First of all, I would like to express my sincere gratitude to Saeid Haghbin, my supervisor, for his total availability during the thesis, for his understanding, technical guidance and friendliness.
My gratitude also goes to Ola Carlson, for giving me the opportunity to do this Master’s Thesis work in the Electric Power division of Chalmers University of Technology.
A very special thanks to Stefan Lundberg and Massimo Bongiorno, for all help, their availability, technical guidance and nice discussions.
Thanks to all the employees and staff in the division who made my thesis work such a pleasant stay. Furthermore, I would like to thank Magnus Ellsen for his availability and help for laboratory set up.
Finally, many thanks to my fellow Master’s Thesis students with Saman Babaei, Thinley Gyeltshen, Francisco Montes Venero, Peng Hou, Sergio Garcia Collino and Johan Andersson. Thanks for their support, guidance and nice discussions. They also made my stay in Sweden an unforgettable experience.
