| Objectives | |
|---|---|
| THE COURSE AIMS AT LEARNING TOPICS CONCERNING NON-LINEAR CIRCUITS AND SYSTEMS, THE ELECTROMECHANICAL AND THE STATIC ENERGY CONVERSION. SOME ELEMENTS CONCERNING RENEWABLE ENERGY SYSTEMS, BATTERIES AND ELECTRICAL SAFETY ARE ALSO GIVEN. KNOWLEDGE AND UNDERSTANDING: METHODS FOR THE ANALYSIS OF THE ELECTROMECHANICAL CHARACTERISTICS OF THE MAIN DC AND AC MOTORS AND OF THE SWITCHING CONVERTERS USED FOR MOTOR DRIVING AND IN THE SYSTEMS PRODUCING ELECTRICAL POWER FROM RENEWABLE ENERGY SOURCES. APPLYING KNOWLEDGE AND UNDERSTANDING: TO BE ABLE TO ANALYZE THE ELECTROMECHANICAL CHARACTERISTICS OF DC AND AC MOTORS AND THE OPERATING PRINCIPLES OF THE MAIN CIRCUITS FOR THE STATIC ENERGY CONVERSION. |
| Prerequisites | |
|---|---|
| FOR THE SUCCESSFUL ACHIEVEMENT OF THE COURSE GOALS, A BASIC KNOWLEDGE OF CIRCUIT THEORY IS USEFUL. |

| Teaching Methods | |
|---|---|
| LECTURES (60%) AND CLASSROOM PRACTICE (40%) BASED ON THE USE OF A CIRCUIT SIMULATOR AND A COMPUTATIONAL SOFTWARE. SOME LECTURES COULD BE HELD OUTSIDE THE UNIVERSITY CAMPUS IN ELECTRIC MACHINES FACTORIES. TOTAL NUMBER OF HOURS: 60. ATTENDING LECTURES AND CLASSROOM PRACTICE IS MANDATORY. LANGUAGE: ITALIAN. |
| Verification of learning | |
|---|---|
| THE FINAL EXAM WILL EVALUATE AS A WHOLE: THE KNOWLEDGE AND UNDERSTANDING OF THE CONCEPTS PRESENTED IN THE COURSE, THE ABILITY TO APPLY THAT KNOWLEDGE TO SOLVE PROBLEMS OF ANALYSIS OF CIRCUITS AND SYSTEMS FOR THE STATIC AND THE ELECTROMECHANICAL ENERGY CONVERSION. THE EXAM CONSISTS OF AN ORAL INTERVIEW AIMED AT ASSESSING THE ACQUIRED KNOWLEDGE AND ABILITY TO UNDERSTANDING, THE ABILITY TO LEARN, AND ORAL PRESENTATION QUALITY. THE ORAL EXAMINATION WILL DEAL WITH ALL THE TOPICS OF THE COURSE AND, IF CHOSEN BY THE STUDENTS, ON THE DISCUSSIONS OF NON MANDATORY REPORTS AND INSIGHTS FACED IN GROUPS. THE ASSESSMENT WILL TAKE INTO ACCOUNT THE KNOWLEDGE DEMONSTRATED BY THE STUDENT AND THE DEGREE OF ITS DEPTH, PROVEN ABILITY TO LEARN, THE QUALITY OF THE PRESENTATION AND THE PROVEN CAPACITY OF WORKING IN GROUPS. THE FINAL EVALUATION IS EXPRESSED IN THIRTIETHS. MARKS=18 CAN BE GIVEN TO STUDENTS DEMONSTRATING VERY LIMITED BUT SUFFICIENT KNOWLEDGE AND APPLICATION SKILLS. MARKS=30 CAN BE GIVEN TO STUDENTS SHOWING A COMPLETE KNOWLEDGE OF METHODS, TECHNIQUES AND CONCEPTS PRESENTED, LINK THEM THE ONE ANOTHER, DEMONSTRATING A VERY EFFECTIVE APPROACH TO PROBLEM SOLVING AND ABLE TO FIND ACCURATE SOLUTIONS. HONORS (30 E LODE) CAN BE GIVEN TO STUDENTS DEMONSTRATING THAT THEY CAN APPLY THE ACQUIRED KNOWLEDGE WITH CONSIDERABLE AUTONOMY AND CRITICAL JUDGMENT ALSO TO CONTEXTS DIFFERENT FROM THOSE PROPOSED DURING LECTURES. |
