Modulation in Power Electronic Converters

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.
