POWER ELECTRONICS DESIGN
Prerequisites:

In addition to basic knowledge of mathematics and physics, the course makes use of concepts in the fields of circuit theory (properties of electrical networks and fundamental theorems of network theory), electronics (electronic devices, operational amplifiers), and automation (feedback, stability, frequency response, Bode plots). 
Examination methods:

The final examination is divided into two parts:
1  written test (Moodle quiz)
2  oral test
The reports regarding the laboratory activity must be presented before the examination. 
Course unit contents:

 Introduction: description of the course content and organization. Example of power converter systems.
 Power devices: diodes, MOSFETS and IGBTs.
 Conduction and switching losses and thermal considerations.
 Review of converter modeling.
 Peak current mode control: modeling and design.
 Average current mode control.
 Isolated converter topologies: Forward, pushpull, halfbridge, fullbridge and flyback.
 Review of magnetic properties of material: inductors and transformers.
 analysis of highfrequency transformers: skin and proximity effects.
 Inductor and transformer design considerations.
 Input filter design.
 Snubber circuits.
 Layout considerations.
 description of MATLAB/Simulink and PLECS software and their use in the simulation of switching power supplies.
Laboratory activity
 Dynamic begavior of a Boost converter with peak current mode control.
 Losses analysis of a Boost converter.
 Measurements on a flyback converter.
 Measurements on a Forward converter with an active clamp.
