Objectives
THE ADVANCED FEATURES OF COMPUTER AIDED DESIGN (CAD) OFFER A WIDE VARIETY OF BENEFITS TO ELECTRICAL ENGINEERS, FROM SPEED AND EFFICIENCY OF PROCESS THROUGH TO THE COST-EFFECTIVENESS OF PRODUCTION, AND THEY SUPPORT THE DEVELOPMENT OF INNOVATIVE SOLUTIONS.
THIS COURSE PROVIDES THE ESSENTIAL TOOLS FOR THE DESIGN AND OPTIMIZATION OF ELECTRICAL DEVICES (SINGLE COMPONENTS AND COMPLEX SYSTEMS), WITH SPECIAL FOCUS ON CAD-SIMULATIONS THAT ALLOW ENGINEERS TO TEST THE THEORETICAL PERFORMANCE OF THE COMPONENTS THAT THEY'RE MODELLING AND PROVIDING ELECTRICAL FUNCTIONAL SCHEMES AND REPORTS OF FINAL PROJECTS.
THE FIRST PART OF THE COURSE GIVES AN OVERVIEW OF THE MAIN PHYSICS PHENOMENA TO TAKE INTO ACCOUNT IN THE ANALYSIS AND DESIGN OF ELECTRICAL SYSTEMS.
THE SECOND PART WILL BE AIMED AT THE DESCRIPTION OF NUMERICAL METHODS AND APPROACHES USED IN COMMERCIAL CAD SOFTWARE TO ACCOMPLISH OPTIMAL DESIGN OF ELECTRICAL COMPONENTS AND SYSTEMS. THE STUDY OF ELECTRICAL SYSTEMS WILL BE PERFORMED BY USING MULTIPHYSICS MODELS AND OPTIMIZATION TECHNIQUES BUILT-IN IN CAD (E.G. COMSOL MULTIPHYSICS, SOLIDWORK ELECTRICAL 3D) AND USED FOR VIRTUALIZATION OF ELECTRICAL DEVICES AND SYSTEMS, BY INCLUDING 3D MODELS.
THE THIRD PART WILL BE DEVOTED TO THE DEVELOPMENT OF A SPECIFIC ELECTRICAL APPLICATION.
THE STUDENTS WILL BE EVALUATED ON THE BASIS OF A PRACTICAL PROJECT USING A COMMERCIAL ELECTRICAL CAD.

TOTAL LECTURE/PRACTICE/LABORATORY HOURS 32/16/0
Teaching Methods
THE COURSE INCLUDES 48 HOURS OF LESSONS (6CFU) DIVIDED BETWEEN 32 HOURS OF CLASSROOM LESSONS (4CFU) AND 16 HOURS OF EXERCISES (2CFU).
THE LECTURES WILL ALLOW THE STUDENT TO ACQUIRE THEORETICAL AND PRACTICAL KNOWLEDGE. THE EXERCISES WILL ALLOW THE STUDENT TO DEVELOP THE ABILITY TO APPLY THE THEORY. THE TEACHING ALSO INCLUDES THE DEVELOPMENT OF AN INDIVIDUAL PROJECT AIMED AT ACQUIRING THE ABILITY TO DESIGN AND OPTIMIZE ELECTRICAL SYSTEMS THROUGH MULTIPHYSICS CAD SIMULATIONS.
Verification of learning
THE LEVEL OF ACHIEVEMENT OF THE TEACHING OBJECTIVES IS CERTIFIED BY PASSING AN EXAM AT THE END OF THE TEACHING (DURATION: APPROXIMATELY 30 MINUTES). THE EXAM INCLUDES THE DEVELOPMENT AND DISCUSSION OF A PAPER THAT ILLUSTRATES, BY MEANS OF A 20-MINUTE PRESENTATION AND A FOLLOWING 10-MINUTE DISCUSSION, THE SOLUTION OF THE ENGINEERING PROBLEM PROPOSED AND SET DURING THE EXERCISE HOURS.
THE EXAM CONSISTS IN PARTICULAR IN THE CREATION OF A PRACTICAL PROJECT DEVELOPED USING THE ELECTRICAL CAD PROGRAM PROVIDED (WEIGHT 0.5 ON THE FINAL GRADE AND AIMED AT VERIFYING THE ABILITY TO DESIGN), IN THE DRAFTING OF A TECHNICAL REPORT RELATING TO THE PROJECT (WEIGHT 0.1 ON THE FINAL GRADE AND AIMED AT VERIFYING THE ABILITY TO REPORT IN A TECHNICAL MANNER) AND IN THE ORAL PRESENTATION OF THE SAME (WEIGHT 0.4 ON THE FINAL GRADE AND AIMED AT VERIFYING THE ABILITY TO EFFECTIVELY PRESENT THE DEVELOPED PROJECT AND CRITICALLY DISCUSS ITS SALIENT ASPECTS). THE EXAM SCORE DEPENDS ON THE DEGREE OF DEPTH OF THE PROJECT, ON THE STUDENT'S ABILITY TO EFFECTIVELY PRESENT ITS CONTENTS BOTH IN WRITTEN AND ORAL FORM, AND ON THE ABILITY TO CRITICALLY DISCUSS THE TOPICS ILLUSTRATED.
THE MINIMUM SCORE INCLUDES THE CREATION OF A PROJECT THAT ADDRESSES THE SOLUTION OF THE MINIMUM SPECIFICATIONS ASSIGNED, THE DRAFTING OF A REPORT THAT CONTAINS THE ESSENTIAL ELEMENTS OF A TECHNICAL REPORT ACCORDING TO QUALITY STANDARDS AND THE DISCUSSION OF THE PROJECT ITSELF WITH THE DEFINITION OF THE MINIMUM ELEMENTS AND THE CRITICAL ISSUES THAT EMERGED.
THE MAXIMUM SCORE IS ACHIEVED WHEN THE STUDENT CREATES A PROJECT THAT MEETS THE MINIMUM SPECIFICATIONS ASSIGNED, PREPARES AND DELIVERS A TECHNICAL REPORT COMPLETE WITH THE NECESSARY DESCRIPTIVE ELEMENTS ACCORDING TO QUALITY STANDARDS, AND DISCUSSES THE PROJECT ITSELF ORALLY IN AN EFFECTIVE AND CRITICAL MANNER. EXCELLENCE REQUIRES COMPLIANCE WITH THE REQUIREMENTS VALID FOR THE MAXIMUM SCORE AND THE DEMONSTRATION OF BEING ABLE TO EFFECTIVELY GO BEYOND THE MINIMUM SPECIFICATIONS IMPOSED. THE FINAL GRADE IS IN THIRTIETHS AND WILL RESULT FROM THE WEIGHTED AVERAGE OF THE THREE EVALUATION ELEMENTS.
