Improved predictive current control technique for a zero current switched buck-boost series resonant inverter

open access: yes, 1993
An improved predictive current control technique for a zero current switched (ZCS) buck-boost series resonant inverter (SRI) is proposed to overcome the inherent disadvantages such as the uncontrollable large overshoot and the large current ripple. Using

System‐Level Performance and Techno‐Economic Assessment of Rooftop Four‐Terminal Tandem Photovoltaic Systems With Module‐Level Power Electronics Under Partial Shading

open access: yesSolar RRL, Volume 10, Issue 20, 28 October 2026.
Module‐level power electronics enable independent operation of top and bottom submodules in four‐terminal tandem photovoltaic systems while reducing shading‐induced mismatch losses. A comprehensive system‐level and techno‐economic assessment identifies submodule‐level architectures as the most effective solution under moderate and high shading, with ...

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

open access: yesAdvanced Engineering Materials, Volume 28, Issue 20, 21 October 2026.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.
