Lecture "Energy Converters - CAD and System Dynamics"

Written exam:

• The exam contains 3 exercise questions (30 min x 3), and 3 theory questions (10 min x 3). Total exam time is 120 min. Between theory and calculation part there will be a break.
• Write your solutions at the designated space. Your solutions must be readable and comprehensible. Double solutions will not be considered.
• Points are given to both correct formulas and results.
• Do not write on your own paper. If you need additional sheets, please ask the supervisor.

Permitted aids during theory questions:

• Scientific pocket calculator, no graphing or programmable calculators.
• Rulers, pencils, except of red colour.

The use of other resources will be treated as an attempt of deception.

Permitted aids during exercise questions:

• Scientific pocket calculator, no graphing or programmable calculators.
• Rulers, pencils, except of red colour.
• Four pages (= two sheets) of handwritten formulas. No print-outs, no photocopies. Drawings and sketches are also allowed, but not complete solutions of exercises.
• The textbook “Energy Converters – CAD and System Dynamics”. Handwritten annotations are allowed, but no solutions of exercises.

The use of other resources will be treated as an attempt of deception.

General warning: No computers, mobile phones, smart watches and other electronic devices.

Bonus System: Homework

• You must write the solution of your homework by hand. Your name and your matriculation number must be clearly written on your homework
• The homework sheets and their due dates will be available in the Moodle course from the beginning of the semester.
• If all homeworks are completely and correctly solved, you get a final mark, which is one mark better than your result from the written exams (improvement by 1,0). Your actual bonus is proportional to your percentage of correctly solved homeworks. In order to pass the module you need to reach at least a grade 4,0 in the written exams without bonus.
• The bonus points are valid only for 1 year (1x WiSe and 1x SoSe).
