Objectives of the course
This course aims to provide a fundamental treatment of the broad range of topics that characterises the multidisciplinary course content. The goal is achieved by using the powerful approaches of modern power electronics and electric machines theories, requiring minimum prerequisites. Theory concepts are applied to actual cases by means of examples, exercises and simulations
Physics; basic circuit theory; electronics, control theory and electric machines fundamentals.
