Pulse width modulation methods are widely used for§the synthesis of ac voltages at the terminals of a§voltage-sourced converter (VSC). Traditionally§sinusoidal pulse width modulation (SPWM) has been§used. A powerful alternative is space vector§modulation (SVM), in which the converter is placed in§a finite number of states in order to best§approximate the reference voltage.§§§The primary objective of this book is to provide a§solid framework for advanced modulation techniques§for high power applications. This book reviews the§pulse width modulation techniques, studies the SVM§method for two- and three-level VSCs, and features an§extensive bibliography. It also develops simulation§models for a number of modulation strategies, studies§and compares the losses§associated with modulation, presents a number of case§studies, and employs genetic algorithms to find an§optimized SVM sequence for improved harmonic §performance.§§§This book is intended for use by graduate students in§power electronics and power systems and both new and§experienced engineers as a comprehensive reference§for modulation strategies.
