Learning Objectives
The course covers the main equipments used for controlled static conversion of electrical energy and their
most important applications. Of each scheme the operating characteristics and the design criteria are
examined. The aim is to provide students with the tools to understand the working principle and design
criteria of the most used power converters, depending also on their specific application.
Prerequisites
Calculus. Geometry. Electrotechnics.
Teaching Methods
Lectures supported by ìprojector, laboratory team-works, personalized feedback and coaching to improve every aspect of the student's work.
Further information
A successful student should know, understand and evaluate the operation and the design criteria of the main
power electronic converters.
Type of Assessment
Intermediate tests just for students attending the course; Oral exam
