Digital Control in Power Electronics
The lecture will address several latest issues related to the modeling, design, implementation of digital control in Power Electronics, with a specific focus on high-frequency switching converters. The lecture will first describe some basics related to the modeling and implementation of digitally controlled power converters. The effect of oversampling on the reduction of the control delay and on the achievable dynamic response is discussed. Then some digital control design criteria, starting from the standard equivalent analog representation and then moving to the discrete time analysis with some illustrative design compensation examples. The lecture will then move to non-linear action (such as the time-optimal approach) to highlight the benefits of the digital approach. To complete the overview of some high-performance digital control, the digital hysteresis modulation, the time-event control and the oversampled control are presented. Finally, a set of auto-tuning techniques will be addressed. The final part of the lecture will address some examples of grid-connected power converters, to show how some of the proposed analysis can be applied also to power converters connected to the utility grid.

Digital Control in Power Electronics
Paolo Mattavelli received the Ph. D. degree in electrical engineering from the University of Padova (Italy) in 1995. Since 1995 he has had faculty positions at the Universities of Padova (Italy), Udine (Italy) and at Virginia Tech (USA). He is currently a professor with the University of Padova. His major field of interest includes analysis, modeling and analog and digital control of high-temperature and high-power density power electronics. In these research fields, he has been leading several industrial and government projects. He has published about 140 journal papers, 330 conference papers, and 12 patents. His current google h-index is 75. He is an IEEE Fellow and Co-Editor in Chief for the Transactions on Power Electronics.
