The course is devoted to students of the Industrial Automation (2. level
degree) and is aimed at providing students with the basis for the
understanding, the choice and the use of power converters for electrical
actuators, and of its ancillary equipment and components. It also
presents and discusses the main optical measurement systems, and the
most modern techniques for 2D and 3D vision.
The course is divided in three parts.
In the first part the components for power electronics are briefly
presented.
In the second part the main power converters (AC-DC, DC-DC, DC-AC,
resonant converters) and the uninterruptible power supplies are
presented and discussed.
In the third part, after a brief survey of optical and optoelectronic
components, an outline is given of the most popular optical measurement
techniques and of the techniques for 2D- and 3D vision systems for inand off-line dimensional control, including the most modern vision
techniques for the 2-D and 3-D vision, aimed at dimensional control and
reverse engineering.

electronic components. The problem of energy dissipation of power
components.
Power electronics converters
