In these systems operating at high frequencies, the ratio of dead-time versus the operating period becomes critical, and the dead-time issue can cause certain problems regarding power quality, efficiency, and output voltage ripple. The impact of input quantities such as voltage and switching frequency on the efficiency and output power of the LCC-S-tuned WPT system was also investigated. The optimal combination of these parameters used to achieve the maximum efficiency for a target output power and to set the appropriate value of the dead time were determined by running multiple simulations using the MATLAB R2023b software platform. It was also shown that the output voltage remained unchanged with and without a load and up to 1200 ns of dead-time, which provides a simple implementation of the corresponding mathematical model. In the recommended interval of 600–1500 ns, the influence of the dead-time on the value of the output voltage amplitude is less than 10%. The validity of the proposed method was confirmed through the implementation of the experimental prototype, a 5 kW wireless power transmission system, and the obtained results were in accordance with the simulation results.}, year = {2024}, eissn = {2079-9292}, orcid-numbers = {Rajs, Vladimir/0000-0003-4357-770X; Despotović, Živadin/0000-0001-7277-9453; Kiraly, Zoltan/0000-0002-6808-3856} } @article{MTMT:34448557, title = {Continuous Electrode Models and Application of Exact Schemes in Modeling of Electrical Impedance Measurements}, url = {https://m2.mtmt.hu/api/publication/34448557}, author = {Vizvári, Zoltán Ákos and Klincsik, Mihály and Odry, Péter and Tadity, Vladimir and Győrfi, Nina Rubina and Tóth, Attila and Sári, Zoltán}, doi = {10.3390/electronics13010066}, journal = {ELECTRONICS (SWITZ)}, volume = {13}, unique-id = {34448557}, abstract = {The crucial issue in electrical impedance (EI) measurements lies in the galvanic interaction between the electrodes and the investigated material. This paper brings together the basic and applied research experience and combines their results with excellent properties. Consequently, innovative precise methodologies have emerged, enabling the direct modeling of EI measurements, free from the inaccuracies often associated with numerical approaches. As an outcome of the efficiency and robustness of the applied method, the conductivity of the material and the electrodes are represented by a common piecewise function, which is used to solve the differential equation modeling of the EI measurement. Moreover, this allows the possibility for modeling the conductivity of electrodes with continuous functions, providing an important generalization of the Complete Electrode Model (CEM), which has been widely used so far. The effectiveness of the novel approach was showcased through two distinct case studies. In the first case study, potential functions within both the material and the electrodes were computed using the CEM. In the second case study, calculations were performed utilizing the newly introduced continuous electrode model. The simulation results suggest that the new method is a powerful tool for biological research, from in vitro experiments to animal studies and human applications.}, year = {2024}, eissn = {2079-9292} } @techreport{MTMT:34549759, title = {Szimulációs mérések szerepe a térérzékelésben}, url = {https://m2.mtmt.hu/api/publication/34549759}, author = {Sebők-Tornai, Bence and Várady, Géza}, unique-id = {34549759}, abstract = {A Magyar Tudományos Akadémia Pécsi Területi Bizottsága VI. sz.

This paper focuses on replacing the complex energy and comfort simulation procedure with fast regression model-based processes that encounter the building shape as input. Numerous building shape descriptors were applied as inputs to several regression models. After evaluating the results, it can be stated that, with careful selection of building geometry describing design input variables, complex energy and comfort simulations can be approximated. Six different models with five different building shape descriptors were tested. The worst results were around R2 = 0.75, and the generic results were around R2 = 0.92. The most accurate prediction models, with the highest level of accuracy (R2 > 0.97), were linear regressions using 3rd power and dense neural networks using 1st power of inputs; furthermore, averages of mean absolute percentage errors are 1% in the case of dense neural networks. For the best performance, the building configuration was described by a discrete functional point cloud. The proposed method can effectively aid future building energy and comfort optimization processes.}, year = {2023}, eissn = {1996-1073}, orcid-numbers = {Storcz, Tamás/0000-0003-1656-5463; Várady, Géza/0000-0001-5427-913X; Ercsey, Zsolt/0000-0002-7536-3688} }
