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. Single- and three-phase transformers (equivalent circuits, characteristics). 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). Introduction to electronic converters (AC-DC, DC-DC, AC-DC, AC-AC).

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.

This course contributes to the learning outcomes I.1, I.2, II.1, III.1, III.2, IV.2, V.1, V.2, VI.2, VII.2, VII.4, VII.5 of the BSc in engineering.

Prerequisite knowledge and skills

Planned learning activities and teaching methods

Theory lectures, excercise sessions and 4 laboratory sessions.

The laboratory sessions are mandatory.

Mode of delivery (face to face, distance learning, hybrid learning)

Face-to-face course

Course materials and recommended or required readings

Lecture notes available on the course website.

Exam(s) in session

Any session

- In-person

written exam

Further information:

Grade weighting:

one in-term test (weighting: 5%)
a quiz at the end of each lab session (weighting: 15%)
written exam (weighting: 80%)

Important: Attendance at all lab sessions is mandatory. Any unjustified absence from one of these lab sessions will result in an "absence" grade for the entire course during the first exam session. The student may still take the exam in the second session, but a zero will be applied for the missed lab(s).
