The lagging leg switches are subject to larger commutation currents compared to those of the leading leg as the transformer current reduces in the freewheeling interval. Furthermore, after this interval, the energy in the series inductance may not be large enough to achieve zero-voltage switching (ZVS) for the leading leg. Both effects result in thermal imbalances. This paper analyzes the alternating-asymmetrical phase-shift modulation to achieve balanced conduction and switching losses for all four switches while showing that this modulation is easily implemented on standard DSPs. The modulation has been implemented to LLC converters where experimental measurement results proved its effectiveness for LLC converters by reducing the temperature deviation from 6.3 K to only 0.2 K such that the peak temperature is reduced from 95 °C to 92 °C. The paper also proves that the modulation can be utilized to improve the efficiency of LLC converters operated at very low gains while simultaneously reducing the junction temperature of all four switches compared to the conventional complementary modulation. Finally, EMI implications are analyzed, which show that the modulation may be beneficial for reducing the common-mode emissions around the operating frequency.","lang":"eng"}],"status":"public","type":"conference","publication":"2021 IEEE Applied Power Electronics Conference and Exposition (APEC)","keyword":["Phase-Shifted Full Bridge","Full-Bridge Converter","Phase-Shift Control","Phase-Shift Modulation","LLC Converter","Thermal Balancing"],"language":[{"iso":"eng"}],"_id":"29893","user_id":"34289","department":[{"_id":"34"},{"_id":"52"}]},{"status":"public","abstract":[{"text":"LLC resonant converters are typically unsuitable to be applied for wide voltage-transfer ratio applications. With a full-bridge inverter, however, they can be operated in a variety of different modulations. Most notably, by permanently turning on one MOSFET and turning off the other MOSFET of the same bridge leg, the LLC can be operated in half-bridge configuration reducing the gain by a factor of two. The resonant capacitor is hereby charged to an average voltage of half the input voltage. In this modulation, however, the switch that is permanently turned on is stressed by the complete resonant current while exhibiting no switching losses. This paper proves that the frequency-doubler modulation can better balance the losses among all MOSFETs and should be the preferred mode of operation favored over the conventional half-bridge modulation. This paper analyzes the beneficial loss distribution, proposes an on-the-fly morphing modulation and discusses potential operating strategies to further reduce the junction temperature. Furthermore, it is shown that this modulation can also be altered to achieve the asymmetrical LLC operation. Experimental measurement results show that the modulation results in a substantial decrease of the maximum MOSFET temperature and shows that the converter can be smoothly transitioned during operation from full-bridge modulation to the frequency-doubler half-bridge operation and back.","lang":"eng"}],"type":"conference","publication":"23rd European Conference on Power Electronics and Applications (EPE'21 ECCE Europe)","language":[{"iso":"eng"}],"keyword":["Resonant converter","High frequency power converter","Switched-mode power supply","Converter control","Control methods for electrical systems"],"user_id":"34289","department":[{"_id":"34"},{"_id":"52"}],"_id":"29899","citation":{"ieee":"P.

To achieve this, it is necessary to employ an appropriate process or tool design. While this will generally prove successful, it cannot, however, offset stochastic defects with local variations in material properties. Closed-loop process control represents a promising approach for a solution in this context. The state of the art involves using this approach to control geometric parameters such as a length. So far, no research or applications have been conducted with closed-loop control for microstructure and product properties. In the project on which this paper is based, the local martensite content of parts is to be adjusted in a highly precise and reproducible manner. The forming process employed is a special, property-controlled flow-forming process. A model-based controller is thus to generate corresponding correction values for the tool-path geometry and tool-path velocity on the basis of online martensite content measurements. For the controller model, it is planned to use a special process or microstructure (correlation) model. The planned paper not only describes the experimental setup but also presents results of initial experimental investigations for subsequent use in the closed-loop control of α’-martensite content during flow-forming.","lang":"eng"}],"publisher":"ULiège Library","date_created":"2021-08-23T13:00:35Z","title":"Forming of metastable austenitic stainless steel tubes with axially graded martensite content by flow-forming","quality_controlled":"1","year":"2021"},{"doi":"10.36001/phme.2021.v6i1.3042","conference":{"name":"PHM Society European Conference"},"main_file_link":[{"open_access":"1","url":"http://papers.phmsociety.org/index.php/phme/article/download/3042/1812"}],"volume":6,"author":[{"last_name":"Aimiyekagbon","full_name":"Aimiyekagbon, Osarenren Kennedy","id":"9557","first_name":"Osarenren Kennedy"},{"first_name":"Lars","last_name":"Muth","orcid":"0000-0002-2938-5616","full_name":"Muth, Lars","id":"77313"},{"first_name":"Meike Claudia","id":"43991","full_name":"Wohlleben, Meike Claudia","orcid":"0009-0009-9767-7168","last_name":"Wohlleben"},{"first_name":"Amelie","last_name":"Bender","full_name":"Bender, Amelie","id":"54290"},{"first_name":"Walter","last_name":"Sextro","id":"21220","full_name":"Sextro, Walter"}],"date_updated":"2023-09-22T09:13:01Z","oa":"1","intvolume":"         6","page":"527-536","citation":{"apa":"Aimiyekagbon, O.

