Zero‐Current Switching Based Model Predictive Control of a Double‐Extended Overlapped Alternate Arm Converter Used in the VSC–HVDC System

open access: yesHigh Voltage, EarlyView.
ABSTRACT The alternate arm converter (AAC) is one of the most efficient multilevel topologies based on voltage source converters (VSCs), which has recently gained attention in various applications, particularly in high voltage direct current (HVDC) systems.

RH -ZCs

open access: yes
This work presents ZCS–RH, a Zero-Centric System framework offering a structural and conceptual perspective related to the Riemann Hypothesis. The approach treats zero as an organizing element in numerical and positional systems, exploring digit-space behavior, numerical transitions, and structural patterns relevant to prime distribution.

Resonante ZCS-Konverter mit beschränktem Arbeitsbereich

open access: yese & i Elektrotechnik und Informationstechnik, 2023
ZusammenfassungDC/DC-Konverter wandeln eine Eingangsspannung in eine Ausgangsspannung. In diesem Beitrag werden drei solche Konverter behandelt, die aus den drei Grundschaltungen hergeleitet sind. Im Gegensatz zu den Originalstrukturen sind diese nur für einen geringeren Spannungsübersetzungsbereich geeignet, haben aber den Vorteil, dass die ...

Can LLMs Simulate Target Users in Visualization Case Studies?

open access: yesComputer Graphics Forum, EarlyView.
Abstract Case studies are central to evaluating visualization research as they provide evidence for how the developed approaches support real users, real analytical work, and real data. Conducting such studies can be challenging, since target users with relevant domain expertise are often scarce or even entirely unavailable, while the visualization ...

Photostability and visible-light-driven photoactivity enhancement of hierarchical C@ZnCdS/ZnS/MoS2

open access: yesNano Express
Zinc cadmium sulfide solid (Zn _x Cd _1− _x S) related composites received great attention in photocatalytic hydrogen production because of their tunable bandgap and strong visible light absorption range. But sulfide-based metal materials commonly suffer
