Electric Circuit Theory

Course title: Electric Circuit Theory

Code: FEIT05Z001

Number of credits (ECTS): 6

Weekly number of classes: 3+2+0+0

Prerequisite for enrollment of the subject: None

Course goals/Competences: The goal of this theoretical discipline is to offer the students a broad platform, set on mathematical foundations, on which they can build up their knowledge through the courses from the field of power engineering. With the successful completion of the course the student will be able:

- To successfully analyze electric circuits in time and frequency domain

- To distinguish the different circuit’s responses and states

- To analyze circuits with complex topological structure

- To analyze three phase circuits, short circuit current calculation, transmission lines

Total available number of classes: 180

Curriculum: Basic definitions and laws: circuits elements, Kirchhoff’s current law, Kirchhoff’s voltage law, power classifications.  Analysis in time domain: convolution, impulse and step responses, circuits response (components), node analysis and mesh analysis. Analysis in frequency domain: complex numbers, sinusoidal steady-state analysis, the Fourier series, the Laplace transform (definition, convergence, properties), the inverse Laplace transform (partial fraction expansion), circuit analysis with Laplace transform. Electric networks: definition, transfer functions, two-port networks. Three-phase circuits: unbalanced three-phase circuits, symmetrical components, short circuit calculation using symmetrical components. Transmission lines: wave equations, sinusoidal steady-state analysis
