Learning unit contents

Description of the course:
Based on the fundamental principles of physics, this course explores the conversion mechanisms of electromagnetic energy. Applications studied cover transformers and different types of electrical machines : synchronous, asynchronous and DC.
Table of contents:
Fundamentals laws of electromagnetism, magnetomotive and electromative forces, electric and magnetic circuits, single- and three-phase sinusoidal regimes, rotating fields, hysteresis and eddy current losses.
Electric conversion: single- and three-phase transformers (equivalent circuits, characteristics), introduction to electronic converters (AC-DC, DC-DC, AC-DC, AC-AC).
Electro-mechanical conversion: synchronous machines (equivalent circuits, torque, operation on a network), asynchronous machines (equivalent circuits, torque, efficiency, circle diagram, startup, speed control), DC machines (characteristics, torque, startup, speed control)

Learning outcomes of the learning unit

At the end of the course the student will be able to understand electrical energy conversion phenomena, and will possess the necessary tools to analyze them in a quantitative manner using simple circuit-type models.

Prerequisite knowledge and skills

Basic physics course

Planned learning activities and teaching methods

Theory lectures, excercise sessions and laboratory sessions.
The laboratory sessions are mandatory. Non justified absence to any laboratory session will lead to failure (with an "Absent" grade) for the whole class.

Mode of delivery (face-to-face ; distance-learning)

Face-to-face.

Recommended or required readings

Lecture notes available on the course web site.

Assessment methods and criteria

Tests during the laboratory sessions (20% of the final grade) and oral exam (80% of the final grade).
In case of failure during the first exam session, only the oral exam can be taken again during the second exam session; the grades obtained for the laboratory tests are final.
