One use case for Virtual Commission- ing (VC) is the early software test without an existing plant. The primary effort of VC lies in the manual creation of the plant model. There are various simulation tools with different advantages available. Selecting one tool has consequences for the whole engineering process. The exchange of models across different tools is not possible or discouraged by the respective vendors due to various reasons. This paper describes a concept to exchange behavior models via the table-based import interfaces for an automated model generation within common simulation tools. The concept utilizes an approach to exchange the behavior of components using the vendor-neutral and standardized pro- gramming language PLCopenXML containing all IEC 61131-3 programming languages. This removes the main obstacle for a broader industrial application of VC, as it minimizes the manual effort for creating and exchanging behavior models through the use of standardized library elements and existing interfaces.}, language = {en} } @inproceedings{GerstnerMaerzDietz2020, author = {Gerstner, Michael and Maerz, Martin and Dietz, Armin}, title = {Design of a Wide Input Voltage Range Current-Fed DC/DC Converter Within a Reduced Duty-Cycle Range}, series = {2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe)}, booktitle = {2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe)}, publisher = {IEEE}, doi = {https://doi.org/10.23919/epe20ecceeurope43536.2020.9215825}, pages = {10}, year = {2020}, abstract = {A design of a current-fed push-pull converter for wide input voltage ranges within a reduced duty-cycle range is presented. Based on the converter conversion ratios of three different clamping configurations, the potential of the input clamping is shown analytical, simulative and by measurements. A differentiation is made between the four possible operating modes, which can be distinguished in the control of the semiconductors and the magnetomotive force in the reactor. By optimizing the turn ratios of both transformers, the wide input voltage range capability of the input clamped current-fed push-pull converter was improved, which has been proved by measurements on a real prototype.}, language = {en} } @inproceedings{GerstnerMaerzDietz2020, author = {Gerstner, Michael and Maerz, Martin and Dietz, Armin}, title = {Reconfigurable Transformer for Wide Input Voltage Range DC/DC Converters}, series = {2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia)}, booktitle = {2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia)}, publisher = {IEEE}, doi = {https://doi.org/10.1109/ipemc-ecceasia48364.2020.9367869}, year = {2020}, abstract = {A transformer with variable primary windings for wide input voltage range DC/DC converters is presented. This transformer structure allows three states of the primary winding to be converted by only two individual windings. Based on the evaluations of a two-switch flyback converter, the potential of DC/DC converters with variable structures, the implementation of such a transformer and the advantages and disadvantages are shown and discussed. Real measurement results demonstrate the noticeable increase in efficiency and the reduction in component stress, having a positive influence on the operation of the converter and the component selection during the design process.}, language = {en} }
