Energy management for embedded systems

Objectives

At the end of this module, the student will have understood and be able to explain (main concepts) :
- The characteristics of energy sources likely to be used in embedded systems,
- The methods of energy capture and storage
- circuit topologies for energy management,
- The operational mode of a classical DC motor (actuator) as well as its electrical
and mechanical characteristics.
- The operational mode of an AC transformer and its associated electrical models.
- The main structures and electrical characteristics of single- and three-phase
diode 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:
- To analyse the energy requirements of an embedded system and to devise
a solution,
- To analyse a mechanical system and identify its needs for motorizing, the type
of converter that should be associated with the actuator.
- Design the electrical energy conversion circuit which will
drive the actuator.
- Choose the control strategy for the converter electronic switches in order
to ensure reliable operation

Needed prerequisite

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).

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
