Why take this course?
The growth of humanity, from less than 2 billion in the end of the 19th century to over 7 billion in the beginning of the 21st
century is strongly related to our ability to use energy. The use of
fossile energy cause severe problems with the environment and is truly
challenging the future of man kind. We strongly need I) to reduce our
use of energy and II) to transfer from fossil and probably nuclear to
renewable energy sources. This is where Power Electronics is important. Independent of primary energy source, a lot of our use of energy involves electric energy technology. Manufacturing, transport, lighting, ventilation, heating, electricity transmission, physics research, ... all involve one or several steps where the energy is converted to electricity before finally consumed. In addition, renewable energy sources like wind, wave and solar are entirely dependent on conversion of the primary energy source to electricity as an intermediate state before finally consumed.
In
most, if not all, of these applications the energy is converted by
means of switching power electronics converters built by power
semiconductors and controlled in real time by very fast control
systems. The development of modern power electronics started half a
century ago and is today developing faster than ever before. As an
engineer with ambitions to work with, or just understand the fundaments
of, electric energy conversion and control, it is important t study
power electronics - it is involved "everywhere" in electric energy flow
control.
This course is given to provide a deep understanding of the technologies involved, the requirements and limitations, the opportunities and to give the understanding and tools to help those who want to contribute to the development.
The
course is built on lectures,labs, exercises. The labs are prepared
within the Matlab/Simulink environment such that you by the computer
get a chanse to understand the dynamic behaviour that you will se on
instruments in the lab.
Teachers
The
course is given by Professor Mats
Alaküla.
The course is assisted by Akanksha Upadhey, Max Collins and Samuel Estenlund, all PhD students at IEA.

2020-01-27:All lecture invitations are now updated as session-specific. Thus, you need to log in to each event with a unique Zoom-link, sent by mail.All teaching will be made via Zoom, until further notice, as a consequence of the Corona pandemic.This course is lab-intensive, with 6 different labs that each of them contain prestudies in the form of simulation work, and laboratory exercises, both of which involves report writing. As long as the Covid-situation does not lighten, all these labs will be run in a virtual form, based on pre-recorded lab activities that the student will evaluate and analyse to build the lab reports on.IF the Corona restrictions lighten enough, teaching may return to normal class room / lecture hall sessions as well as physical labs again. The teaching sessions will be recorded and made available to download from this page. Contact
