The Impact of Timer Resolution in the Efficiency Optimization of Synchronous Buck Converters


My name is Pedro Amaral and I am currently writing my Master’s dissertation at the Faculty of Engineering of the University of Porto in colaboration with Infineon Technologies AG. The goal of my work is to develop an optimization algorithm for microcontroller-based DC/DC converters, which optimizes the dead time insertion on MOSFET driving. The study of the characteristics of a digital controller for the optimization of dead time will be realized too, with particular emphasis on the timer resolution. Ultimately, this leads to a power efficiency improvement, with positive consequences in terms of operation costs, powertrain longevity and environmental protection.
