Objectives
THE COURSE AIMS AT ADDRESSING ISSUES RELATED TO POWER DEVICES AND POWER CIRCUITS AND DIGITAL CONTROL TECHNIQUES AND ALGORITHMS USED IN THE IMPLEMENTATION OF HIGHLY-ENERGY-EFFICIENT POWER MANAGEMENT CIRCUITS. THE AIM OF THE COURSE IS TO PROVIDE STUDENTS WITH KNOWLEDGE AND SKILLS IN DEVELOPING HIGHLY-ENERGY-EFFICIENT POWER MANAGEMENT SYSTEMS FOR ICT AND GREEN POWER APPLICATIONS.


THE MAIN KNOWLEDGE ACQUISITIONS WILL BE:
• ENERGY, POWER AND EFFICIENCY IN POWER MANAGEMENT CIRCUITS FOR POWER MANAGEMENT APPLICATIONS IN ICT AND GREEN POWER
• SEMICONDUCTOR POWER DEVICES
• STATIC AND DYNAMIC MODELS OF DC-DC CONVERTERS FOR POWER MANAGEMENT APPLICATIONS
• VOLTAGE AND CURRENT CONTROL TECHNIQUES
• ARCHITECTURE, OPERATING PRINCIPLE AND FEATURES OF A DIGITAL CONTROL SYSTEM FOR POWER MANAGEMENT APPLICATIONS;
• INFLUENCE ANALYSIS AND CRITERIA FOR SELECTING AND SETTING ELEMENTS OF A DIGITAL CONTROLLER: ANALOG-TO-DIGITAL CONVERTER RESOLUTION, CPU CLOCK FREQUENCY, SAMPLING RATE, DIGITAL PWM RESOLUTION, REFERENCE LEVEL, LOOP GAIN CROSS-OVER FREQUENCY AND PHASE MARGIN;
• PRECISION, STABILITY AND LIMIT CYCLES IN DIGITALLY CONTROLLED POWER MANAGEMENT CIRCUITS;
• C LANGUAGE ENCODING, SIMULATION IN PSIM / MATLAB / SIMULINK AND VERIFICATION OF THE PERFORMANCE OF THE DIGITAL CONTROLLER OF A DC-DC REGULATOR.

THE MAIN ABILITY TO APPLY ACQUIRED KNOWLEDGE WILL BE:
• ANALYZE THE BEHAVIOR OF POWER MANAGEMENT CIRCUITS WITH DIGITAL CONTROL UNDER STATIC AND DYNAMIC CONDITIONS;
• IDENTIFY DESIGN CONSTRAINTS THAT DETERMINE THE SETUP OF A DIGITAL CONTROLLER FOR POWER MANAGEMENT CIRCUITS;
• EVALUATE THE DIGITAL CONTROL CONFIGURATION AND ITS APPROPRIATE PARAMETER SETTING FOR A GIVEN APPLICATION;
• USE CALCULATION AND SIMULATION PROGRAMS FOR THE ANALYSIS AND DESIGN OF DIGITAL CONTROL POWER MANAGEMENT CIRCUITS.

