By Hirofumi Akagi
Title : New Trends in Power Electronics for High-Power Applications
Speaker : Prof. Hirofumi Akagi, Tokyo Institute of Technology, Tokyo, Japan
Date and time : Monday 15th December, 15:00 - 17:00
Venue : KTH Royal Institute of Technology, Stockholm, Lecture Room M33
This talk lays emphasis on an overview of circuit configurations, controls and applications of the family of modular multilevel cascade converters for grid connections and electric-motor drives. It also presents experimental results obtained from a few different downscaled systems that were designed, constructed and tested in the speaker's laboratory. Moreover, this talk describes a 750-V, 100-kW, 20-kHz bidirectional isolated dc-dc dual-active-bride (DAB) converter with focus on conversion efficiency and power-loss breakdown. The dc-dc converter consists of four 1.2-kV, 400-A SiC-MOSFET/SBD dual modules and magnetic devices including a 20-kHz transformer with a nano-crystalline soft-magnetic material. The SiC dual (two-in-one) module used in this experiment is the same in appearance, that is, size, shape, and terminal/pin arrangement as the latest 1.2-kV, 300-A Si-IGBT dual module.
Hirofumi Akagi Biography:
Hirofumi Akagi, professor and vice dean of the school of engineering at the Tokyo Institute of Technology, is a leading researcher in power conversion systems and their application to industry, utility and transportation. He has pioneered the theory of instantaneous reactive power in three-phase circuits, referred to as the “p-q theory,” which has been applied to power conversion systems and active filters for power conditioning. In addition, Dr. Akagi invented hybrid active-passive filters, the system concept and operating principle of which have been applied to the hybrid active-passive filter used in the Yamanashi test line for Japan's super high-speed, magnetically levitated train system. An IEEE Fellow, Dr. Akagi holds nine patents – with five more pending, and has authored or co-authored more than 70 IEEE Transactions/Journals. Dr. Akagi has received four IEEE Transactions Prize Paper Awards, the IEEE William E. Newell Power Electronics Award and the IEEE Industry Applications Society Outstanding Achievement Award.

HOTSIC - High temperature power electronic systems with SIC integrated circuits
Date and time: 24 April, 15:15, Teknikringen 33, lecture room H1
Venue: KTH Royal Institute of technology, Stockholm, Sweden
Speaker: Carl-Mikael Zetterling, KTH
SiC devices are already finding many application areas as more and more suppliers are bringing products on the market. Most of these products are aimed at high voltage applications, thanks to the high critical field for breakdown compared to silicon. This leads to much lower on-resistance for high voltage devices compared to silicon, but at a higher price that has to be offset by system gains. However, it is not straightforward to exploit this advantage, which is clear from the many different device types that are presently being commercialized. Lately several efforts have been started worldwide on high temperature SiC integrated circuits, exploiting the much higher intrinsic temperature of SiC compared to SOI. This could potentially lead to completely new applications in less cost-sensitive market areas. An overview and comparison will be made of SiC IC research technologies. Technological demands on material growth will also be included.

Lina Bertling - nominated as Treasurer of IEEE Power & Energy Society 2012/2013
The IEEE Power & Energy Society plays a leading role in global development of sustainable energy systems. Technological developments such as those conceptualized as the Smart Grid are crucial. The real difference, however, is made by the people. It is the energy in our network of people that creates miracles. I have found IEEE and PES to be a source of energy in my life. For the past thirteen years I have been actively involved in PES, serving on technical committees, editorial boards, leading the Swedish Chapter and organizing international conferences. As PES membership continues to grow at record paces, it becomes ever more crucial that we use our resources wisely. We must balance this growth with programs that are fiscally sustainable in the long run. As Treasurer of PES I would ensure that PES resources are used to maximize the benefit to our members. As a member of the Governing Board, I would work to strengthen PES outside of North America. I would serve PES with joy and pleasure, and I hope to have support from you! Thanks Lina.

On Concept of a Wide Area Defence System for the Power Grid
15-16: Guest lecturer Prof. Chen-Chin Liu University College Dublin. The purpose of a defence system is to help a power grid avoid a cascading sequence of events. Traditional N-1 security criterion does not assure that the system can withstand cascading outages. A wide area protection and control system with the capabilities to perform vulnerability assessment and determine the defence actions is needed. On line assessment should be based on vulnerable patterns of the power grid. Controlled islanding requires computational techniques to identify how the power grid will be partitioned. This seminar will provide simulation results with realistic test cases.
16-17: Discussion about IEEE and its benefits and features and specifically ideas for the the IEEE Sweden PE/PEL Chapter (moderator Prof. Lina Bertling).
Start: 2009-09-03 15:00
End 2009-09-03 17:00
Event location Department of Energy and Environment, Division of Electric Power Engineering, Hörsalsvägen 11, VD room
In view of revitalizing the Swedish PE/PES chapter, the Acting Chairman has scheduled a board meeting for early Septemeber. The intention is that a new chapter board will be elected in this meeting.
