EE-365 / 4 credits

Teacher: Dujic Drazen

Language: English


The goal of the course is to present fundamentals of power electronics. The key focus is on the operating principles of power electronic converters, their modelling, sizing and design.



  • Power electronics and its role in energy conversion
  • Power semiconductor devices (diodes, thyristors, BJT, MOSFET, IGBT, IGCT,..)
  • AC-DC converters - diode rectifiers, phase-shift controlled thyristor rectifiers
  • DC-DC converters (non-isolated) - Buck, Boost, Buck-Boost, Cuk, SEPIC
  • DC-DC converters (isolated) - Flyback, Forward, Push-Pull, Dual Active Bridge, Resonant Converters
  • DC-AC converters - single-phase and three-phase inverters
  • AC-AC converters - single stage, double stage conversion, frequency converters
  • Pulse Width Modulation (PWM) - basic principles, unipolar and bipolar PWM, three-phase PWM
  • Passive components - design of inductors and transformers
  • Thermal design - losses in semiconductors and passive devices, thermal networks, cooling system design
  • Power electronics simulations, design and integration
  • Power electronics applications: electrical drives, renewable electrical energy, electrical traction, power supplies



electrical energy conversion, power electronics, converters, modeling and design


Learning Prerequisites

Required courses

Energy conversion

Learning Outcomes

By the end of the course, the student must be able to:

  • Understand a power electronics system
  • Understand the operation of power electronics applications
  • Design a power electronic converter for a given specifications
  • Define a power electronic converter for a given application
  • Develop a power electronic converter
  • Model power electronics systems
  • Characterize power semiconductors and power electronic converters

Transversal skills

  • Demonstrate the capacity for critical thinking
  • Plan and carry out activities in a way which makes optimal use of available time and other resources.
  • Access and evaluate appropriate sources of information.
  • Use a work methodology appropriate to the task.
  • Write a scientific or technical report.

Teaching methods

Lectures will present relevant theoretical background, basic principles and new concepts, modeling and simulation examples (using PLECS simulation SW) as well as numerical examples to illustrate power electronic designs. Comprehensive slides will be available on Moodle.

Exercises are implemented as Project based assignment. Grouped in pairs, students will receive project assignment for the whole semester. Project will involve practical design of a small power electronic converter, with modest power ratings and utilizing commercially available IC for control (there is no need for programming of any kind). Writen report and working prototype are expected at the end of a course.

Additional training sessions will be provided by Power Electronics Laboratory so support student's projects (e.g. PLECS and ALTIUM trainings).

Expected student activities

In addition to attending lectures, where theoretical foundations will be presented, throughout the semester, student's work will involve several activites, required to finalize the assignement:

- understanding operating principles of the given topology

- simulations to verify operation and performances under rgiven operating conditions

- design (inductors and/or transformers) and selection of components (semiconductors, resistors, capacitors)

- schematic and printed circuit board design (in Altium)

- practical assembly and testing (in PEL laboratory ELH-114)

- design documentation and final report writing

Assessment methods

Project presentation including:

- written design and test report

- final oral presentation and discussion including demonstration of the converter operation
