In this context, immune-inspired concepts offer suitable characteristics for developing lightweight fault detection systems, and previous works have shown promising results. In this article, we provide a literature review of immune-inspired fault detection approaches in sensor networks proposed in the last two decades. We discuss the unique properties of the human immune system and how the found approaches exploit them. With the information from the literature review extended with the findings of our previous works, we discuss the limitations of current approaches and consequent future research directions. We have found that immune-inspired techniques are well suited for lightweight fault detection, but there are still open questions concerning the effective and efficient use of those in sensor networks.}, subject = {fault detection}, language = {en} } @article{HimmelstossJungmayer, author = {Himmelstoß, Felix and Jungmayer, Michael}, title = {Resonante ZCS Konverter mit beschr{\"a}nktem Arbeitsbereich}, series = {e \& i Elektrotechnik und Informationstechnik}, journal = {e \& i Elektrotechnik und Informationstechnik}, number = {140}, doi = {10.1007/s00502-022-01113-1}, pages = {123 -- 131}, abstract = {DC/DC-Konverter wandeln eine Eingangsspannung in eine Ausgangsspannung.

disadvantage of pronounced aging. Non-electrolytic capacitors are therefore used in applications where long-life is important. In this paper we present a driving stage for LEDs without any capacitive elements. The basic topology is a Buck converter with one coil, one active, and one passive switch. Instead of the output capacitor, series connections of one or more LEDs and an active switch are connected. An additional diode is connected between the output and the input to achieve a current path, when all LED- paths are off. A nonlinear hysteresis controller is used to achieve a robust control. A system with three switchable LED-strings is analyzed. Design hints are given and the function is proved with the help of LTSpice simulations. The system can be used for lighting purposes with the possibility to change the chrominance. The potentiality to transmit data is also treated.}, subject = {DC-to-DC converter}, language = {en} } @inproceedings{HimmelstossWindisch, author = {Himmelstoss, Felix and Windisch, Michael}, title = {Tapped inductor Boost with exploitation of the stray energy}, series = {Proceedings of 2022 IEEE 20th International Power Electronics and Motion Control Conference (PEMC 2022), Brasov, Rumania, Sep. 25-29}, booktitle = {Proceedings of 2022 IEEE 20th International Power Electronics and Motion Control Conference (PEMC 2022), Brasov, Rumania, Sep. 25-29}, doi = {10.1109/PEMC51159.2022.9962849}, pages = {75 -- 80}, abstract = {Tapped inductor DC-to-DC converters are interesting circuits, the winding ratio of the two windings mounted on the same core change the voltage transformation ratio compared to the untapped inductor. The tapped inductor converters are especially useful, when high or low voltage transformation ratios have to be realized. The disadvantage of this concept is that the coupling between the two windings is not total and can be described by the stray or leakage inductance. This stray inductance leads to a high overvoltage at the active switch, and therefore also across other elements of the converter. After a short summery of the ideal tapped Boost converter, the design of an RCD snubber which limits the overvoltage is explained. To improve the efficiency of the converter two active snubber networks are treated, which feed the energy stored in the snubber capacitor into the input source or into the output circuit.
