltage ....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

A New Simplified Space–Vector PWM Method for Three-Level Inverters


I. INTRODUCTION
RECENTLY, with the dramatic improvements in high
voltage technologies, high voltage insulated gate bipolar
transistor (HVIGBT) and gate commutated thyristor (GCT) are
expanding the area of their application. For the high performance
ac drive systems at increased power level, high quality
inverter output with low harmonic loss and torque pulsation
is necessary. In case of the conventional ....etc

Efficient Hybrid Carrier Based Space Vector Modulation for a Cascaded Multilevel Inverter


INTRODUCTION
Multilevel inverters have become a popular choice in recent
years, because improving the output waveform of an inverter
reduces its respective harmonic content and, hence, the size
of the filter used and the level of electromagnetic interference
(EMI) generated by the switching operations . Various
multilevel converters structures are reported in the ....etc

Abstract
This paper proposes a generalized method for thegeneration of space vector pulsewidth modulation (SVPWM) signalsfor multilevel inverters. In the proposed method, the actualsector containing the tip of the reference space vector need notbe identified. A method is presented to identify the center of asubhexagon containing the reference space vector. Using the centerof the subhexagon, the reference space vector is mapped to theinnermost subhexagon, and the switching sequence correspondingto a two-level inverter is determined. A n ....etc
