Mastercollegeserie: Advanced power electronics

Vermogenselektronische omzetters zijn belangrijke bouwstenen voor een breed scala van toepassingen, zoals voedingen voor datacenters, motoromvormers met variabele snelheid, interfaces voor hernieuwbare energiebronnen en hoogspanningsgelijkspanningslijnen. Via methodische analysemethoden en bedrijfstoepassingen leert deze cursus je om converters te ontwerpen.

Het betreft hier een master collegeserie van de Technische Universiteit, speciaal opengesteld voor cursisten van PAO Techniek en Management. Je volgt de colleges samen met reguliere studenten. Deze colleges worden in het Engels gegeven; de informatie hieronder is daarom in het Engels.

The objective of this course is to introduce the necessary knowledge for a more advanced analysis of power electronic components and systems beyond a basic background. The student will learn how to quantify the ideal behavior, and how to deal with some practical limitations of representative power switching circuits by means of manual calculations and computer simulations. Furthermore, lectures and exercises thoroughly discuss key subjects of power electronics that are important with respect to a practical realization and optimization of a power electronic system, e.g. how to select suitable power components, how to determine switching losses, calculation of high frequency losses, EMI filter design and realization, thermal considerations, etc.

Content

Power electronic converters are key building blocks for a wide range of applications, such as power supplies for datacenters, variable speed motor drives, interfaces for renewable energy sources and high‐voltage DC transmissions lines, etc. Through methodical analysis methods, this course attempts to teach students how to design converters and to awaken the students’ creativity to synthesize new converter structures. In all cases industry applications are used as basis of the explanations.

Introduction to power converters and their applications
Non‐isolated DC‐DC converters
Power semiconductor devices + loss calculations
Modeling and dimensioning of inductors and transformers
