EPE'97 : DISCUSSION SESSIONS ------------------------------------------------------------------------ Some workshops will issue a written report of the discussions. The final programme will be available on site Application specific power modules Animators: Denis R. Grafham, European Applications, Advanced Power Technology Inc., Rixensart, Belgium and Serge Bontemps, Manager Engineering, Advanced Power Technology Europe, Mérignac, France Topic: The fastest route to highly-integrated power management solutions. Marries high performance to cost effectiveness, state-of-the-art packaging with insurance against reverse engineering. Issues for discussions: - Where are ASPMs relevant? - Are custom power modules really cost effectives? - How do ASPMs relate to modern silicon technology? - What are the most approrpiate substrate materials? - Air or water cooling? - How to optimize electronic circuit design. - Driver, protection and supervisory accessories. - Packaging flexibility. - Input and out[ut bussing, power and signal. - Noise immunity. - Power circuit layout for minimum strays. - Environmental considerations. - Use of Surface Mount Components. - Reliability. The relationship between users and manufacturers in power electronics Animator: Enrique J. Dede, Professor of Power Electronics at the University of Valencia and R&D Director of GH-ELIN, Secretary: José A. Carrasco, Assistant Professor of Power Electronics at the University of Valencia Topic: The aim of the discussion will be to explore the needs of the users of power electronics related to active components, passive components as well as the specification of the components and other requirements as standardisation, regulations etc... in order to make a list of "wishes" and to find out what manufacturers can provide from this list of wishes. High power integration, Animator: Prof. André A. Jaecklin, ABB Corporate Research, Secretary: Dr. Stefan Linder, ABB Semiconductors Topics: a. IGBT: - module construction (e.g. high frequency design) - high voltage devices - high current devices (large scale parallel connection) - reliability problems (partial discharge; testing methods) b. IGCT - basic concept - drive circuits - optimum snubber - applications. Smart power in the automotive industry Animator: K. Rischmuller, SGS Thomson Topic description not available at time of printing Smart power in dc-dc converters below 100 W P. Lindman, Ericsson Components - integration of passive components - cost vs. integration level - flexibility vs. integration level - performance: integration vs. discrete - encapsulation Impact of integration on power electronic design Animators: Jean Marie Peter, SEE and Consulting; Prof. Philippe Lataire, Vrije Universiteit Brussel The data processing job was completely transformed by the signal integration. The power integration is coming slowly, because there are a lot of specific problems in power (Thermal, current density, mutual component interaction, cost, etc..), but will arrive in the market. What could be the consequences in power electronics. GTO or IGBT Animators: Jean Marie Peter, SEE and Consulting; Prof. Philippe Lataire, Vrije Universiteit Brussel A lot of progresses have been done in the field of high power IGBT. This component is now from 200 kW to several Megawatts a useful device. A big progress has already been done with the hard driven GTO called GCT. What are the main advantages and disadvantages of each components, what could be the optimal application field? Teaching Animator: Dr. Richard Duke, University of Canterbury, New Zealand The occasion of EPE brings the rare opportunity for international comparisons of power electronics educational systems. Each country of group of closely associated countries has developped its own unique educational system and power electronics education has developed and flourished in different ways to meet varying needs. What position does (should) power electronics hold in the undergraduate (graduate) programme? Should power electronics be a required course for all EE's, for all EE's specialising in power or is an elective arrangement more appropriate? There is a commonly held perception that power electronics education is often inadequate, especially with respect to practical experience in instructional laboratories. Should lectures and laboratories be an integrated package or are separate laboratory courses more appropriate? Are the traditional electrical machnies courses still appropriate or should there be more effort to integrate power electronics into such courses? To initiate discussion of these question, and others, some brief results from international survey of power electronics education in Australasian and North American Universities will be presented. Software Packages and Experiences in Simulating Power Electronics and Motor Drives Animators: Prof. Ned Mohan, Dept. of Electrical Engineering, Univ. of Minnesota, Minneapolis, USA; Prof. Eisuke Masada, Tokyo University In this discussion group, capabilities of various simulation packages will be presented for modeling of power electronics and motor drives. Users of these packages will describe their experiences. FACTS Animators: Prof. Hirofumi Akagi, Okayama University and Prof. Tore Undeland, NTNU, Norway This discussion session provides an informal discussion about the state of the art of FACTS devices, and about future prospects and directions, including the personal views and expectations of participants. EMC Animator: Prof. Paolo Tenti, University of Padova - CISPR and IEC standards regarding conducted and radiated noise emission and immunity - typical problems arising from their application - mitigation guidelines Sensorless ac drives moderator to be chosen Topic description not available at time of printing Large industrial drives Animators: Jacques Coureault, Directeur Technique and Henri Godfroid, Chef de Service, Division Ensembles Industriels, CEGELEC Machine/Converters arrangements commonly used and new trends.
