This book presents the reader, whether an electrical engineering student in power electronics or a design engineer, a selection of power converter control problems and their basic digital solutions, based on the most widespread digital control techniques. The presentation is primarily focused on different applications of the same power converter topology, the half-bridge voltage source inverter, considered both in its single- and three-phase implementation. This is chosen as the test case because, besides being simple and well known, it allows the discussion of a significant spectrum of the most frequently encountered digital control applications in power electronics, from digital pulse width modulation (DPWM) and space vector modulation (SVM), to inverter output current and voltage control, ending with the relatively more complex VSI applications related to the so called smart-grid scenario. This book aims to serve two purposes: (1) to give a basic, introductory knowledge of the digital control techniques applied to power converters; and (2) to raise the interest for discrete time control theory, stimulating new developments in its application to switching power converters.

Simone Buso graduated with a degree in electronic engineering from the University of Padova in 1992. He received his Ph.D. degree in industrial electronics from the same university in 1997. Since 1993, he has been with the power electronics research group of the University of Padova. He is currently a member of the staff of the Department of Information Engineering (DEI) of the University of Padova, where he holds the position of Associate Professor of electronics. His main research interests are in the industrial and power electronics fields and are specifically related to converter topologies, digital control control of power converters, solid-state lighting, and renewable energy sources. Simone Buso is a member of the IEEE. Paolo Mattavelli received his Ph.D. degree in electrical engineering from the University of Padova, Padova, Italy, in 1995. From 1995-2001, he was a Researcher at the University of Padova. From 2001-2005, he was an Associate Professor the University of Udine, where he led the Power Electronics Laboratory. In 2005, he joined the University of Padova, in Vicenza, with the same duties. From 2010-2012, he was a Professor and Member of the Center for Power Electronics Systems (CPES) at Virginia Tech. He is currently a Professor at the University of Padova. His major research interest includes analysis, modeling and analog and digital control of power converters, grid-connected converters for renewable energy systems and micro-grids, and high-temperature and high-power density power electronics. In these research fields, he has been leading several industrial and government projects. Paolo Mattavelli is a Fellow of the IEEE.
