Type of course

Course content

The course will describe the design, operation, and control of electrical energy converters. Electric transportation, renewable energy and energy storage will be used as application of power converters throughout the course. The emphasis is on control algorithms and dynamic operating characteristics.A design project will be completed in groups. Laboratory and experiments is a central and integrated part of the course, including the project work.

Power conversion:

• Converter circuit topologies
• Modulation strategies
• Dynamic models
• Active and reactive power control
• Predictive control algorithms

Motor drives:

• Mechanical and electrical modelling.
• Dynamic operating characteristics.
• Advanced control strategies of AC drives based on vector control and direct torque control.

Assessment

Courswork / Course requirements

- Completed the required HSL courses within laboratory work and safety is required be approved before gaining access to the laboratory.

- 1 (out of 1) mandatory digital test in measurement techniques and correct use of laboratory equipment.

- 1 (out of 1) course evaluation form submitted

- 4 (out of 4) approved laboratory exercises.

- 1 written project report submitted for review

- 1 approved peer review of another groups’ project report

Examination and assessment

The assessment is based on :

• Written project report (50 %)
• Oral examination (50 %)

Both parts needs to be passed individually to pass the course.

Grading is scaled from A (highest) to F (lowest), with E as the minimum pass grade.

Re-sit oral exam will be arranged if any candidate received grade F in the previous ordinary exam. No re-submission of the project report is offered.
