Power Electronics I, Lectures

The objective of the course is to give the basic knowledge on diode and thyristor-based rectifiers, switched-mode converters and active-switch-based rectifiers/inverters. The student can sketch the waveforms associated to the converters. The students can solve the voltage/current stresses for selecting the power-stage components. The students get the knowledge of basic modulation methods of the converters.

Core content

• The operation principle of power semiconductor devices (e.g., diode, thyristor, MOSFET, IGBT).
• The operation of diode-based single- and three-phase rectifiers.
• The operation of thyristor-based single- and three-phase rectifiers.
• The non-isolated switched-mode power converter: buck and boost converter.
• Two-level single-phase half-bridge and full-bridge converters.
• Two-level three-phase converters.
  
• Carrier-based pulse width modulation (CB-PWM).
• Power dissipation and cooling.

Complementary knowledge

• The effect of power converters to the power quality (harmonic analysis).
• Six-step modulation
• The operation principle of buck-boost converter.
• Sinusoidal PWM with 3rd harmonic injection.

Specialist knowledge

• Design of such converters
• The operation principle of GaN MOSFETs.
  
• The operation principle of SiC MOSFETs.
• Natural/stationary/synchronous reference frames
• Space vector modulation

The course will include lectures where main concepts will be introduced. Students need to study reference materials in details since the lectures are meant to cover main topics and give the instructions so that students can understand and continue with reference materials (Books).

There will be calculation and simulation exercises (Matlab based) where you can get extra points by weekly assignments. Advising hours will be organized to help you with calculation and simulation exercises.
