Basics of Electricity and Electronics

Thévenin and Norton equivalents;
Inductances and capacitances;
Alternating current (AC);
Active, reactive and apparent powers;
Three-phased systems: symmetrical voltages, currents and power.
Power factor correction techniques in mono and three-phased systems.

Semiconductors – power bands; mobility and conductivity. Notion of dopant, acceptors and donors.
Semiconductor diode – PN junction and its characteristics; principle of operation, characteristic curves and applications. Rectifier diode, Schottky, Zener, LED and photodiode. Applications: limiting circuitry, single-phase rectifiers: half-wave, full-wave and bridge, capacitive filtering.
Bipolar Junction Transistors (BJT) – Internal constitution and principle of operation. Characteristic curves and operating regions: off, active and saturation. Polarization and stability of the operating point. Application circuits.
Field Effect Transistors (FET) – Types of FETs: Junction and MOS and its internal constitution. Characteristic curves and operating regions. Polarization and stability. Application circuits. Power Interfaces. Other applications.

This unit aims introducing students to the fundamentals of electricity and electronics giving them the competences to the analysis of DC and AC electrical and electronic circuits. In this unit students will also focus on the techniques (and devices) used to the measurement of main electrical quantities (current, voltage and power). In the electronics field, the unit will focus on diodes, bipolar transistors and field effect transistors.
Skills acquired are: Knowledge and use of main electrical measurement and test devices; Understanding, projecting, operating and maintaining electrical and electronic devices.

Introduction to DC current (electrical charges, electrical fields, voltages, currents and ohmic elements, sources);
Ohm’s law;
Kirchhoff Laws;
Voltage and current dividers
Large circuits solving technics
Superposition principle.
