Subject fundamentals
The course aims to introduce the main concepts of the circuital analysis of the electric and magnetic phenomena, with particular attention to aspects of DC and low frequency. In the first part will be given the methodological bases for understanding the working principles and key operational concepts of electromechanical equipment and in general a rational, proper and safe operation of electrical equipment
Expected learning outcomes
Master the key concepts of circuit analysis, quantitative assessments of ability to perform simple electrical circuits industry, understand usage patterns and the main fields of application of electrical machinery and know how to cope with simple numerical problem regarding electrical applications.
Prerequisites / Assumed knowledge
The course considers acquired concepts in ordinary differential equations, complex numbers and electromagnetism.
Contents
1. Circuit analysis of electromagnetic phenomena: electrical circuits as a model of physical phenomena, the concept of port, the electrical voltage, current and power, units and measuring instruments, brief to the topology of the circuits, Kirchhoff's laws, basic assumptions of the model circuit .
2. Adynamic Circuits: constitutive equations of an ideal resistor, ideal voltage and current generators, short circuit and open circuit, series and parallel connections, voltage and current divider, star-delta transformations, non-ideal components. Power and energy in the circuits.
3. Methods for the solution of adynamic generic circuits: algebraic methods. Network theorems (superposition theorem, circ. Thevenin and Norton equivalent, Millmann, Tellegen's theorem).
4. Elementary components and circuit dynamics. Dynamic components: capacitors, inductors, coupled inductors and ideal transformer. State variables. Transient in RC and RL circuits.
5. Circuits in sinusoidal steady state: phasor method, Kirchhoff's laws and constitutive equations in the frequency domain, impedance and admittance of the ports. Active, reactive, and complex power. Boucherot theorem, power factor correction.
6. Three-phase systems: definitions, three phase generators and loads, star and delta connections, methods of solution. Power in three-phase circuits and its measure.
7. Introduction to Electrical Safety.
