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

mini projet report
Voltage source inverters (VSI) have been widely used in uninterruptible power supplies, unified power flow controllers or unified power quality conditioners, and distributed generation systems (DGS). VSIs are inherently efficient, compact, and economical devices used to control power flow and provide quality supply. VSIs can be classified as voltage-controlled VSIs (VCVSIs) and current-controlled VSIs (CCVSIs), depending on their control mechanism. In this paper, a detailed comparison of VCVSIs and CCVSIs for DG ....etc

Abstract—
In this paper, the method of triangular carrier
switching control of two-level inverters is extended to cascaded
multilevel inverters using phase-shifted multicarrier unipolar
pulsewidth modulation (PWM). The condition for smooth modulation
is obtained using the Bessel’s function representation of
the PWM output and the switching condition of the multilevelinverter-
controlled system. A method is proposed for the determination
of the minimum amplitude of the triangular carrier
for smooth modulation at fixed switch ....etc

Abstract

Inverter-based distributed generation has large potential to provide premium power quality.An adaptive grid-voltage sensorless interfacing scheme for inverter-based distributed generation (DG) units based on an
adaptive grid-interfacing model. First, a discrete-time model of a current controlled grid- connected inverter is presented.Then, an adaptive grid- interfacing model is designed with low computational demand to estimate, in real-time, the interfacing (impedance) parameters seen by the inverter and the grid v ....etc
