Scheda insegnamento

Anno Accademico 2018/2019

Conoscenze e abilità da conseguire

At the end of the course students own the knowledge of the principles of modern power electronics: power diodes, controlled switches. They also acquire the knowledge of the following items: commutation transients, reverse recovery, and losses; how the pulsewidth modulation works, including harmonic analysis of voltage and currents. The students are further capable of calculating and improving the conversion efficiency. Knowledge of DC/DC converters, voltage and current transfer ratio, multi-level converters; DC/AC converters, single-phase, three-phase and multi-phase; The space vector analysis of multiphase AC systems; Space vector modulation of three phase inverters are also elements of the cultural skill that the students acquire at the end of the course.
