In many publications, the common mode (CM) noise is not taken into account. However, this must not be neglected considering the large effective capacitance, of up to 3 muF, as allowed by new standards. In this paper, different modulation techniques are investigated, related to their CM-noise. Based on electric circuit simulations, CM-filters are estimated, and the CM-currents are investigated. Accordingly, the conventional six-switch full-bridge is practically difficult to use in non-isolated chargers, because the resulting CM-currents and/or the required EMI-filter become too large, even if CM-Voltage optimized modulation techniques are used.}}, author = {{Strothmann, Benjamin and Schafmeister, Frank and Böcker, Joachim}}, booktitle = {{PCIM Europe 2019; International Exhibition and Conference for Power Electronics, Intelligent Motion, Renewable Energy and Energy Management}}, pages = {{1--7}}, title = {{{Common Mode Analysis of Non-Isolated Three-Phase EV-Charger for Bi-Directional Vehicle-to-Grid Operation}}}, year = {{2019}}, } @inproceedings{30002, abstract = {{Utilisation of SiC semiconductors' fast switching speeds and high switching frequencies as a consequent are often in discussion. But which switching frequency is really optimal in terms of converter volume, losses and costs? Based on the example of a buck converter, this question is investigated, and a tool for loss calculation and design is described in this paper. A Pareto optimization of the converter is performed where the switching frequency is one of several design parameters. The buck converter can be realized by multiple rails interleaved, and several switches can be placed in parallel. Considered converter modes are continuous conduction mode, that allows hard-switching, ZVS, and incomplete ZVS depending on the switching frequency. Based on Pareto optimizations, a design is selected, and a laboratory sample of 5.5 kW for application in an EV battery charger is built up. Efficiencies of 99.5 % are achieved with switching frequencies of around 100 kHz.}}, author = {{Strothmann, Benjamin and Schafmeister, Frank and Böcker, Joachim}}, booktitle = {{2019 IEEE Applied Power Electronics Conference and Exposition (APEC)}}, publisher = {{IEEE}}, title = {{{Pareto Design and Switching Frequencies for SiC MOSFETs Applied in an 11 kW Buck Converter for EV-Charging}}}, doi = {{10.1109/apec.2019.8721850}}, year = {{2019}}, } @inproceedings{16442, author = {{Rehlaender, Philipp and Grote, Tobias and Schafmeister, Frank and Böcker, Joachim}}, booktitle = {{PCIM Europe 2019}}, location = {{Nürnberg}}, title = {{{Analytical Modeling and Design of an Active Clamp Forward Converter Applied as a Single-Stage On-Board DC-DC Converter for EVs}}}, year = {{2019}}, } @inproceedings{29942, abstract = {{Due to recent developments in MMCs, they are used in many medium-voltage and high-power applications today, but efficient and modular solutions for high-power at low-voltage such as for electrolysis are still required.

The issues are the rapid digitalization and development of health and welfare technology, which presently is mainly technology driven (not need or user driven), and the demographic challenge. The aim of the study was to explore older adults’ perception of the future use of welfare technology or care robots. A qualitative approach with focus group discussions was employed, followed by thematic analysis. The results are presented in four overall themes: the impact on daily life for older adults and professional caregivers, codes of practice and terms of use, dissemination of information and knowledge, and conditions for successful implementation. There were significant differences in the informants’ attitudes toward and knowledge about care robots. However, the informants’ attitudes appeared to change during the focus groups and in general, became more positive. Authentic needs, which care robots could support, refer to independence, safety and security, and the ability to manage or ease daily life or working life. The results suggest that older adults, after receiving relevant information, were open to the idea of being supported by care robots in their daily lives.}}, author = {{Johansson-Pajala, Rose-Marie and Thommes, Kirsten and Hoppe, Julia Amelie and Tuisku, Outi and Hennala, Lea and Pekkarinen, Satu and Melkas, Helinä and Gustafsson, Christine }}, booktitle = {{HCII 2019}}, editor = {{Zhou, Jia and Salvendy, Gavriel}}, isbn = {{978-3-030-22011-2}}, keywords = {{Care robots, Older adults, Implementation, Information, Perceptions, Welfare technology}}, location = {{Orlando}}, pages = {{212--227}}, publisher = {{Springer}}, title = {{{Improved Knowledge Changes the Mindset: Older Adults’ Perceptions of Care Robots}}}, doi = {{10.1007/978-3-030-22012-9_16}}, volume = {{11592}}, year = {{2019}}, } @inproceedings{30334, author = {{Keuck, Lukas and Schafmeister, Frank and Böcker, Joachim}}, booktitle = {{Proc. 34th IEEE Applied Power Electronics Conference (APEC)}}, location = {{Anaheim, CA, USA}}, pages = {{1415 -- 1422}}, publisher = {{IEEE}}, title = {{{Computer-Aided Design and Optimization of an Integrated Transformer with Distributed Air Gap and Leakage Path for an LLC Resonant Converter}}}, year = {{2019}}, }
