Electric Power Converters Course code: 120507 | 6 ECTS credits

Basic information
Level of Studies:
Year of Study: 3
Semester: 6
Requirements: Basic knowledge's from the electroenergetics, electronics and mathematics
Goal: Acquiring the basic knowledge of power semiconductor components, electronic circuits for converting electrical energy and their functioning, as well as acquiring sophisticated knowledge's for basic methods of analysis of power converter circuits. Application of acquired theoretical and practical knowledge for the purpose of concrete application in the process industry and electric power industry.
Outcome: Students will be able to apply acquired knowledge in the design, use and maintenance of power converters (various types of rectifiers, inverters and choppers).
Contents of the course
Theoretical instruction:
  1. Introduction lecture; Basic characteristics of switching devices which applied in power electronics

  4. Rectifier with power factor correction (PFC)
  5. Single-phase and three-phase AC/AC power converters (voltage adjusters)
  6. Power converters for compensation of reactive power
  7. Power converters for charging/discharging of various types of batteries (lead acid, Li-Ion, NiMH, NiCd); the basic structure and control circuits
  8. DC/DC power converters: step-down ("buck"), step-up ("boost"), step up-step down ("buck-boost"), Cuk converter, SEPIC converter
  9. The chopper circuits for speed control of DC motors
  10. DC/AC power converters, single-phase, with SCR and IGBT switching devices
  11. Pulse Width Modulation (PWM) applied on the single-phase inverters; output filter dynamics
  12. Three-phase DC/AC power converters; output filter dynamics
  13. Frequency converters (AC/DC/AC) ant their applications in controlled AC drive
  14. High frequency power converters in the systems of induction heating
  15. High voltage high frequency power converters and their application in ESP stations on thermal power plants
Practical instruction (Problem solving sessions/Lab work/Practical training):
  1. Practical instruction consists of a) Computational exercises: solving practical tasks according to lecture contents (b) Computational exercises: simulations (in the PSPICE-MicroSIM program package) of power converters according to the content of the lectures (c) Laboratory exercises that are in accordance with the lectures