Teaching Methods

TEACHING INCLUDES 24 HOURS OF THEORETICAL LESSONS, 8 HOURS OF NUMERICAL EXERCISES AND 16 HOURS OF PRACTICAL EXERCISES IN THE LAB. NUMERICAL EXERCISES DISCUSS APPLICATION EXAMPLES OF MODELS, METHODS AND ALGORITHMS THAT ARE PART OF THE THEORETICAL LESSONS, AND STUDENTS ARE GIVEN CASE STUDY APPLICATIONS TO BE SOLVED. DURING THE LAB EXERCISES, STUDENTS DEVELOP SYSTEMS AND CONTROL ALGORITHMS OF COURSE POWER MANAGEMENT CIRCUITS, DISCUSSING RESULTS IN COLLECTIVE FORM.
Verification of learning
THE EXAM IS INTENDED TO ASSESS COMPREHENSIVELY THE KNOWLEDGE AND THE ABILITY TO UNDERSTAND THE CONCEPTS PRESENTED IN THE COURSE, THE ABILITY TO APPLY SUCH KNOWLEDGE TO SOLVE DIGITAL CONTROL PROBLEMS OF POWER MANAGEMENT CIRCUITS, JUDGMENT AUTONOMY, COMMUNICATION SKILLS AND THE ABILITY TO LEARN. THE TEST CONSISTS OF AN ORAL COLLOQUIUM. THE COLLOQUIUM IS AIMED AT DISCUSSING THE PROCEDURE FOR SOLVING A DIGITAL CONTROL PROJECT PROBLEM FOR A POWER MANAGEMENT CIRCUIT THAT THE STUDENT DRAWS DURING THE COURSE, BASED ON SPECIFIC ASSIGNMENTS. IN PARTICULAR, THE STUDENT WILL HAVE TO ANALYZE THE STATIC AND DYNAMIC CHARACTERISTICS OF THE CIRCUIT TO BE CONTROLLED, BY MEANS OF THE RELATIVE MODELS DISCUSSED IN THE COURSE, TO CARRY OUT THE PROJECT OF CLOSED LOOP GAIN, DETERMINE THE LAW OF NUMERICAL CONTROL, DETERMINE THE CHARACTERISTICS AND SETTIGS OF THE DIGITAL-TO-ANALOG CONVERTER, THE CPU CLOCK FREQUENCY, AND THE REFERENCE LEVEL REQUIRED TO ENSURE THE REQUIRED PRECISION AND TO PREVENT THE OCCURRENCE OF LIMIT CYCLES, DETERMINE THE CROSSOVER FREQUENCY REQUIRED TO ENSURE THE LIMITATION OF THE VOLTAGE OVERRUN REGULATED DURING LOAD TRANSIENT PHENOMENA WITHIN THE LIMITS SPECIFIED BY THE SPECIFICATIONS. IN THE PROJECT THE STUDENT REPORTS THE FRAMING AND FORMALIZATION OF THE DESIGN PROBLEM, THE RESULTS OBTAINED THROUGH THE DEVELOPED SOLUTION AND THEIR CRITICAL DISCUSSION. THE PURPOSE OF THE COLLOQUIUM IS THEREFORE TO EVALUATE THE ABILITY TO APPLY THE ACQUIRED KNOWLEDGE, THE ABILITY TO FORMALIZE THE PROBLEM AND ITS RESOLUTION, AND THE AUTONOMY OF JUDGMENT. THE EXAM ALSO AIMS TO EVALUATE THE ABILITY TO EXPOSE AND DISCUSS THE CONTENT OF THE DESIGN REPORT AND TO ARGUE THE CHOICES MADE ON THE BASIS OF THE TOPICS DISCUSSED DURING THE COURSE. THE EVALUATION TAKES INTO ACCOUNT THE KNOWLEDGE OF THE STUDENT AND THE DEGREE OF THE IN-DEPTH DEMONSTRATED LEARNING ABILITY, THE QUALITY OF THE PRESENTATION AND THE QUALITY OF THE DISCUSSION. IN THE FINAL EVALUATION, EXPRESSED IN THE SCALE FROM 18 TO 30, WHERE 18 IS THE MINIMUM SCORE AND 30 IS THE MAXIMUM SCORE. THE EXAM IS PASSED IF THE SCORE ACHIEVED IS AT LEAST 18. THE EVALUATION OF THE ORAL DISCUSSION AND OF THE DESIGN REPORT WILL WEIGH EACH 50%. HONORS MAY BE ATTRIBUTED TO STUDENTS WHO DEMONSTRATE THAT THEY KNOW HOW TO APPLY THE ACQUIRED KNOWLEDGE WITH CONSIDERABLE AUTONOMY AND CRITICAL MEANING.
