Drofenik, Uwe,Kolar, Johann W. The Korean Institute of Power Electronics 2002 JOURNAL OF POWER ELECTRONICS Vol.2 No.4
This paper introduces the Interactive Power Electronics Seminar - iPES - a new software package for teaching of fundamentals of power electronic circuits and systems. iPES is constituted by HTML text with Java applets for interactive animation, circuit design and simulation and visualization of electromagnetic fields and thermal issues in power electronics. It does comprise an easy-to-use self-explaining graphical user interface. The software does need just a standard web-browser, i.e. no installations are required. iPES can be accessed via the World Wide Web or from a CD-ROM in a stand-alone PC by students and professionals. Due to the underlying software technology iPES is very flexible and could be used for on-line learning and could easily be integrated into an e-learning platform. The aim of this paper Is to give an introduction to the iPES-project and to show the different areas covered. The e- learning software is available at no costs at $\underline{www.ipes.ethz.ch}$ in English, German, Japanese, Korean, Chinese and Spanish. The project is still under development and the web page is updated in about 4 weeks intervals.

The effect of B2O3-Bi2O3 glass additions on exaggerated grain growth in donordoped barium titanate
M. Drofenik,I. Zajc,D. Makovec 한양대학교 세라믹연구소 2004 Journal of Ceramic Processing Research Vol.5 No.2
Interactions between BaTiO3 and the B2O3-Bi2O3 system were studied by sintering BaTiO3 with B2O3/Bi2O3 glass powder. In general, the microstructural development of BaTiO3 depends very much on the amount and composition of glassy phase present in the samples during sintering. With large amounts of B2O3-Bi2O3 glassy phase and, as a consequence, a high Bi3+ donor-dopant concentration, the grain growth is suppressed. On the other hand, when the amount of donor-dopant supplied by the glassy phase decreases, the grain growth occurs, leading to the formation of semiconducting ceramics. All prepared samples exhibited the Positive Temperature Coefficient Resistivity (PTCR) effect.

Weight Minimization of LCL Filters for High Power Converters
Ki-Bum Park,Frederick Kieferndorf,Uwe Drofenik,Sami Pettersson,Francisco Canales 전력전자학회 2015 ICPE(ISPE)논문집 Vol.2015 No.6
Weight reduction of the LCL filter is one of the main concerns for high power, grid connected, voltage source converters (VSC) where an LCL filter can weigh hundreds of kilograms. It is a multi-domain optimization issue to find the minimum weight of an LCL filter considering PWM, control, filter design, and magnetic components with given constraints such as harmonic standards, semiconductor power loss, and cooling condition. The comprehensive design procedure and limits of an LCL filter for a 1.2-MVA VSC is provided in this paper.
