MF1017 Basic Electrical Engineering 6.0 credits

Electrical circuits: DC, AC and transients. Analogy between electrical and mechanical quantities.

Electrical measurements and analog circuits: Measureing with multimeter and oscilloscope. Use of LabVIEW.

Digital electronics and microcontrollers: Transistors in switched and applications.  The functionality of a microprocessor and a microcontroller. Use of microcontrollers in simple applications. Examples of sensors such as encoders and strain gauges.

Electrical motordrives: Single- and three- phase systems. Theory and properties of DC machines. Principles for speedcontrol of electrical machines. Mechanical and thermal transients in electrical machines. Choice of machine size for time varying mechanical loads. Power electronics and drive units for machines. calculation of the required voltage and current for a DC-motordrive.

Sustainable development: Electric and hybrid cars. Calculation of quantities such as e.g. energy, power, force, velocity, acceleration, current and voltage in different parts of a electric or hybrid car under different conditions such as acceleration or regenerative braking. Dimension of energystorages such as batteries and capacitors (ultracap).

After passing the course, the student should be able to:

• Analyze, dimension and use systems that have an electrotechnical part. Examples are electromechanical and / or electrochemical systems.
• Connect circuits, perform measurements and discuss measurement results.
• Design the control of a system of the kind referred to in paragraph 1 above.

Following courses: SF1624 Algebra and Geometry, SF1625 Calculus in One Variable and SF1626 Calculus in Severa Variable, or similar.

Students are expected to have  courses in mathematics compulsory for the T programme

Will be announced at the beginning of the course.

If the course is discontinued, students may request to be examined during the following two academic years.

• INL2 - Assignments, 1.5 credits, grading scale: P, F
• LAB2 - Laboratory work, 2.0 credits, grading scale: P, F
• TEN2 - Written exam, 2.5 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

The examiner decides, in consultation with KTH's coordinator for disabilities (Funka), about possible adapted examination for students with documented, permanent disabilities. The examiner may permit other examination format for re-examination of individual students.

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
