Teaching Methods
THE COURSE INCLUDES THEORETICAL LESSONS, CLASSROOM EXERCISES AND LABORATORY ACTIVITIES.

IN THE CLASSROOM EXERCISES THE STUDENTS ARE ENGAGED IN COMPUTATIONS RELEVANT TO A POWER SUPPLY DESIGN TO BE DEVELOPED DURING THE COURSE.

THE LABORATORY ACTIVITIES ARE PERFORMED BY MEANS OF THE TEXAS INSTRUMENTS PMLK EDUCATIONAL BOARDS TO DO THE STATIC AND DYNAMIC EXPERIMENTAL ANALYSIS OF DC-DC REGULATORS.

THE TEACHING IS "IN PRESENCE" AND THE LANGUAGE OF INSTRUCTION IS ITALIAN.
Verification of learning
THE GOAL OF THE EXAM IS TO ASSESS THE STUDENT'S GLOBAL KNOWLEDGE AND UNDERSTANDING OF CONCEPTS DISCUSSED IN THE COURSE, THE ABILITY TO APPLY SUCH KNOWLEDGE IN THE DESIGN OF POWER SUPPLIES, THE JUDGMENT AUTONOMY, THE COMMUNICATION ABILITY AND THE LEARNING ABILITY.

THE EXAM CONSISTS OF A DESIGN REPORT AND OF AN ORAL DISCUSSION. THE DESIGN REPORT CONCERNS DESIGN ISSUES RELEVANT TO A POWER SUPPLY - SUCH AS THE SELECTION AND DESIGN OF POWER STAGE AND CONTROLLER SUITABLE FOR THE ACHIEVEMENT OF STATIC AND DYNAMIC PERFORMANCES REQUIRED BY THE APPLICATION - AND INCLUDES THE DESCRIPTION OF THE DESIGN GOALS, THE APPROACH ADOPTED, THE RESULTS ACHIEVED AND THEIR CRITICAL DISCUSSION. THE DESIGN REPORT IS EVALUATED BASED ON THE CORRECTNESS OF THE DESIGN APPROACH AND QUALITY OF RESULTS ACHIEVED. THE GOAL OF THE ORAL DISCUSSION IS TO ASSESS THE STUDENT'S ABILITY TO PRESENT AND DISCUSS THE REPORT CONTENTS, THE DESIGN CHOICES, AND THE OVERALL KNOWLEDGE OF THE TOPICS OF THE COURSE.

IN THE FINAL GRADE OF THE EXAM, EXPRESSED IN THE NUMERIC SCALE FROM 18 (WORST) TO 30 (BEST), THE REPORT EVALUATION AND THE ORAL DISCUSSION ARE EQUALLY WEIGHTED.

THE MINIMUM REQUIREMENT TO PASS THE EXAM IS TO SHOW THE CAPABILITY OF DESCRIBING IN A CLEAR AND CORRECT WAY THE CHARACTERISTICS OF POWER SEMICONDUCTOR AND PASSIVE DEVICES, THE VOLTAGE-MODE AND CURRENT-MODE CONTROL TECHNIQUES, AND THE BASIC DESIGN CRITERIA OF THE POWER STAGE AND CONTROLLER OF A DC-DC BUCK REGULATOR.

THE REQUIREMENT FOR THE ACHIEVEMENT OF THE HONORS IS TO SHOW THE CAPABILITY OF USING WITH MASTERY THE CONCEPTS, THE MODELS AND THE METHODS TREATED IN THE COURSE TO PERFORM A COMPARATIVE ASSESSMENT OF DIFFERENT DESIGN SOLUTIONS SUITABLE TO COMPLY WITH GIVEN EFFICIENCY AND ACCURACY SPECIFICATIONS OF A DC-DC BUCK REGULATOR.
