In the inductive location method, high frequency magnetic fields generated by planar coils lead to induction in other coils, which is used for localization analysis. Magnetic fields are not affected by changes in the dielectric properties of the environment, which is an advantage over other localization methods. However, electrical material parameters can still affect the localization results by indirect effects. For this reason, in this publication the influence will be investigated using real material parameters and their effects on the localization will be considered, so that the robustness and the limits of the inductive localization can be evaluated.","lang":"eng"}],"status":"public","_id":"49890","user_id":"158","department":[{"_id":"59"},{"_id":"61"},{"_id":"485"}],"keyword":["Planar coils","inductive locating","magnetic fields","environmental influences","eddy currents","tet_topic_hf","tet_enas"],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"eisbn":["979-8-3503-2304-7"]},"place":"Genoa, Italy ","year":"2023","citation":{"ama":"Lange S, Hilleringmann U, Hedayat C, Kuhn H, Förstner J.

Als erste Stufe kommt ein PFC-Gleichrichter zum Einsatz, der die Anforderungen an den Netzstrom bezüglich Oberschwingungsgehalt und Leistungsfaktor sicherstellt. Für die zweite Wandler-Stufe hat sich in den vergangenen Jahren ein LLC-Resonanzwandler qualifiziert, der die Ladeleistung an die Traktionsbatterie galvanisch getrennt überträgt. Der Zwischenkreis besteht aus einer Bank von Elektrolytkondensatoren, in denen die pulsierende Eingangsleistung zwischengespeichert wird. Die Kondensatoren machen einen erheblichen Teil des Lader-Volumens aus und altern schnell, was insbesondere für Ladewandler an Bord von Elektrofahrzeugen unerwünscht ist. In der vorliegenden Arbeit wird untersucht, ob diese zweistufige Struktur verworfen werden kann, indem der LLC-Resonanzwandler direkt an die gleichgerichtete Netzspannung angeschlossen wird.Zum Einsatz des LLC-Resonanzwandlers als einstufiger Ladewandler ist die Schaltung für einen großen Strom- und Spannungsbereich auszulegen. Hierfür wird in der vorliegenden Arbeit eine erweiterte Zeitbereichsanalyse erarbeitet, deren hohe Modellierungsgenauigkeit im Anschluss experimentell nachgewiesen wird. Mit Hilfe dieser Zeitbereichsanalyse werden die Belastungsgrößen des Resonanzwandlers berechnet, um hiermit eine Vorauswahl der Schaltungsparameter treffen zu können. Darauf aufbauend erfolgt die Optimierung des integrierten Transformators als Schlüsselkomponente des Ladewandlers sowie dessen prototypische Realisierung. Abschließend wird mittels Prototypen die erzielbare Leistungsdichte ermittelt. Ergebnis: Verglichen mit etablierten Ladewandlern der heutigen Elektrofahrzeuge konnte durch den einstufigen Ansatz die Leistungsdichte um ca. 53% gesteigert werden."},{"text":"Today's on-board chargers of electric vehicles typically consist of two stages which are connected via a voltage DC link. A PFC rectifier is used as the first stage which ensures that the requirements for the mains current are met with respect to harmonic content and power factor. For the second converter stage, an LLC resonant converter has qualified in recent years which transmits the charging power to the traction battery in a galvanically isolated manner. The DC link consists of a bank of electrolytic capacitors in which the pulsating input power is buffered. The capacitors occupy a large portion of the charger volume and age rapidly, which is particularly undesirable for on-board chargers in electric vehicles. In the presented work, it is investigated whether this two-stage structure can be discarded by connecting the LLC resonant converter directly to the rectified line voltage.To use the LLC resonant converter as a single-stage charger, the circuit must be designed for a wide current and voltage range. For this purpose, an extended time-domain analysis is developed in this thesis, whose high modeling accuracy is subsequently demonstrated experimentally. With the help of this time domain analysis, the stress variables of the resonant converter are calculated in order to be able to make a preselection of the circuit parameters. Based on this, the optimization of the integrated transformer as a key component of the charger is carried out as well as its prototypical realization. Finally, the achievable power density is determined by means of prototypes. Result: Compared to established on-board chargers of today's electric vehicles, the single-stage approach increased the power density by about 53%.","lang":"eng"}],"status":"public","publisher":"LibreCat University","date_updated":"2025-02-18T09:06:48Z","date_created":"2025-02-18T09:05:22Z","author":[{"first_name":"Lukas","full_name":"Keuck, Lukas","id":"42519","last_name":"Keuck"}],"title":"Entwurf eines einstufigen Ladewandlers auf Basis eines LLC-Resonanzwandlers","doi":"10.17619/UNIPB/1-1727","year":"2023","citation":{"apa":"Keuck, L.

In this context, wide aperture automotive radars of 1m length or more and resolution close to 0.1° in azimuth and 0.5° in elevation could be beneficial. To enable coherent processing of arrays with such large aperture, prior (i.e offline) and online calibration are necessary: channel imbalances (gains and phases) and three dimensional coordinates of transmit and receive elements need to be determined. We propose a calibration strategy based on alternating steps between the two subtasks of i) channel imbalance estimation with ‘known’ array positions, by applying a singular value decomposition to the resulting tensor calculus problem; and ii) antenna position estimation with ’known’ channel imbalances, by numerically maximizing the Bayesian posterior probability; in both cases operating on range/Doppler snapshots of disjoint targets (with potentially unknown locations). Simulation studies based on the parameters of a MIMO 8x6 linear sparse array show promising results as long as the initial position errors do not exceed half a wavelength (2mm), beyond which we observe strong effects of ambiguity. Experimental results with real measurements show that after calibration in laboratory conditions, our MIMO 8x6 demonstrator with 50cm aperture is able to resolve two targets at the same range with angular separation at least as close as 0.4°.","lang":"eng"}],"status":"public","publication":"2023 24th International Radar Symposium (IRS)","type":"conference","language":[{"iso":"eng"}],"_id":"46426","department":[{"_id":"58"}],"user_id":"38254"},{"status":"public","abstract":[{"lang":"eng","text":"In this paper we present a new system architecture for software-defined radio / radar with optical signal distribution.

Furthermore, we can reuse parts, and under special conditions, also the complete optical output of the base station for the IQ return path from the wireless receiver frontends to the base station. Avoiding multiple lasers and fibers for the distribution of the carrier and arbitrary signal from the base station to the frontend, and avoiding the laser diode for the IQ return path from receiver frontends to the base station reduces the hardware effort significantly. Finally, the system architecture allows to integrate all components of the optoelectronic wireless frontend in a single chip using silicon photonics technology."}],"type":"conference","language":[{"iso":"eng"}],"user_id":"38254","department":[{"_id":"58"},{"_id":"230"}],"_id":"42800","citation":{"ama":"Kruse S, Kneuper P, Schwabe T, Meinecke M-M, Kurz HG, Scheytt JC.
