Novel Direct Torque Control Based on Space Vector Modulation With Adaptive Stator Flux Observer for Induction Motors



INTRODUCTION

Direct torque control based on space vector modulation (DTC-SVM) preserve DTC transient merits, furthermore, produce better quality steady-state performance

In a wide speed range, at each cycle period, SVM technique is used to obtain the reference voltage space vector to exactly compensate the
flux and torque errors.

SVM-DTC technique based o ....etc

In the present work the authors propose a solar powered cascaded multilevel inverter which can be integrated with the grid. To connect the solar photovoltaic system to the grid a dc to ac conversion of power is required which is made possible using a multilevel inverter, but the power electronic switches introduces harmonics during the switching process. Thus the investigators propose a selective harmonic elimination technique using Genetic Algorithm and Differential Evolution Optimization Techniques. The performance comparisons of the proposed ....etc

ABSTRACT
This paper focused on the development of capacitor voltage
balancing methods in a flying capacitor multilevel inverter
(FCMLI) fed induction motor drive. For improving the
performance of flying capacitor multilevel inverter, a switching
pattern selection scheme is implemented. The proposed method
has been designed a seven-level flying capacitor multilevel
inverter by using sinusoidal pulse width modulation technique.
The selected pattern has been exposed to give superior
performance in load voltage, total harmonics dist ....etc
