Energy management for embedded systems

Description

Objectifs

-     At the end of this module, the student will have understood and be able to explain (main concepts):

-     The performances of energy sources likely to be used in embedded systems,

-     The methods of energy capture (harvesting / scavenging)

-     circuit topologies for embedded energy management,

-     The operation mode of a classical DC motor (actuator) as well as its electrical and mechanical characteristics.

-     The operation mode of a AC transformer and its associated electrical models.

-     The main structures and electrical characteristics of single and three phase rectifiers.

-     The main structures of choppers, their properties, their reversibility and control strategies.

-     The principle of torque and/or speed control of a DC machine using a chopper

The student will be able to:

-     Analyze the energy requirements of an embedded system and to devise a solution,

-     Analyze a mechanical system and identify its needs for motorizing, the type of converter that should be associated with the actuator.

-     Dimension the elements of the electrical energy conversion chain which will drive the actuator.

-     Choose the control strategy for the electronic switches of the converter in order to ensure its reliability.

Pré-requis

General knowledge of electricity, alternating current, electrical circuits, analog and digital electronics as well as mathematical tools (Fourier and Laplace transforms) and the basics of automatic control (transfer functions and block diagrams).

Évaluation

L’évaluation des acquis d’apprentissage est réalisée en continu tout le long du semestre. En fonction des enseignements, elle peut prendre différentes formes : examen écrit, oral, compte-rendu, rapport écrit, évaluation par les pairs…
