This course provides the student with an in depth knowledge about the themes of systems and circuits used for powering electronic circuits and small electromechanical actuators. Students will study mainly DC-DC converters, analyzing energy efficiency, control, isolation and electromagnetic noise generation which shouldn’t inject disturbances in the mains. This class has a strong design flavor: most important methods of analysis and design both for power and control stages will be presented.

This class has a strong design flavor: most important methods of analysis and design both for power and control stages will be presented.

After this course, a student will have a detailed knowledge of the basic DC-DC power conversion topologies, in particular buck, boost, buck boost, their working modes. He or she will know some methods for deriving a linear small signal model of switching converters. Beside the non-isolated topologies, a student will learn the detailed behavior of the most common derived converters using an isolation transformers, including their small signal models.
By the end of this course, a student will be able to design both the power and control section of an isolated converter, choosing the best among various different topologies and control methods, and estimating the component stress and total circuit efficiency.

Written test with a theory section (closed books, 30min) and a design problem section (open books 2hrs). A few days after the written part there is a 45 minutes oral exam. Each written section and the oral exam is about one third of the final grade. First written section tests the basic knowledge of the DC to DC converters. The second section tests the student design capability, requiring a full converter design according to given specifications. Design must include topology choice, power stage design, determination of its small signal model and compensator design. Oral part starts discussing the written test and evolves towards more specific and in depth subjects, mainly theoretical.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.

Written test with a theory section (closed books, 60min) and a design problem section (open books 1.5h). First written section tests the basic knowledge of the DC to DC converters. The second section tests the student design capability, requiring a full converter design according to given specifications. Design must include topology choice, power stage design, determination of its small signal model and compensator design.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
