Opis

Pulse width modulation methods are widely used forthe synthesis of ac voltages at the terminals of avoltage-sourced converter (VSC). Traditionallysinusoidal pulse width modulation (SPWM) has beenused. A powerful alternative is space vectormodulation (SVM), in which the converter is placed ina finite number of states in order to bestapproximate the reference voltage.The primary objective of this book is to provide asolid framework for advanced modulation techniquesfor high power applications. This book reviews thepulse width modulation techniques, studies the SVMmethod for two- and three-level VSCs, and features anextensive bibliography. It also develops simulationmodels for a number of modulation strategies, studiesand compares the lossesassociated with modulation, presents a number of casestudies, and employs genetic algorithms to find anoptimized SVM sequence for improved harmonic performance.This book is intended for use by graduate students inpower electronics and power systems and both new andexperienced engineers as a comprehensive referencefor modulation strategies.
