Aim

This course will provide basic knowledge and understanding of electrical circuits and the connection and quantities that describe them. Effective analytical and computational methods for circuits for dc, ac and transients are treated. The course will provide knowledge in electrical power engineering and electrical machinery that the automation and mechatronics engineers need in their profession. The course will also provide some skills in using computer-based analysis tools MATLAB / Simulink and OrCAD.

Learning outcomes (after completion of the course the student should be able to)

  • Master the fundamental laws that govern and quantities that describe electrical circuits: current, voltage, power, energy and Kirchhoff's laws.
  • Explain the function and use of electronic components, and how they are modelled: Resistor, capacitor, inductor (coil), diode, current and voltage sources. Dependent sources (transistors) and linear circuit elements. Differences between ideal and actual components.
  • Master the circuit theorems and methods for analysis of electric circuits: series and parallel connections, voltage and current division, superposition, equivalent Thevenin and Norton circuits, maximum power transfer, node and mesh analysis.
  • Formulate and solve the circuit equations for DC, stationary AC (jw-method) and transient processes in RC and RL circuits (first order systems).
  • Perform calculations on and designing some commonly used circuits like electrical filters, resonant circuits, and active op-amplifier circuits: Transfer functions, Bode plots, frequency charts.
  • Perform calculations and explain the ideal transformer operation: Voltage, current and impedance transformation.
  • Perform calculations on three-phase circuits: Voltage, current, active/reactive-power, power factor correction and Y/Δ-transformation.
  • Explain and describe the function and operation of a DC machine: induced voltage and electromagnetic force action, and perform calculations based on the DC machine's equivalent circuit, both dynamic and stationary.
  • Perform calculations on step-down and step-up power electronic converters, separate and in connection with a dc machine with a mechanical load in an electric drive system.
  • Perform calculations on single phase diode rectifier and describe and explain its function.
  • Apply circuit theory to thermal circuits in steady state for the DC machine, and power electronic components
  • Using computer-based tools (MATLAB / Simulink, OrCAD) for the analysis and design of electrical circuits.
  • Work with projects in small groups and conduct electrical lab work safely.
