Course contents

The teaching has essentially a formative and basic character for the Engineering studies. The subject of teaching is subdivided into three chapters: Electromagnetism, Circuit Theory, Electric Machines.

Electromagnetism: Magnitudes and equations of the electromagnetic field: their definition and physical meaning - fundamental Lobbies of the Electromagnetism: laws of Maxwell, law of Gauss and law of divergence, law of conservation of the charge - laws of material bond.

Circuit theory: circuit element and electric circuit, Kirchhoff's laws and descriptive laws of the ideal elements: the resistor, the capacitor and the ideal inductor, the independent generators and the piloted generators - Methods of circuit analysis: general method of analysis , method of elimination of tensions, method of nodes, principle of superimposing effects - Transfer function, Thèvenin theorem, Norton's theorem - Tellegen's theorem and power adversities - Sinusoidal regime: phasor, resonance and antirisonance method, powers active and reactive, the rephasing of a two-port - Frequency response and main passive filters - Three-phase systems - Magnetic circuits, auto and mutual induction coefficients, magnetic energy and magnetic force calculation, ferromagnetic materials

Electric Machines: The Transformer - General Methods for the Study of Rotating Machines, the Rotating Field - The Asynchronous Machine - Collector Machines - Overview of Synchronizing Machines.

Readings/Bibliography

Lecture notes are available prepared by the teacher on the teacher's web pages. The slites projected during the lectures are available on the web site too.

The following texts are recommended as a consultation thesis:

  • C.A. Desoer, E.S. Kuh, "Fundamentals of circuit theory", Ed. Angeli, Milan
  • L.O. Chua, C.A. Desoer, E.S. Kuh, "Linear and non-linear circuits", Jackson books, Milan
  • K. Alexander and M.N.O. Sadiku, "Fundamentals of Electric Circuits", McGraw Hill, New York, 2009
  • G. Rizzoni, "Principles and Applications of Electrical Engineering", McGraw Hill, New York, 2007
  • F. Ciampolini: "Elettrotecnica generale", Ed. Pitagora, Bologna
  • P.R. Ghigi, M. Martelli, F. Mastri, "Exercises of Electrotechnics", Ed. Esculapio, Bologna

Teaching methods

The course is based on theoretical lessons and exercises.

Assessment methods

The verification is obtained by means of a written exam that concerns both the theory and the exercises of the type treated during the lessons. If requested by the student, when a positive result is obtained in the written exam, an oral interview can be added.

Teaching tools

In professor Borghi's teaching website (http://www.die.ing.unibo.it/pers/borghi/didattica.htm) notes on the course topics are available. This site also includes slides projected during the lessons, exercises and other information.
