Contents of the course
Theoretical instruction:
- Introductory lecture, production, distribution and conversion of electric power
- The role and importance of power electronics in power distribution and conversion.
- Basic power electronics components: active (power switches SCR, GTO, BJT,MOSFET, IGBT) and passive (coils, transformers, capacitors, ultra/capacitors).
- Voltage and current measurement in power electronics.
- Basics of thyristor phase-control (voltage controller, phase-controlled rectifiers).
- Phase-controlled converters application in controlled motor drives, DC/DC converters (buck converter, boost converter, buck/boost converter, Ćuk converter.
- Chopers and their application in controlled electric motor-drives (industrial drives, traction drives, hybrid and electric vehicles) .
- Power factor correction (PFC) in power electronics. Increasing electric power quality. Basic topologies of PFC and their controllers.
- DC/AC converters, pulse with modulation (PWM), voltage and current fed inverters.
- DC/AC converters in controlled induction motor drives, basics of U/f control, introduction to vector control.
- DC/DC and DC/AC converters in renewable power sources (photo-voltaic, wind generators), basic topologies and controllers.
- Converters for high voltage DC transmition system (HVCD) of power
- Recent trends in power electronics component technology, SIC diodes and MOSFET
Practical instruction (Problem solving sessions/Lab work/Practical training):
- Students independently or with a help of a tutor solve practical issues and tasks in power electronics. Tutorials are in compliance to the lectures. Round visits to the companies dealing with power electronics.
