Objectives
THE COURSE PROVIDES THE MAIN TECHNIQUES FOR THE EVALUATION OF ELECTRICAL IN CIRCUITS COMPOSED IN DYNAMICAL CONDITIONS IN TIME AND FREQUENCY DOMAINS. THE PROPERTIES OF THREE PHASE CIRCUITS ARE DISCUSSED. THE CHARACTERISTICS OF ELECTRICAL COMPONENTS ARE OBTAINED FROM FIELD QUANTITIES; THE EQUIVALENT MODELS AS A FUNCTION OF FREQUENCY ARE PRESENTED.
Prerequisites
A PRIOR KNOWLEDGE OF THE FOLLOWING TOPICS IS REQUIRED:
- SOLUTION METHODS FOR LINEAR CIRCUITS IN DC AND AC
- BASIC PHYSICS CONCERNING ELECTRIC AND MAGNETIC FIELDS
- SOLUTION METHODS FOR LINEAR DIFFERENTIAL EQUATIONS.
Contents
DYNAMIC TWO-PORTS (10H LECTURES, 5H EXERCISE). MUTUAL INDUCTANCE AND COUPLED CIRCUITS EQUATIONS. IDEAL TRANSFORMERS. EQUIVALENT CIRCUITS FOR REAL TRANSFORMS. MAGNETIC CIRCUITS. EVALUATION OF AUTO AND MUTUAL INDUCTANCES FOR SIMPLE MAGNETIC STRUCTURES.

TIME DOMAIN SOLUTION OF DYNAMIC (FIRST AND SECOND ORDER) LINEAR TIME INVARIANT CIRCUITS (10H LECTURES, 10H EXERCISE, 5H LAB SIMULATIONS). ZERO-STATE AND ZERO-INPUT RESPONSE. STEP AND DIRAC DELTA FUNCTION. EVALUATION OF THE IMPULSE RESPONSE. CONVOLUTION INTEGRAL.

FREQUENCY CHARACTERISTICS OF ELECTRIC CIRCUITS (5H LECTURES, 3H EXERCISE, 2H SIMULATION LAB). LAPLACE TRANSFORM, OPERATIONAL IMPEDANCE; TRANSFER FUNCTION; INVERSE TRANSFMORMATION; NETWORK FUNCTIONS, RESONANCE IN RLC CIRCUITS.

AC THREE PHASE CIRCUITS (5H LECTURES, 5H EXERCISE). STAR AND DELTA CONNECTED LOADS; BALANCED AND UNBALANCED SYSTEMS; POWER IN THREE PHASE CIRCUITS. POWER FACTOR CORRECTION.
Teaching Methods
THE COURSE INCLUDES CLASSROOM LECTURES AIMED AT PRESENTING THE THEORY AND NUMERICAL EXCERCISES TO STRENGTHEN THE OPERATIONAL SKILLS. THE EXERCISES ASSIGNED TO STUDENTS ARE SOLVED IN CLASS BY THE TEACHER USING THE TECHNIQUES PRESENTED IN THEORY LECTURES. THE EXCERCISES ARE LED BY THE TEACHER TO DEVELOP THE PUPIL'S ABILITY TO IDENTIFY THE MOST APPROPRIATE SOLUTION TECHNIQUES AND PRESENT THE RESULTS IN A CLEAR AND EFFICIENT WAY.
Verification of learning
THE ASSESSMENT OF THE ACHIEVEMENT OF LEARNING OBJECTIVES IS CARRIED OUT BY AN EXAM COMPOSED OF A WRITTEN AND AN ORAL TEST. A MININUM GRADE OF 18/30 HAS TO BE OBTAINED AT THE WRITTEN TEST TO PROCEED TO THE ORAL EXAM.

- THE A WRITTEN TEST IS DESIGNED TO EVALUATE THE OPERATIONAL CAPABILITIES IN SOLVING CIRCUITS (MAINLY 2ND ORDER DYNAMIC CIRCUITS AND THREE-PHASE CIRCUITS). - THE ORAL EXAMINATION IS AIMED AT VERIFYING THE LEVEL OF THE THEORETICAL KNOWLEDGE AND SKILLS GAINED BY THE STUDENT.

THE FINAL SCORE (MIN 18/30, MAX 30/30 PLUS LAUDE) WILL DEPEND ON THE PARTIAL SCORES OF THE TWO TESTS. THE EXAMINER MAY DECIDE WHETHER PARTICULAR STRENGTHS AND WEAKNESSES COMPENSATE EACH OTHER.
