The concept is based on integration of the power switches with both the cooling system and the DC link capacitor, which optimizes the thermal management and minimizes inductive and conductive losses. The materials and joining technologies are selected in such a way that the converter can be operated up to 125 C ambient temperature. Therefore, the water cooling system of the combustion engine can directly be used. The paper further reports on circuit simulation results verifying the converter design and on first electrical measurements obtained on a functional prototype operating under normal load conditions (6kW rated power).}, language = {de} } @inproceedings{GerberFerreiraHofsajeretal.2003, author = {Gerber, M. and Ferreira, J.A. and Hofsajer, I.W. and Seliger, Norbert}, title = {High temperature, high power density packaging for automotive applications}, series = {IEEE 34th Annual Conference on Power Electronics Specialist, 2003.

Currently, the power electronics that is implemented within the engine compartment of the vehicle must operate with heatsink temperatures of approximately 85/spl deg/C and this temperature can be expected to increase to 125/spl deg/C in the near future. The high temperature operation of the power electronic structure is fundamentally limited by the employed materials maximum temperatures. A packaging concept is introduced that describes a structure realisation that enables the materials to operate at high ambient temperatures without exceeding their individual maximum temperatures. This in turn allows the complete power electronic structure to operate at a higher system temperature. In this paper, the packaging concept that can be used to meet these difficult requirements of high temperature and high power-density is introduced, discussed and implemented. Two case studies are considered and implemented to illustrate the packaging concept.}, language = {en} } @inproceedings{SeligerRacklesSchwarzbaueretal.2002, author = {Seliger, Norbert and Rackles, J. and Schwarzbauer, H. and Kiffe, W. and Bolz, S.}, title = {Compact and robust power electronics packaging and interconnection technology for an Integrated Starter Generator}, series = {Optimization of the Power Train in Vehicles by Using the Integrated Starter Generator (ISG)}, booktitle = {Optimization of the Power Train in Vehicles by Using the Integrated Starter Generator (ISG)}, publisher = {expert verlag GmbH}, isbn = {9783816920779}, pages = {248 -- 255}, year = {2002}, language = {en} } @inproceedings{RacklesSeliger2003, author = {Rackles, J. and Seliger, Norbert}, title = {Optimization of DC-Link Capacitors in an Integrated Starter Generator Unit}, series = {The New Automotive 42V Power Net}, booktitle = {The New Automotive 42V Power Net}, editor = {Graf, A.}, publisher = {expert verlag}, isbn = {978-3-8169-1992-6}, year = {2003}, language = {en} } @inproceedings{FuerboeckThalhammerLitzenbergeretal.1999, author = {F{\"u}rb{\"o}ck, C. and Thalhammer, R. and Litzenberger, M. and Seliger, Norbert and Pogany, D. and Gornik, E. and Wachutka, G.}, title = {Internal Characterisation of IGBTs Using the Backside Laserprober Technique}, series = {Jahrestagung der GMe, Bad Hofgastein Tagungsband 1999}, booktitle = {Jahrestagung der GMe, Bad Hofgastein Tagungsband 1999}, publisher = {Gesellschaft f{\"u}r Mikroelektronik (GMe)}, isbn = {3-901678-04-8}, year = {1999}, language = {en} } @inproceedings{SeligerFaltlhauser2023, author = {Seliger, Norbert and Faltlhauser, Georg}, title = {Progressive Expansion Sampling of Quasi-Static Magnetic Fields for EMI Noise Detection and Equivalent Source Modeling}, series = {Proceedings EMC Europe 2023}, booktitle = {Proceedings EMC Europe 2023}, publisher = {IEEE}, address = {Krakov}, pages = {6}, year = {2023}, abstract = {We introduce a quick and accurate quasi-static magnetic field scanning technique by employing a progressive sampling method in an unconfined input space.
