Learning outcomes
This module allows the student to deepen the theoretical elements acquired in the classroom during the course of Industrial Electronics with laboratory experiments. In particular, the student consolidates the acquired knowledge by verifying the working of signal conditioning circuits from sensors both through circuit simulation CAD tools and through measurements using basic electronic instrumentation. The student also learns to perform measurements on power conversion circuits as the ones used in the industrial field for powering and controlling machines.
Course contents
Main performance figures of merit in analog circuits. Fundamental circuit specification and classification for signal conditioning and power conversion.
Practical exercises on LTSpice circuit simulator for various types of analysis: Bias-point, Transient-Analysis, DC-sweep, AC-sweep, parameter-sweep; result post processing tools and results interpretation: diagnostic files, FFTs, sub-circuits and imported models.
Main passive (resistors, capacitors, magnetic) and active components (generators, switches, diodes, transistors, operational amplifiers) and their models.
Signals and power adaptation. Filters for frequency behavior shaping and Safe Operating Area for reliability. Equivalent thermal circuit and sizing of heat sinks. Protection devices. Isolations.
Rectifiers (AC/DC), Stabilizers (DC/DC), Linear Regulators and Linear Amplifiers, Buck/Boost Switching Regulators and Power Supplies. LEG switching and feedback. Inverters (DC/AC) and switching amplification. Motor driving circuits.
Readings/Bibliography
Professor handout notes, lecture notes, components datasheets and constructors application notes.
Teaching methods
Computer-assisted frontal lessons with an approach that goes from the detail of the specific problem (answer, solution, analysis) to the general of a possible approach to design (question, method, synthesis).
Assessment methods
The exam consists of a practical test on LTSpice in interaction with the teacher.
The verification test consists in running a simulation from scratch in order to verify the circuit implementation and correctly understand the simulation results with the aim of achieving the required performance specifications.
The ability to use the circuit simulator and the understanding of the circuit operations are assessed by means of comparative discussion of simulations with varying components value and changing simulation results performance desiderata.
Teaching tools
LTSpice simulator is the main teaching support tool.
Other resources to support teaching derive from browsing the main manufacturers' sites in search of documentation relating to component technologies.