However, an increase in model accuracy with state-of-the-art methods, such as deep convolutional neural networks, results in less interpretability and transparency. Due to the ease of implementation, interpretation and transparency to both domain experts and non-experts, a rule-based method is proposed in this paper, for prognostics and health management (PHM) and specifically for diagnostics. The proposed method utilizes the most relevant sensor signals acquired via feature extraction and selection techniques and expert knowledge. As a case study, the presented method is evaluated on data from a real-world quality control set-up provided by the European prognostics and health management society (PHME) at the conference’s 2021 data challenge. With the proposed method, our team took the third place, capable of successfully diagnosing different fault modes, irrespective of varying conditions.","lang":"eng"}],"publication":"Proceedings of the European Conference of the PHM Society 2021"},{"doi":"10.1109/tie.2020.3018060","title":"Comparison of Gray-Box and Black-Box Two-Level Three-Phase Inverter Models for Electrical Drives","volume":68,"author":[{"last_name":"Stender","id":"41240","full_name":"Stender, Marius","first_name":"Marius"},{"full_name":"Wallscheid, Oliver","id":"11291","last_name":"Wallscheid","orcid":"https://orcid.org/0000-0001-9362-8777","first_name":"Oliver"},{"full_name":"Böcker, Joachim","id":"66","orcid":"0000-0002-8480-7295","last_name":"Böcker","first_name":"Joachim"}],"date_created":"2022-02-24T09:26:06Z","date_updated":"2022-02-24T09:26:45Z","publisher":"Institute of Electrical and Electronics Engineers (IEEE)","intvolume":"        68","page":"8646-8656","citation":{"chicago":"Stender, Marius, Oliver Wallscheid, and Joachim Böcker. “Comparison of Gray-Box and Black-Box Two-Level Three-Phase Inverter Models for Electrical Drives.” <i>IEEE Transactions on Industrial Electronics</i> 68, no. 9 (2020): 8646–56. <a href=\"https://doi.org/10.1109/tie.2020.3018060\">https://doi.org/10.1109/tie.2020.3018060</a>.","ieee":"M.

Considering one vortex, we define a time minimization problem which can be analyzed with the technics of geometric optimal control combined with numerical simulations, the geometric frame being the extension of Randers metrics in the punctured plane, with rotational symmetry. Candidates as minimizers are parameterized thanks to the Pontryagin Maximum Principle as extremal solutions of a Hamiltonian vector field. We analyze the time minimal solution to transfer the ship between two points where during the transfer the ship can be either in a strong current region in the vicinity of the vortex or in a weak current region. The analysis is based on a micro-local classification of the extremals using mainly the integrability properties of the dynamics due to the rotational symmetry. The discussion is complex and related to the existence of an isolated extremal (Reeb) circle due to the vortex singularity. The explicit computation of cut points where the extremal curves cease to be optimal is given and the spheres are described in the case where at the initial point the current is weak.</jats:p>","lang":"eng"}],"status":"public","type":"journal_article","publication":"ESAIM: Control, Optimisation and Calculus of Variations","article_number":"S10","keyword":["Computational Mathematics","Control and Optimization","Control and Systems Engineering"],"language":[{"iso":"eng"}],"_id":"33866","user_id":"95394","year":"2020","citation":{"short":"B.

They can extend their lifetime at the cost of lowered performance or vice versa. This can be used to adapt failure behavior according to a maintenance plan, thus increasing availability while using up system capability fully. To facilitate setup, a control algorithm independent of a degradation model is desired. A closed loop control technique for reliability based on a health index, a measure for system degradation, is introduced. It uses self-optimization as means to implement behavior adaptation. This is based on selecting the priorities of objectives that the system pursues. Possible working points are computed beforehand using model-based multiobjective optimization techniques. The controller selects the priorities of objectives and this way balances reliability and performance. As exemplary application, an automatically actuated single plate dry clutch is introduced. The entire reliability control is setup and lifetime experiments are conducted. Results show that the variance of time to failure is reduced greatly, making the failure behavior more predictable. At the same time, the desired usable lifetime can be extended at the cost of system performance to allow for changed maintenance intervals. Together, these possibilities allow for greater system usage and better planning of maintenance.","lang":"eng"}],"status":"public"},{"keyword":["Beliefs","Competency Based Teacher Education","Control Groups","Early Childhood Education","Faculty Development","Foreign Countries","Inservice Teacher Education","Intervention","Mathematical Aptitude","Mathematics Skills","Pedagogical Content Knowledge","Preschool Teachers","Pretests Posttests","Professional Continuing Education","Statistical Analysis","Teacher Competency Testing"],"extern":"1","language":[{"iso":"eng"}],"_id":"36481","user_id":"49063","department":[{"_id":"611"},{"_id":"97"}],"abstract":[{"text":"Recent studies highlight early childhood teachers’ mathematics-related competence.

To answer these questions, we conducted a pre-test/post-test study including a control group with 99 in-service early childhood teachers. Results show that the course affected teachers’ mathematical pedagogical content knowledge and static orientation towards mathematics positively.

The concept is\r\nseamlessly integrated into Mercurial---respecting its distributed storage\r\nconcept---to ensure practical usability and compatibility to existing\r\ndeployments."}],"status":"public","_id":"19","department":[{"_id":"27"},{"_id":"518"}],"user_id":"24135","keyword":["access control","distributed version control systems","mercurial","peer-to-peer","convergent encryption","confidentiality","authenticity"],"language":[{"iso":"eng"}],"publication_identifier":{"isbn":["978-1-5090-2054-6"]},"publication_status":"published","year":"2016","citation":{"apa":"Lass, M., Leibenger, D., &#38; Sorge, C.
